Jerry Michael Reinsdorf (born February 25, 1936) is the owner of the NBA's Chicago Bulls and MLB's Chicago White Sox. He started his professional life as a tax attorney with the Internal Revenue Service. He has been the owner of the White Sox and Bulls for over 35 years. As of November 2021, his net worth was estimated at US$1.7 billion. He made his initial fortune in real estate, taking advantage of the Frank Lyon Co. v. United States decision by the United States Supreme Court which allowed economic owners of realty to sell property and lease it back, while transferring the tax deduction for depreciation to the title owner. As the owner and chairman of the Chicago Bulls since 1985, he oversaw the franchise turning into a lucrative business that won six NBA Championships in the 1990s (1991–1993 and 1996–1998). He is controversial for his involvement (along with Jerry Krause) in breaking up the championship team by not hiring back Phil Jackson. He signed Michael Jordan as a baseball player during his sabbatical from basketball. He also moved the Bulls from Chicago Stadium to the United Center. Since purchasing the White Sox in 1981, the franchise made the playoffs in 1983 for the first time since 1959, and won the World Series in 2005 for the first time since 1917, and is the only time during tenure as owner that the White Sox have won a playoff series. Reinsdorf moved the White Sox from Comiskey Park to New Comiskey Park in 1991 (now known as Guaranteed Rate Field). In both sporting endeavors, he has developed a reputation as an anti-labor union hardliner. Since the early 1990s, he has been considered one of the most, if not the most, influential basketball owners. He has been influential in instituting the salary cap and revenue sharing. On April 4, 2016, Reinsdorf was elected to the Naismith Memorial Basketball Hall of Fame as a contributor. From Wikipedia
