Preface

The first International Mathematical Olympiad (IMO) was held in 1959, i.e. 50 years ago,

in Romania. This IMO was initiated by the Romanian Society for Mathematics and

Physics, which had a long tradition in competitions for students in these fields. The

invitations were given – in the first years to European socialist countries only – by the

Department of Education of the host country. This department covered the expenses of

the teams in the host country (including a little pocket money). Travel costs were paid by

the invited countries. In 1964, the first non-European country took part: Mongolia. In

1965, in the German Democratic Republic, Finland was the first non-socialist country to

participate. The United States of America joined the IMO in 1974 for the first time and in

1977 the Federal Republic of Germany started to attend. In 2009 the 50th IMO will be

held in Germany again (1980 was the only year without an IMO). On the occasion of this

anniversary we present a compilation of all German participants: those from the German

Democratic Republic 1959-1990, from the ‘old’ Federal Republic of Germany 1977-1990

and from ´today's´ Federal Republic of Germany 1991-2008.

Unfortunately, the data collected on the German participants and their professional

careers have several gaps. We have tried to be as accurate as possible and we would like

to thank all former participants, team leaders and deputies, who provided the desired

information. Further completion and corrections are very welcome. Please send this

Introduction

Student teams from the German Democratic Republic (GDR) took part in 29 out of the

31 International Mathematical Olympiads (IMOs) which were held between 1959 and

1990. In 1978 (Romania) and 1981 (USA) the invitations were not accepted for political

reasons. At 19 IMOs, the GDR was represented by 8 students, in 1960 by 7, at 7 IMOs by

6 students, in 1988 by 5, and in 1982 by 4 students. This makes a total of 210

participants of whom 148 were prize winners. But as W. Burmeister took part in 5 IMOs,

S. Heinrich in 4 IMOs, 7 students in 3 IMOs, and 32 students in 2 IMOs, the total is really

157 different students, including 15 girls.

Beginning with the 4th IMO, the participants were selected on the basis of their results

at the ´Olympiaden Junger Mathematiker´ – OJM (Olympiads of Young Mathematicians)

in the GDR. These competitions had been organised by the Ministry of People’s

Education, the Mathematical Society and the Central Council of ´Freie Deutsche Jugend’

(youth organisation of the GDR) since the school term 1962/63. In 1965, a regular 17-

gon with ruler and compass was introduced as the logo of the OJM, referring to a youth

achievement of C.F. Gauss. This logo was also used for the IMOs held in the GDR.

The OJM was open to male and female students of the 10-grade polytechnical

secondary schools, the extended secondary schools, the final grades of the vocational

schools, and the special schools and classes under the supervision of the Ministry of

People’s Education and of University and Vocational Education. The competition was

held on four levels:

– School Olympiad for grades 5 to 11/12 (homework test in September),

– Regional Olympiad for grades 5 to 11/12 (1 written test in November),

– District Olympiad for grades 7 to 11/12 (2 written tests on 2 days in February),

– GDR-Olympiad for grades 10 to 11/12 (2 written tests within 3 days in May).

At each level, students could take part in a higher grade than the actual grade they were

in.

6

Based on the results in the GDR-Olympiad, about 50 per cent more candidates than

the IMO team size (1959-1981: 8, 1982: 4, 1983-1990: 6) were selected and – since 1963

– prepared for the IMO at a training camp lasting one to two weeks. During the

following years this preparation was extended. Before the IMO in 1988 there were

courses for two weeks in October, one week in February, two weeks in April and three

weeks in June. Initially, selection of the candidates was based on the results at the OJM

of the current year, but in the course of time the extended preparation made it

necessary to select the trainees on the results of the previous year. To enable the

candidates to prepare at home, the Mathematical Society of GDR and the Ministry of

People’s Education edited 29 booklets and 6 special issues with contest problems and

related theory. The final selection was based on further written tests at the end of the

final training camp.

The Federal Republic of Germany (GER) entered the IMO officially in 1977 in

Yugoslavia after being represented in 1976 by two students and two team leaders as

observers. The initiative for participation was substantially due to Professor Arthur Engel

(U Frankfurt am Main).

The Federal Republic of Germany took part in all 13 IMOs from 1977 to 1990 with

complete teams (regrettably consisting exclusively of boys). That is 8 students from 1977

to 1981, 4 students in 1982 and 6 students from 1983 to 1990. The total number of 84

participants and 76 medallists is represented by 60 different students, as some took part

in more than one olympiad.

The team members were selected from the prize winners of the second round of the

‘Bundeswettbewerb Mathematik’ – BWM (German National Mathematics Competition).

The BWM was initiated in 1970 by the ‘Stifterverband für die Deutsche Wissenschaft’

(Donors´ Association for the Promotion of Science in Germany). The competition consists

of two rounds of 4 problems each to be solved at home and a final mathematical

disputation. It is open to students at all schools leading to the ‘Abitur’ degree, the final

examination qualifying for university entrance.

7

Starting with the second year of participation, the selection of the Federal German

team for the IMO was based on two written tests (in the first year, there was only one

test). Invitations went to all winners of first and second prizes of the second round of the

BWM, who still met the age requirements. The tests were taken at their home schools on

two fixed dates. In later years, invitations were extended to all prize winners of the

second round of BWM and to successful contestants of the maths sector of ‘Jugend

forscht’ (a competition for science) and the Berlin Mathematical Competition.

On the basis of the results of these written tests, the top 16 students were invited to

take part in five training sessions, consisting of four weekends from Friday afternoon to

Monday morning and one final season lasting about one week. In the first years, these

meetings were held at a conference centre in Königstein/Taunus, later on in a youth

hostel in Frankfurt am Main. Since 1983 the final week has been held at the

Mathematical Research Institute in Oberwolfach/Black Forest. During the training

sessions, the students were taught the necessary mathematical knowledge and tools as

well as important problem solving strategies. Furthermore, they had to take several

written tests, their results being used to finally select the IMO team members. The scores

of the first two selection tests held at school were not used for this purpose.

Since 1982, the IMO-team members receive scholarships from the prestigious

‘Studienstiftung des deutschen Volkes’ (German Scholarship Foundation) as soon as they

commence university studies. From the beginning preparation of the team and

participation at the IMO was financed by the Federal Ministry of Education and Research.

As a result of the unification of the two German States since 1991 there is only one

German team at the IMO. Selection begins at the end of the year, when successful

participants of the second round of the ´Bundeswettbewerb Mathematik´, of the

4th round of the ´Mathematik-Olympiaden in Deutschland’ and of ‘Jugend forscht’

(maths sector) are invited to sit two written selection tests in December. These tests are

held simultaneously at their respective schools, supervised by teachers but evaluated

centrally. Based on the results of about 120 to 150 participants, the top 16 are invited to

8

the training sequence, which since 1991 consists of five meetings between February and

June:

– a week meeting in Rostock,

– three weekend courses in Frankfurt am Main,

– a final week at the Mathematical Research Institute in Oberwolfach.

The training sessions are handled by a well-practised team. Longstanding members,

for instance, are Prof. A. Engel (U Frankfurt am Main), Prof. Dr. K. Engel (U Rostock), Prof.

Dr. H.-D. Gronau (U Rostock), Dr. M. Härterich (Wiesloch), Dr. T. Kleinjung (EPF

Lausanne), PD Dr. R. Labahn (U Rostock), Prof. Dr. U. Leck (U Superior, WI, USA), Dr. E.

Müller (Villingen-Schwenningen), Prof. Dr. J. Prestin (U Lübeck), Prof. Dr. E. Quaisser (U

Potsdam), Dipl.-Math. C. Reiher (U Rostock), Dr. H. Sewerin (Ed Hofheim am Taunus).

Mathematical topics as well as problem solving strategies are presented in lectures

and exercises. Extensive literature is given to the students in order to facilitate

independent work between the training sessions. About six written tests determine the

actual IMO team members.

Preparation of the team and participation in the IMO is still fully financed by the Federal

Ministry of Education and Research and the IMO-team members receive a scholarship of

the ´Studienstiftung des deutschen Volkes´.

Abbreviations and explanations

As the form of government and the official names of some countries have changed in

recent years, the full names are used only for the host countries of the IMO, whereas

abbreviations appear in the various tables. The abbreviations are the official IMO

abbreviation, see www.imo-official.org and the table on p. 12.

The students are listed with their school town (former ‘Karl-Marx-Stadt’ always named

‘Chemnitz’) and the school they attended in the respective year. Home towns may be

different from school towns. Name and school are followed by the prize and (in

brackets) the score. Finally, further IMO participation and/or biographical details are

mentioned.

In Germany, children normally start school at the age of six. The final examination

qualifying for university or college entrance (‘Abitur’) is taken after 13 or 12 years.

Regulations for the IMO

Introduction

1 The attached 'permanent' regulations cover matters which should not change from

year to year. If a host country wishes to vary any of these regulations the IMO

Advisory Board (IMOAB) should be consulted.

2 Each year the host country/organizers will need to make regulations stating:

– the place and dates of the IMO;

– the dates of the official program for team leaders;

– the dates of the official program for deputy leaders and teams;

– the date by which official acceptances of invitations to participate must be

received;

– the dates by which participating countries must send other information about

leaders, deputy leaders and teams, and travel plans;

– the date by which problems proposed for the contest must be received;

– the dates on which the contestants will write the two examination papers.

3 The 'Information and Recommendations for IMO Hosts' is intended to help IMO

organizers. Organizers are invited to suggest to the IMOAB other points to add to

this list that would help future organizers.

Regulations for an International Mathematical Olympiad

(This document was approved by the jury of the 35th IMO on July 17, 1994.)

A The aims of the IMO are:

– to discover, encourage and challenge mathematically gifted young people in all

countries;

– to foster friendly relations between mathematicians of all countries;

– to create opportunities for the exchange of information on school syllabuses and

practice throughout the world.

86

B1 Participation in an IMO is by invitation. Each invited country is entitled to send a

team consisting of a leader, a deputy leader and no more than six contestants.

B2 Contestants should not have been formally enrolled and commenced their studies

at a university or at any equivalent post-secondary institution. A contestant's 20th

birthday must be after the day of the second examination paper.

B3 The host country covers all official expenses for the teams, leaders and deputy

leaders, including meals and accommodations for the period of the official

program. Any country whose team, leader or deputy spends extra days in the host

country must meet the full cost of such extra days.

B4 Observers and family members may accompany a leader or deputy leader. Such

observers or family members are responsible for all their own expenses. The host

country may, if necessary, restrict the number of such 'extra' persons.

B5 Each invited country wishing to participate in an IMO must send an official

acceptance to be received by the organizers by the closing date stated.

B6 Each participating country must send to the organizers information as requested by

the dates specified.

C1 Each participating country is expected to submit problems, with solutions, for

consideration by the host country. The problems should, if possible, cover various

fields of pre-university mathematics and be of different degrees of difficulty.

Problems and solutions may be submitted in English, French, German, Russian or

Spanish.

C2 The organizers shall not distribute short listed problems to the participating

students (approved by the jury of the 36th IMO on July 17, 1995 relevant to IMO 95).

D1 The contest will take place on two days. On each day 4½ hours will be allotted for

the examination paper and each day the paper will contain three problems, each

worth 7 points.

D2 The problems will be given to each contestant in her/his own language.

87

D3 Each contestant is to work independently and submit solutions in her/his own

language. Students writing should finish when all others do except for exceptional

circumstances which will be brought to the jury as soon as possible. (Approved by the

jury of the 36th IMO on July 14, 1995)

D4 The only instruments permitted in the contest are writing and drawing instruments.

In particular, books, papers, tables, calculators and computers may not be brought

into the examination room.

D5 Each contestant's solutions are first assessed by her/his leader and deputy leader.

D6 The final scores, unless disputed and referred to the jury by the leaders, are decided

by the coordinators appointed by the organizers. The score for each problem for

each contestant, agreed by the team leader and the coordinators, is recorded and

signed by the team leader and one of the coordinators for that problem.

D7 For each problem the coordination of solutions by contestants in the team from the

host country shall be verified by the team leader of the country which submitted

the problem.

D8 The numbers of first, second and third prizes will be approximately in the ratio 1:2:3.

The total number of these prizes will not be more than half of the number of

contestants.

D9 Special prizes may be awarded for solutions considered outstanding by the jury.

D10 Each contestant who has not received any one of the first, second or third prizes

will receive a certificate of honorable mention if she/he has scored full points (7) for

at least one problem.

D11 Each contestant shall receive a certificate of participation.

E1 The jury consists of all team leaders and a chair and a deputy chair appointed by

the organizers. A leader may be replaced by her/his deputy. Observers may attend

meetings of the jury only with the permission of the chair, but are not entitled to

speak or to vote. Deputy leaders may attend meetings of the jury after the contest,

but shall have no right to speak nor to vote.

88

E2 The chair and each leader have one vote. A motion shall be carried by a simple

majority of votes. In the event of a tie, the chair shall have a casting vote.

E3 The jury may appoint sub-committees to consider specific matters.

E4 The meetings of the jury will be conducted principally in English. Whenever

requested, and, in particular, before any vote, interpretations will be given in

French, German, Russian, and any other language that the host country deems to

be desirable.

E5 When a problem has been selected for the contest the jury shall first approve an

English language version. Final versions in English, French, German, Russian and

Spanish shall be approved by the jury.

E6 Before the contest, the jury:

– verifies that all contestants comply with the prescribed conditions for par-

ticipation;

– selects the contest problems from among the submitted proposals on the basis

of a preliminary selection made by the Problem Selection Committee appointed

by the organizers;

– approves the translations of the chosen problems into all required languages.

E7 The jury considers any written questions raised by any contestant during the first

half hour of each of the two examinations, and decides on the replies to be given.

E8 After the contest, the jury:

– considers any dispute which may have arisen during coordination concerning the

points proposed for a solution and decides the appropriate number of points to

be awarded;

– approves the scores for all contestants;

– decides the award of first, second and third prizes;

– considers and makes decisions on all proposals to award special prizes; receives a

report from the IMOAB;

– considers any matter raised concerning future IMOs.

89

Informations and recommendations for IMO Hosts


The IMO jury commends the following points to IMO host countries.

1 It is the accepted custom to invite to an IMO a team from each country that has

participated in any of the three previous IMOs.

2 Where a country has participated in none of the three previous IMOs, a host

country may write to determine if an invitation would be welcome.

3 Where two countries that have each participated in past IMOs unite to form one

country (as happened with the two Germanys) one team from the united country

should be invited.

4 Where a country that has participated in past IMOs breaks up to become a number

of separate countries, each of the new countries should be invited to send a team

to the IMO, but no invitation should be sent to the former country that has now

been divided; there should not be 'double representation'. However, it is realized

that financial and accommodation constraints may make it difficult for a host

country to follow this guideline.

5 A 'new' country that wishes to participate in future IMOs should apply to the

secretary of the IMOAB. (Any inquiries received by leaders or others should be

directed to the secretary of the IMOAB). The usual procedure will be for a 'new'

country to first send an observer to the next IMO, paying in full all charges for the

observer's transport, accommodation, food, etc., and to enter a team for the

subsequent IMO. Thus, when the secretary receives an application, he will contact

the hosts of at least the next two IMOs to ensure that they can meet the above

program. The next host must be able to accept the observer and the second host

must be able to accept and accommodate the team. All other formally accepted

host countries will be informed of the application at the same time.

6 If a host finds itself uncertain of the countries or territories that should be invited to

send teams to the IMO the IMOAB should be asked for advice.

90

7 A country's delegation normally consists of a leader and deputy and the team,

usually consisting of 6 pupils.

8 Official invitations should be sent to members of the IMOAB. Host countries should

meet all expenses (apart from travel to the IMO) of IMOAB members who are not

team leaders or deputies.

9 It is accepted custom that the IMOAB meets on at least two occasions during the

IMO. The first meeting should be held on the day before leaders arrive for the IMO.

10 The host country must ensure that the working conditions for the students when

they are writing the solutions to the problems are satisfactory, with adequate

heating and ventilation. In addition it is essential that the arrangements are such

that the students are not encouraged to cheat. In general there should be no more

than one student from each country in any examination room.

11 As more countries take part in IMOs the range of languages and scripts used

increases. Organizers are advised to seek an interpreter/coordinator for each

language used in the IMO who is competent to check that the translation of the

problems is accurate and that the students' scripts are being fairly assessed.

12 At least half a day's free time should be allowed for leaders before the first jury

meeting at which the selection of problems is discussed.

13 When issuing an official invitation a potential host country should make certain that

sufficient funds are available to meet the cost of the IMO.

14 Host countries are advised to consider accident and health insurance for par-

ticipants and to inform participating countries before the IMO of actions taken.

15 It is helpful if the host country informs participating countries of the arrangements

for accommodation of teams and deputies. If possible the deputy should be housed

near to her/his team.

16 At the conclusion of an IMO leaders should be provided with a full set of scores for

all contestants and countries and a full set of addresses of leaders and deputy

leaders.

91

17 It is very helpful if a host country prepares a report on its IMO, noting any dif-

ficulties or problems encountered, and sends this report to the IMOAB and to the

next year's host.

18 It is essential that, before they leave home for the IMO, leaders are informed of a

telephone number for use in emergency.

Responsibilities for IMO leaders


The leader should be sufficiently involved in mathematics to carry out the following

responsibilities. (This statement was approved by the jury of the 36th IMO on July, 1995.)

1 Inform the participants, the deputy and other persons involved, of the regulations

for the Olympiad. In particular the leader has to inform the participants that the use

of notebooks, mathematical tables, calculators, computers, etc. is not allowed.

2 Ensure that her/his country submits problems to the Problem Selection Committee

of the host country. If possible each problem should be accompanied by a

description of its creation.

Ensure that the proposed problems and their solutions are kept secret.

3 Submit to the Problem Selection Committee of the IMO an English version of all the

problems used in contests (national or regional) arranged by her/his country and

held after the previous IMO.

4 Attend all the meetings of the jury of the IMO and take part in its work.

5 Inform the jury if any short listed problem is already known to her/him, her/his

team or other people involved in the preparation of the team.

6 Ensure the preparation of an accurate translation of the chosen problems into the

contestants' own language for the use of her/his team.

7 Ensure that the deadlines set by the host country are met.

8 During the IMO supply the representative of the next host country with up to date

addresses of institutions and contact persons to whom documents and invitations

should be sent.

92

9 Inform her/his national committee of decisions taken by the jury during the IMO.

Responsibilities for deputy leaders

(Approved by the jury of the 36th IMO on July 17, 1995)

1 The deputy leader should be sufficiently involved in mathematics to help the leader,

and in case of an emergency to replace the leader. In particular, the deputy leader

should:

– assist the leader with the evaluation of the team's solutions to the problems

– assist the leader during the coordination of the problems.

Additional responsibilities include:

2 Inform the participants of the regulations pertaining to the examination.

3 Supervise the conduct and welfare of the team during the activities of the IMO.

Regulations & responsibilities of the IMO Advisory Board (IMOAB)

(This document was approved by the jury of the 35th IMO on July 17, 1994)

General Principles

1 The advisory board is a committee whose members are nominated by the jury of the

IMO and appointed by ICMI. Members of the IMOAB have, or have had a role directly

linked to the IMOs, such as leader, deputy, or organizer of an IMO.

2 The IMOAB is an advisory body in which propositions concerning the functioning of

IMOs are discussed. The IMOAB has no power to make decisions; all decisions are

made by the IMO jury. Between IMOs the IMOAB acts on behalf of the jury, and

reports any decisions taken to the jury at the next IMO.

3 The IMOAB also has the responsibility of maintaining relations between IMOs and

other international organizations with the object of promoting the popularization of

IMOs.

4 The IMOAB is responsible to the jury for all its actions and each year, during the

IMO, shall report to the jury on actions it has taken.

93

Constitution and meetings

5 The membership of the IMOAB consists of a chair, a secretary, three other members

nominated by the jury and appointed by ICMI; and representatives of the host

countries for the last, the present and the two following IMOs.

(This revision of the statement of §5 was approved by the jury of the 36th IMO on July 17, 1995.)

6 The period of service for appointed members is four years. The 'appointment year'

is from the end of one IMO to the end of the next. Nominations for membership of

the IMOAB must be given to the secretary at the end of an IMO; the jury votes to

select new members during the next IMO.

In making appointments it is desirable that the chair and secretary should not give

up their posts in the same year.

If possible the chair and secretary should have been members of the IMOAB before

taking up their offices.

7 The IMOAB shall meet at least twice during each IMO (the first meeting being at the

beginning of the IMO), and at other times if necessary.

8 The chair and the secretary of the IMOAB may attend meetings of the IMO jury, but,

unless they are leaders, shall not be entitled to vote.

Responsibilities

A Concerning the functioning of IMOs

Bildung und Begabung e.V. The association Bildung und Begabung e.V. was founded in 1985 on the initiative of the Stifterverband für die Deutsche Wissenschaft (Donors' Association for the Promotion of Science in Germany). It is a non-profit making, non-partisan organisation. Its offices are located in Bonn.

The association's objectives are based (1) on the fact that there are gifted and able young people within our educational system who wish to work in their own special fields beyond the limits of their particular course of education and (2) on the knowledge that for optimal development even the most talented require extensive support.

Measures which supplement the voluntary extra-curricular courses and activities already available at existing educational establishments must be developed to en-courage these young people's talents and interests to grow. Such measures should offer young people an opportunity to work according to their own inclination, capability and speed.

The association's activities are concentrated primarily on 1) national competitions in mathematics and foreign languages. These are run in close

co-operation with the individual German federal states. Furthermore, the association is responsible for the selection, preparation and participation of a national team to take part in the annual International Mathematical Olympiad;

2) the organisation of residential academic summer programmes for highly gifted and motivated upper secondary pupils. Since 1988 the Deutsche SchülerAkademie (German Pupils' Academy) has developed into the major effort to promote talented adolescents in Germany;

3) a documentation and information service dealing with all aspects of research on talent development and support for the gifted such as programmes within Germany and abroad; grants, competitions and prizes; national and international organisations, conferences, vocational training; experts on talent research, advice and support; publications and bibliographies;

4) initiatives to enhance and promote knowledge about talent development and educational approaches in this domain by means of specialist conferences, publi-cations and pilot studies;

The association and its projects are financed predominantly by the Federal Ministry for Education and Research and by the Stifterverband. A few individual projects are funded by other foundations or sponsors.
