Irene Morgan worked at the Baltimore-based aircraft manufacturer Glenn L. Martin Company, assigned to the production line of the B-26 Marauder. In the summer of 1944 she came home to Virginia on the Greyhound bus to visit her mother, but was arrested on the return trip to Baltimore for refusing to move to the Colored section. The NAACP Legal Defense Fund took the case and planned to use it to challenge segregation rules on interstate transportation. In 1946, the Supreme Court, in Morgan v. Virginia, held that segregation on interstate buses was illegal.
