Maj. Gen. Marcia Anderson might never have gotten involved with the U.S. Army if she hadn’t needed a science credit at Creighton University in Omaha, Neb. She was wandering through a gym considering booths advertising classes when she saw one for military science. She asked the man attending the booth whether the class counted as a science credit. It did. About 30 years later, Anderson stood in front of soldiers, political officials and area residents and was promoted as the first black woman to become a major general in the Army.
