March 26th marks the 85th birthday of former United States Supreme Court Justice Sandra Day O’Connor, the first female jurist appointed to that position.

Here are three things you might not know about Sandra Day O’Connor.

One: She grew up on a cattle ranch near El Paso, Texas before attending Stanford University and earning her bachelor’s and law degree. While at Stanford, she briefly dated classmate William Rehnquist, who would go on to be the Chief Justice of the Supreme Court.

Two: She was nominated to the Supreme Court by President Ronald Reagan in 1981, and confirmed by the Senate on a 99-0 vote.

Third: The federal courthouse in Phoenix, Arizona is named after her, and she received the Presidential Medal of Freedom from President Barack Obama in 2009.

Our question: Sandra Day O’Connor served on the Supreme Court from 1981 through 2006. Who did she replace on the Supreme Court and who replaced her?
