Two trailblazing Supremes did not sing but they worked in harmony to help reshape America.
Sandra Day O'Connor and Ruth Bader Ginsburg were the first two female justices on the U.S. Supreme Court. That they became close friends shows that birth and background do not prefigure destiny.
Hailing from rural Arizona, O'Connor grew up on a ranch and cleaved to conservative values. Ginsburg was a proud liberal from Brooklyn — the same New York City borough as legendary rapper Notorious B.I.G., hence her nickname, "Notorious RBG."
In the late 20th century, the two women worked to empower women and also opened the door to an institution that had been male-dominated for centuries. Their unlikely friendship is the subject of Linda Hirshman's bestselling book "Sisters in Law," which was adapted for the stage by Jonathan Shapiro.

The play opens Saturday in St. Paul's Six Points Theater, just days after Supreme Court Justice Amy Coney Barrett's controversial visit to the University of Minnesota. (Barrett replaced Ginsburg.)
Four of the six women to ever serve on the nation's highest court have been three-named wonders, with Ketanji Brown Jackson being the latest justice. Outliers are Justices Sonia Sotomayor and Elena Kagan. The question arises, do women have to have three names to be on the Supreme Court?
"Gosh, it does seem like it when you put it that way," said Patty Mathews, who plays O'Connor in "Sisters."
"Of course, they would argue for the freedom of any names," said Laura Esping, who plays Ginsburg.
