When the first game of the 2016 World Series begins on Tuesday night, every player on the field will be, as has always been the case with Major League Baseball, a man. But female ballplayers aren’t just the stuff of fiction or even wartime necessity.

A New York Times article from that year explained that the Female Giants comprised 32 players who competed against one another on two teams, the Reds and Blues. Historian Michael Carlebach notes in his book Bain’s New York that it seems likely that the Giants were created by John McGraw, manager of the MLB’s Giants, then a New York team. The young women of the team, mostly high school students, were a curiosity and perhaps seen by many as a mere stunt—but the athletes played for real.

Schnall later moved to California to be in the movies, and organized another women’s baseball club there.
