Justice Ruth Bader O'Connor? A lawyer would be ill-advised to refer to a U.S. Supreme Court justice, or any judge for that matter, by the wrong name. But each time Justice Ruth Bader Ginsburg joined courts in which only one other woman was serving at the time — the Supreme Court in 1993 and the U.S. Court of Appeals for the D.C. Circuit in 1980 — that's exactly what happened.

"The idea of two was too much to contemplate," Ginsburg said of her early days on the D.C. Circuit, earning laughs as she shared her experiences during a discussion last week about women and the District of Columbia's federal courts. The event, which was so crowded some attendees had to sit on the floor, featured a panel of pioneering women from across the D.C. court system and private practice.
