Constantin Fahlberg (22 December 1850 in Tambov – 15 August 1910 in Nassau) discovered the sweet taste of anhydroorthosulphaminebenzoic acid in 1877–78 when analysing the chemical compounds in coal tar at Johns Hopkins University for Professor Ira Remsen (1846–1927). Later Fahlberg gave this chemical "body" the trade name Saccharin.
