Jerry Reinsdorf (born February 25 1936 in Brooklyn, New York) is the owner of Chicago White Sox and the Chicago Bulls. He has been the head of the White Sox and Bulls for over 20 years. He was, for many years, an attorney, certified public accountant and real-estate developer.

Recently, he helped the White Sox win the 2005 World Series and, in the process, collected his seventh championship ring overall (the first six were all with the Bulls in the 1990s), becoming the third owner in the history of North American sports to win a championship in two different sports.

In a move that was very public and highly criticized, Reinsdorf broke up the championship Bulls team after their third straight title and sixth in eight years.
