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.
Throughout the years he has been active in the affairs of baseball, serving on the Executive Council and Ownership, Long Range Planning, Restructuring, Expansion, Equal Opportunity, Strategic Planning, Legislative and Labor Policy Committees of Major League Baseball, he also serves on the Boards of MLB Advanced Media and MLB Enterprises. He was also the chairman of the Chicago Bulls as the team won six World Championships in the '90s (1991, 1992, 1993, 1996, 1997 and 1998).
Recently, his Chicago White Sox won the 2005 World Series, in the process Reinsdorf has collected his seventh championship ring (the first six ('91-93 & '96-98) were courtesy of Michael Jordan and the Chicago Bulls). That makes him only the third owner in the history of North American sports to win a championship in two different sports.
Some fans and columnists have accused Reinsdorf of breaking up the championship Bulls team after their third straight title and sixth in eight years claiming the Bulls could have won eight straight titles with Michael Jordan, Scottie Pippen and good support from the rest of the team that in the eight-year span included, Dennis Rodman, Horace Grant, Toni Kukoc, Ron Harper, BJ Armstrong and many other quality players.
Reinsdorf was inducted into the Appleton, Wisconsin Baseball Hall of Fame on August 5, 2006 in a ceremony at Fox Cities Stadium prior to that evening's game between the Midwest League Wisconsin Timber Rattlers and Beloit Snappers. He is being so recognized because a former Minor League club, the Appleton Foxes, were a Chicago White Sox affiliate in the early years of Reinsdorf's ownership.
