# Sheila Moriber Katz

Sheila Sue Moriber Katz (February 1, 1943 – September 10, 2023) was an American pathologist and writer, dean of the Hahnemann University School of Medicine, and co-founder of the School of Public Health at Drexel. She is sometimes described as the first person to see the bacterium Legionella pneumophila, which causes Legionnaires' disease.

## Early life and education

Moriber was born in Brooklyn's Bensonhurst neighborhood, the daughter of Joseph Moriber and Muriel Goldfinger Moriber. Her father was a lawyer and real estate developer. She graduated from Cornell University in 1962 at the age of 19. She earned a medical degree at Duke University School of Medicine in 1966. In 1990 she earned an MBA at the Wharton School.

## Career

Katz was a pathologist and professor at Hahnemann University School of Medicine beginning in 1974. She reached full professor status in 1981, and in 1993 became senior associate dean. She was director of the microscopy laboratory at Hahnemann, and co-founder of the School of Public Health there. She was president of the Philadelphia County Medical Society, and of the Duke University Medical School Alumni Council.
Katz studied Legionnaire's disease after a deadly outbreak in Philadelphia in 1976. She may have caught the disease herself, from handling a sample of infected lung tissue. She was the first scientist to see the bacterium Legionella pneumophila. Newsweek magazine included Katz in a list of 100 "unsung heroes" in 1986. In 1993 she was honored by the Girl Scouts of Greater Philadelphia as a woman achiever in science.
In the 1990s, Katz led the White House Commission on Complementary and Alternative Medicine. She was executive officer of the Allegheny Health Education and Research Foundation in Philadelphia. She founded her own business, NewMedicine, in 2000. Katz also wrote poetry.
