In 1921, Sadie Tanner Mossell Alexander became the first black woman in the U.S. to obtain a Ph.D. Despite her academic achievements, she had difficulty finding employment in Philadelphia and went to work for the black-owned North Carolina Mutual Life Insurance Company in Durham, remaining there for two years. In 1923, shortly after Raymond Alexander was admitted to the Bar and opened his practice, she returned to Philadelphia to be married. The following year, in the fall of 1924, she entered the University of Pennsylvania Law School. She became the first black woman to graduate from that institution and the first black woman admitted to the Pennsylvania Bar in 1927.
