Martha Wollstein

Died 30 Sep 1939 at age 70 (born 21 Nov 1868).American physician and pediatric pathologist. Her first experimental work involved infant diarrhea and confirmed earlier studies relating the dysentery bacillus to the disease. At the Rockefeller Institute of Medical Research, she collaborated on the first experimental work on polio in the U.S., worked on an early investigation of pneumonia and developed, with Harold Amoss, a method for preparing antimeningitis serum. She also pioneered in early research on mumps, indicating, though not proving, its viral nature. After 1921, Wollstein investigated pediatric pathology at the Babies Hospital, especially jaundice, congenital anomalies, tuberculosis, meningitis, and leukemia. In 1930, she was the first female member of the American Pediatric Society.
