Irwin L. Jacobs (July 15, 1941 – 10 April 2019) was an American businessman. He was the CEO of several large corporations, formerly including the now-bankrupt Genmar Holdings, boat-building company. He earned the nickname "Irv the Liquidator" for his aggressive business practices in the 1970s and early 1980s. In 1973, Jacobs founded COMB ("Close-out Merchandise Buyers"), a catalog-based mail-order retailer. In 1986, COMB and several cable television operators created the Cable Value Network (CVN), a pioneering television shopping channel which was later purchased by Joseph Segel's QVC. Jacobs, based in Minneapolis, became wealthy by taking big stakes in Fortune 500 conglomerates, usually to unlock value by breaking them up.
