Vincent du Vigneaud (May 18, 1901 – December 11, 1978) was an American biochemist. He was recipient of the 1955 Nobel Prize in Chemistry "for his work on biochemically important sulphur compounds, especially for the first synthesis of a polypeptide hormone," a reference to his work on the peptide hormone oxytocin.

Biography

Vincent du Vigneaud was born in Chicago in 1901, the son of French inventor and mechanic Alfred du Vigneaud and Mary Theresa. He studied at the Schurz High School and completed secondary education in 1918. His interest in sulfur began when he entered high school and his new friends invited him to run chemical experiments on explosives using sulfur. During World War I, senior students were made to work on farms, and Vigneuad worked near Caledonia, Illinois. There he became an expert in milking cows, which inspired him to become a farmer. However, his elder sister, Beatrice, persuaded him to take up chemistry at the University of Illinois at Urbana-Champaign, after which he enrolled in the chemical engineering course. His interest was aroused by lectures of Carl Shipp Marvel and Howard B. Lewis, whom he remembered as "extremely enthusiastic about sulfur." With little support from the family, he found odd jobs to support himself. After receiving his MS in 1924 he joined DuPont.

He married Zella Zon Ford, whom he met on June 12, 1924 while working as a waiter during his university course. During the fall of 1924, Marvel found him a job as an assistant biochemist at the Philadelphia General Hospital that helped him to teach clinical chemistry at the Graduate School of Medicine, University of Pennsylvania. Marvel would pay for the trip to Pennsylvania in exchange for Vigneaud's preparation of 10 pounds of cupferron. Resuming his academic career in 1925, du Vigneaud joined the group of John R. Murlin at the University of Rochester for his PhD thesis. He graduated in 1927 with his work The Sulfur of Insulin.

After a post-doctoral position with John Jacob Abel at Johns Hopkins University Medical School (1927–1928), he traveled to Europe as National Research Council Fellow in 1928–1929, where he worked with Max Bergmann and Leonidas Zervas at the Kaiser Wilhelm Institute for Leather Research in Dresden, and with George Barger at the University of Edinburgh Medical School. He then returned to the University of Illinois as a professor.

In 1932 he started working at the George Washington University Medical School in Washington, D.C. and in 1938 at the Cornell Medical College in New York City, where he stayed until his emeritation in 1967. Following retirement, he held a position at Cornell University in Ithaca, New York.

In 1974 du Vigneaud suffered a stroke which forced his retirement. He died in 1978, one year after his wife's death in 1977.

Scientific contributions

Vigneaud's career was characterized by an interest in sulfur-containing peptides, proteins, and especially peptide hormones. Even before his Nobel-Prize-winning work on elucidating and synthesizing oxytocin and vasopressin via manipulating the AVP gene, he had established a reputation from his research on insulin, biotin, transmethylation, and penicillin.

He also carried out a series of structure-activity relationships for oxytocin and vasopressin, perhaps the first of their type for peptides. That work culminated in the publication of a book entitled A Trail of Research in Sulphur Chemistry and Metabolism and Related Field.

Honours

Vigneaud joined Alpha Chi Sigma while at the University of Illinois in 1930. He received the 1955 Nobel Prize in Chemistry "for his work on biochemically important sulphur compounds, especially for the first synthesis of a polypeptide hormone," a reference to his work on the peptide hormone oxytocin.
