Ira Remsen, American chemist and academic (born 1846)

Ira Remsen was an American chemist who introduced organic chemistry research and education in the United States along the lines of German universities where he received his early training. He was the first professor of chemistry and the second president of Johns Hopkins University. He founded the American Chemical Journal, which he edited from 1879 to 1914. The discovery of saccharin was made in his laboratory by Constantine Fahlberg who worked in collaboration with Remsen but patented the synthesis on his own, earning the ire of Remsen.
