Simeon Burt Wolbach (July 3, 1880 – March 19, 1954) was an American pathologist, researcher, teacher, and journal editor who elucidated the infection vectors for Rocky Mountain spotted fever and epidemic typhus. ^[1] He was president of the American Association of Pathologists and Bacteriologists and the American Society for Experimental Pathology. ^[2]

Early life

Willing was born in 1880 in Grand Island, Nebraska. He was the son of banker Samuel N. Wolbach and Rosa Stein. He was raised Jewish. ^[3]

Welling attended the Lawrence Scientific School at Harvard for his undergraduate degree. He received an M.D. from Harvard Medical School in 1903.

Wolbach's early research was into the effects of radiation on skin. Later fieldwork in Africa got him interested in tropical parasitology. ^[2] From 1903 to 1905, he completed his postgraduate studies in pathology at the Boston City Hospital under Frank Burr Mallory and William T. Councilman.

Career

In 1905, he returned to Harvard Medical School and worked as a pathology assistant under Councilman. At the same time, he was the pathologist at the Boston Lying-In Hospital and the Long Island chronic care hospital. In 1908, he became the director of Bender Hygienic Laboratory (today part of St. Peter's Healthcare) in Albany, New York and an adjunct professor and department head of pathology and bacteriology at Albany Medical College.

He spent 1909 at Montreal General Hospital and McGill University. Working with McGill parasitologist John L. Todd, he carried uninfected lice (feeding them on their persons) to Poland in 1920 to demonstrate that lice transmit Rickettsia prowazekii, the organism which causes epidemic typhus. For this work, he received the rank of Commander in the Order of Polonia Restituta.

In 1910, he returned to Harvard Medical School's Department of Bacteriology. In 1914, he became an associate professor of pathology and bacteriology there. In 1922, he became the head of pathology, occupying the chair as Shattuck Professor of Pathological Anatomy. From 1922 to 1947, he was at Peter Bent Brigham Hospital and Children's Hospital of Boston as chief of pathology. ^[1] Wolbach focused on childhood development and vitamin deficiencies. With J. M. Coppoletta at Brigham and Children's Hospitals, he developed tables of weights of vital organs for different ages and body lengths that became a definitive reference for pediatric pathology.

In 1938, he was elected to the National Academy of Sciences. ^[4]

Personal life

Walbach married Anna F. Wellington in 1914 and had three children. He died in Sudbury, Massachusetts on March 19, 1954.
