Ada Lois Sipuel Fisher, whose lawsuit in the 1940s opened the University of Oklahoma Law School to black students, died Wednesday in Oklahoma City. She was 71.
In 1946, Ms. Fisher became the first black to apply for admission to the university. It took two rulings from the U.S. Supreme Court to open the law school to blacks and to eliminate "colored" seating in class.
Ms. Fisher was represented in her lawsuit by Thurgood Marshall, who later was a Supreme Court justice.
She graduated from the law school in 1951 and earned a master's degree from the university in 1968. She was named to the university's Board of Regents in 1992.
