Forty years after founding his Jones Group apparel chain, Kimmel stepped down as chairman in January 2014. His second career as a film producer via his Sidney Kimmel Entertainment shows no signs of slowing: his Matthew McConaughey caper 'The Lincoln Lawyer' is out this March, and he's in pre-production on the Amanda Seyfreid-starring thriller 'Gone'. Joined the Gates and Buffett Giving Pledge in 2010; in his accompanying letter, he wrote: "My thinking is rather simple: I learned as a young boy that sharing with others is the right thing to do". Kimmel founded women's outfitter Jones Apparel with a partner while working at W.R.Grace chemical company in 1970; became chairman five years later. Stepped down as CEO in 2002. The Philadelphia-born retailer's group started snapping up other brands in the 1980s and 90s; now owns Nine West, Gloria Vanderbilt and Evan-Picone. Owns 5% of the Miami Heat basketball team. Kimmel, whose clothing company Jones Apparel Co. was sold in 2014 for $2.2 billion, has been a movie producer for decades. He is credited with more than 55 titles since the 1980s. He is listed by Forbes as worth $1.3 billion and is a leading cancer research donor in addition to his giving to construction of the Kimmel Center for Performing Arts on South Broad Street and other cultural institutions. In 2014, he gave $110 million to Jefferson Medical College, which was renamed the Sidney Kimmel Medical College of Thomas Jefferson University. He spent a short time at Temple University before going into the garment industry. He founded Jones New York in the 1960s, and grew the company to include brands like Nine West, Anne Klein, Stuart Weitzman, Joan & David, Gloria Vanderbilt, Barneys New York and Kurt Geiger. He took the company public in 1991, and ramped up his charitable efforts. A decade later, in 2002, he stepped down as CEO, but remained chairman until 2014 when Jones was sold to Sycamore Partners, a private equity firm.
