Jerry Reinsdorf begins his 43rd season as chairman of the Chicago White Sox in 2023, only the seventh individual in Major League Baseball history to surpass the 40-year milestone as a club owner. During his time as chairman, Reinsdorf’s two professional sports teams – the White Sox and the NBA’s Chicago Bulls – have delivered seven World Championship titles to the city of Chicago and its fans, including the World Series title in 2005. Reinsdorf and the White Sox have received multiple prestigious honors in recognition of the franchise’s ongoing commitment to giving back to the community. Both of Reinsdorf’s sports franchises have donated millions of dollars to causes in the Chicago community. In 2017, owners for five Chicago sports teams – the Bears, Blackhawks, Bulls, Cubs and White Sox – joined together as the Chicago Sports Alliance to donate $1 million annually to support solutions to violence in Chicago. Reinsdorf was instrumental in MLB’s formation of the Diverse Business Partners Program, and MLB honored the White Sox with the Club Appreciation Award in 2018 to celebrate the program’s 20th anniversary. Born in Brooklyn, N.Y. on February 25, 1936, Reinsdorf graduated from George Washington University and earned a law degree from Northwestern University after moving to Chicago in 1957.
