John Napier is most remembered as the inventor of logarithms and Napier's bones, and for popularizing the use of the decimal point. Napier's birth place, Merchiston Tower, Edinburgh, Scotland, is now part of Edinburgh Napier University. After dying of gout, Napier was buried in St Cuthbert's Church, Edinburgh.
