Probstein, J. G. (Jacob G.), 1894-

Jacob G. Probstein (1894-1993) received his bachelor's and medical degree (1917) from Loyola University in Chicago. He served his internship at New Grant Hospital in Chicago (1917-1918). He was assistant in medicine at St. Louis University in 1919. He began his medical practice in St. Louis in 1922. He had a long association with both Jewish Hospital in St. Louis and Washington University School of Medicine. He also was associated with other hospitals, Barnes Hospital (1941-) and Homer G. Phillips among others.

At Jewish Hospital he served first as assistant in surgery in Jewish Hospital dispensary (1919-1921), assistant in surgery in Jewish Hospital (1922-), and later as surgeon and chief of surgery, 1946-1953. While he was also company physician to Famous Barr, Co. in the 1920s, he interested the May family in supporting research at Jewish Hospital. This led to a group being formed around Michael Somogyi in pancreatitis research and other diseases and led to the Somogyi test, a test for blood amylase. Jacob Probstein himself was a member of Somogyi's group which made such sigificant advances in the research and treatment of pancreatitis. Probstein's contributions to the medical literature are published in dozens of papers and two books.
