Ira Remsen

Born 10 Feb 1846; died 4 Mar 1927 at age 81. American chemist who codiscovered saccharin. He taught chemistry at Johns Hopkins University from 1876 (where he became its second president 1901-13). He introduced advanced laboratory instruction using teaching methods he had learned in Germany under Rudolph Fittig. Remsen specialized in the benzene ring and related groups. With Constantin Fahlberg, a student working under his direction, he first synthesized orthobenzoyl sulfimide (1879). Fahlberg accidentally discovered its intensely sweet taste by touching his fingers to his lips while unknowingly having a few grains on them. The compound was patented and marketed under the trade name “saccharin.”
