Lillian Baumbach Jacobs

Lillian Baumbach Jacobs (1930-2000), from Arlington, Virginia, was a plumber.

In 1951, at age 21, she became the first American woman to earn a master’s license in plumbing.

She had graduated in 1947 from Washington-Lee High School and seems to have learned the basics of plumbing by assisting in her father's plumbing business. She went on to become president of the business until her retirement in 1989.

She made appearances on television shows, in magazines, and as a pin-up girl for an infantry company during the Korean War.

She died of leukemia on January 31, 2000, at the age of 70.
