Alexander's Family Legacy Alexander came from a family with a rich legacy. Her maternal grandfather, Benjamin Tucker Tanner was appointed the bishop of the African Method Episcopal Church. Her aunt, Halle Tanner Dillon Johnson was the first African-American woman to receive a license to practice medicine in Alabama. And her uncle was internationally acclaimed artist Henry Ossawa Tanner. Her father, Aaron Albert Mossell, was the first African-American to graduate from the University of Pennsylvania Law School in 1888. Her uncle, Nathan Francis Mossell, was the first African-American physician to graduate from the University of Pennsylvania Medical School and co-founded the Frederick Douglass Hospital in 1895. Early Life and Education Born in Philadelphia in 1898, as Sarah Tanner Mossell, she would be called Sadie throughout her life. Throughout her childhood, Alexander would live between Philadelphia and Washington D.C. with her mother and older siblings. In 1915, she graduated from the M Street School and attended the University of Pennsylvania School of Education. Alexander graduated with a bachelor's degree in 1918 and the following year, Alexander received her master's degree in economics. Awarded the Francis Sergeant Pepper fellowship, Alexander went on to become the first African- American woman to receive a Ph.D. in the United States. Of this experience, Alexander said “I can well remember marching down Broad Street from Mercantile Hall to the Academy of Music where there were photographers from all over the world taking my picture.” After receiving her Ph.D. in economics from University of Pennsylvania's Wharton School of Business, Alexander accepted a position with the North Carolina Mutual Life Insurance Company where she worked for two years before returning to Philadelphia to marry Raymond Alexander in 1923. The First Female African-American Lawyer Soon after marrying Raymond Alexander, she enrolled in the University of Pennsylvania's Law School where she became a very active student, working as a contributing writer and associate editor on the University of Pennsylvania Law Review. In 1927, Alexander graduated from the University of Pennsylvania School of Law and later became the first African-American woman to pass and be admitted to the Pennsylvania State Bar. For thirty-two years, Alexander worked with her husband, specializing in family and estate law. In addition to practicing law, Alexander was served as Assistant City Solicitor for the City of Philadelphia from 1928 to 1930 and again from 1934 to 1938. Truman's Committee of Human Rights The Alexanders were active participants in the Civil Rights Movement and practiced civil rights law as well. While her husband served on the city council, Alexander was appointed to President Harry Truman's Committee of Human Rights in 1947. In this position, Alexander helped to develop the concept of a national civil rights policy when she co-authored the report, "To Secure These Rights." In the report, Alexander argues that Americans—regardless of gender or race—should be granted the opportunity to improve themselves and in doing so, strengthen the United States. Later, Alexander served on the Commission on Human Relations of the City of Philadelphia from 1952 to 1958. In 1959, when her husband was appointed as a judge to the Court of Common Pleas in Philadelphia, Alexander continued to practice law until her retirement in 1982. She later died in 1989 in Philadelphia.
