Julius Stieglitz

Julius Oscar Stieglitz (May 26, 1867 – January 10, 1937) was an American chemist of German Jewish origin. He was a teacher and organic chemist with a major interest in pharmaceutical and medicinal chemistry. He is known for the Stieglitz rearrangement, a rearrangement reaction in organic chemistry which commonly involves the formation of imines from hydroxylamines through a carbon to nitrogen shift, comparable to the key step of a Beckmann rearrangement. During the early stages of his career, he worked for Parke, Davis & Co. in Detroit as a toxicologist. After attending private and public schools in New York during his early years, both he and his twin brother Leopold were sent to Germany for their higher education. He went to the Gymnasium in Germany and studied at the University of Berlin, where he received his PhD in chemistry in 1889 with Ferdinand Tiemann. Following a short period of study with Victor Meyer at Göttingen, he returned to the U.S. in 1890. In 1892 Stieglitz started working at the University of Chicago, where his whole career until his retirement took place. Julius and his twin brother Leopold were born in Hoboken, New Jersey on May 26, 1867, to Edward Stieglitz (1833–1909) and Hedwig Ann Werner (1845–1922). His elder brother was the photographer Alfred Stieglitz. He married Anna Stieffel on August 28, 1891.
