Marriage to Charles Jacobs

On September 12, 1951, Lillian Baumbach married Charles Jacobs, an event that marked a significant personal milestone following her landmark professional achievement earlier that same year. By the time of her wedding, Lillian had already distinguished herself as the first woman in the United States to earn and hold a master plumber's license, a rare accomplishment that set her apart from virtually every other bride of her generation.

The marriage represented the blending of Lillian's personal and professional life during a pivotal era of postwar America, when women were largely expected to relinquish careers upon marriage. Lillian, however, continued her work in the plumbing trade under her new married name, becoming known professionally as Lillian Baumbach Jacobs.

While detailed records of the ceremony itself are limited, the date is preserved through family and oral history accounts, including retrospectives on her life published decades later. Her ability to maintain her trade career alongside her marriage and domestic life challenged the prevailing social norms of the 1950s, which typically discouraged married women from working outside the home, particularly in physically demanding, male-dominated fields such as plumbing.

This union with Charles Jacobs also explains the surname by which she became most widely known in later historical accounts: Lillian Baumbach Jacobs, the pioneering tradeswoman.
