Profile of Kotaro Katsura – the founder
Kotaro Katsura, a grandchild of Taro Katsura who was the 11th, 13th and 15th prime minister of Japan, held a key position as a duke and member of the House of Lords until the late 1940s.
After graduating at the Faculty of Pharmaceutical Sciences of Tokyo Imperial University (now known as the University of Tokyo), he completed his doctorate studies, specialising his thesis on the subject of structure elucidation of the toxic component lycorine contained in cluster amaryllis (lycoris radiata)*. In the laboratory built in the backyard of his home in Mita, Minatoku, Tokyo, he started synthesising saccharin, an artificial sweetener, by applying the organic synthesis technology. This laboratory paved the way for Katsura Chemical Co., Ltd.
