Nicholas Ernestovich Geacintov (to his 60th birthday)

O11 November 9, 1995, foreign member of the Russian Academy of Sciences Professor of Chemistry of the New York University Nicholas Ernestovich Geacintov will be sixty years of age.

N. E. Geacintov was born in t935 in Albi (France). In 1957 he graduated from Syracuse University (USA) and in 1961 he got a Ph.D. degree in physical chemistry and the chemistry of polymers; he began his sciemific career working at the Brooklyn Polytechnic Institute, where he carried out studies in the field of photochemistry. In 1963, Nicholas Ernestovich began working at the New York University as a member of the laboratory of investigation of radiation and solids at the Department of Physics; later he became a Professor at the Department of Chemistry, and since 1975 he has been the Head of the Medical School at the University.

N. E. Geacintov is a prominent physical chemist famed for his works in the field of spectroscopy of molecular crystals, photophysics, and photochemistry. He was among the first to discover the effect of a magnetic field on the intensity of slow fluorescence in crystals and liquid solutions and explained this effect by spin prohibitions in triplet annihilation processes. N. E. Geacintov is the author of fundamental works dealing with the chemistry of excited molecules, photoionization in crystals, photochemistry of molecules of biologically active compounds, and the transfer of energy in photosynthesizing systems. In recent years Professor N. E. Geacintov has been engaged in studies in the field of photostimulation of the interaction of polycyclic carcinogens with nucleic acids, aimed at the development of new chemical methods of anticarcinogenesis. N. E. Geacintov is the author of more than 200 papers and 3 patents.

N. E. Geacintov is a member of the American Physical and Chemical Societies and a number of other national scientific societies, President of the American Society of Photobiology, coordinator of some national scientific programs, and a member of the National Committee on the nomination of candidates for the Nobel Prize.

Achievements in the field of physical chemistry brought N. E. Geacintov world fame. He is a Professor of several European institutes, and in 1994, he was elected a foreign member of the Russian Academy of Sciences.

The Editorial Board and the Editorial Staff of the Russian Chemical Bulletin heartily congratulate N. E. Geacintov on his sixtieth birthday.
