Otto Hönigschmid (13 March 1878 in Hořovice 14 October 1945 in Munich) was a Czech/Austrian chemist. He published the first widely accepted experimental proof of isotopes along with Stefanie Horovitz. Throughout his career he worked to precisely define atomic weights for over 40 elements, and served on committees with the purpose of adopting internationally agreed upon values. After his home and laboratory in Munich were destroyed in World War II, he committed suicide in 1945.
