derivatives, Fahlberg noticed that the rolls tasted initially sweet but then bitter. Since his wife tasted nothing strange about the rolls, Fahlberg tasted his fingers and noticed that the bitter taste was probably from one of the chemicals in his lab. The next day at his lab he tasted the chemicals that he had been working with the previous day and discovered that it was the oxidation of o-toluenesulfonamide he had tasted the previous evening. He named the substance

and he and his research partner Remsen published their finding in 1880. Later Remsen became angry after Fahlberg, in patenting saccharin, claimed that he alone had discovered saccharin. Remsen had no interest in the commercial success of saccharin, from which Fahlberg profited, but he was incensed at the perceived dishonesty of not crediting him as the head of the laboratory. Throughout his academic career, Remsen was known as an excellent teacher, rigorous in his expectations but patient with the beginner. "His lectures to beginners were models of didactic exposition, and many of his graduate students owe much of their later success in their own lecture rooms to the pedagogical training received from attendance upon Remsen's lectures to freshmen." He was elected as a member to the
