Meaning
diminutive of Sarah, from Hebrew sarah, "lady, princess, noblewoman"
The story
Sadie began as an English affectionate form of Sarah, whose Hebrew meaning includes "lady," "princess" and "noblewoman." The name also escaped from Al Capp’s Li’l Abner: his invented Sadie Hawkins Day became a nationwide school and college custom. The affectionate form also belongs to a formidable professional life: that of Sadie Tanner Mossell Alexander. She earned an economics doctorate at Penn in 1921, becoming one of the first three Black women in the United States to receive a PhD. Yet finding work in Philadelphia proved difficult, and she spent two years with the Black-owned North Carolina Mutual Life Insurance Company in Durham. She then entered Penn Law, becoming its first Black woman graduate and the first Black woman admitted to the Pennsylvania Bar in 1927. Estate and family law became part of her practice. Her career makes the turn tangible: an economist who struggled to find work returned to university and entered a different profession.
