More than any other individual, U.S. Supreme Court Justice Ruth Bader Ginsburg “is responsible for eliminating sex discrimination from American law,” fellow Justice Elena Kagan said in a lecture Monday night that paid homage to Ginsburg’s fight for women’s equality.

Kagan noted that more than a quarter of a century separated her own appointment to the court from the appointment of the first woman justice, Sandra Day O’Connor, and she credited O’Connor and Ginsburg for paving the way for women.
