Bill Koch (businessman)

In September 2021 Koch was inducted into the Sons of the American Revolution under Patriot William Burnett (b. 1730 d. 1791) who served as Surgeon General, Chief Physician of the Army's Eastern Department and of the hospital in New Jersey as well as a New Jersey Delegate to the First Continental Congress.

Koch is a collector of art and wine. He has filed several high-profile suits against sellers of counterfeit wines, most notably a suit against Hardy Rodenstock for the sale of wine purported to have been owned by Thomas Jefferson. Koch also sued Rudy Kurniawan and the auction house Acker, Merrall & Condit, through whom Koch purchased Kurniawan's wine. Koch filed the suit against Renee Angove in 2019 and was reported to have reached a settlement for $3 million in July 2014.

Koch gave $2 million to Restore Our Future, a PAC created to support 2012 Republican Party Presidential candidate Mitt Romney.

After leaving Koch Industries, he became the founder and president of the Oxbow Group, an energy development holding company based in West Palm Beach, Florida. In 2011, Oxbow donated $750,000 to Restore Our Future, Inc., the "SuperPAC" supporting Mitt Romney's presidential campaign. Koch was also an investor in Kendall Square Research, a short-lived supercomputer company.

In June 2011, he purchased a 130-year-old photo of the legendary outlaw Billy the Kid for the amount of $2.3 million at a Denver auction.

Koch co-chairs the Alliance to Protect Nantucket Sound, a group formed to fight the Cape Wind project to build an offshore wind farm of 130 turbines. In 2005, Koch contributed $500,000 in donations to the alliance directly and more than $1 million toward lobbyist efforts to defeat the project.

Koch's collection of maritime memorabilia includes model ships, antique nautical instruments, and paintings of ships and seascapes. A 2005 show at the Museum of Fine Arts in Boston featured his collections, including the America 3 and the yacht it defeated, Il Moro di Venezia. The show was also criticized, however, for glamorizing Koch at the expense of the museum's educational function. Koch had helped finance the show, including paying the cost to move the boats from Rhode Island. He previously owned the former French Class America F1 - IACC F1 renamed later USA-2.

In 2005, Koch married Bridget Rooney (b. 1962) at a ceremony in Colorado. The couple has one daughter, Kaitlin. Bridget Rooney Koch is the granddaughter of the original owner of the Pittsburgh Steelers football franchise, Art Rooney (1901–1988). The Kochs are part-time residents of Palm Beach, Florida.

Legal disputes against Charles and David lasted some two decades. Bill and his eldest brother, Frederick, sided with J. Howard Marshall III, J. Howard Marshall II's eldest son, against Charles and David at one point, in order to take over the company. In 2001, Koch reached a settlement where he had charged the company was taking oil from federal and Indian land. This settlement ended all litigation between the brothers. CBS News reported that Koch Industries settled for $25 million, and Bill received one-third of the settlement for bringing the suit.

In 1995, Koch financed another team to compete for the cup. This time the crew consisted entirely of women except for tactician David Dellenbaugh, on a yacht named Mighty Mary. However, the boat lost to Dennis Conner's Stars & Stripes in the trials.

In 1995, he filed a lawsuit against his former lover, Catherine de Castelbajac, to evict her from his $2.5 million condominium at the Four Seasons Hotel in Boston. He said he had allowed her to move in the previous year so she could attend Simmons College, as he seldom used the apartment. When he tried to end the relationship, de Castelbajac refused to move out and claimed he had broken his promises to her. A jury ruled in Koch's favor after a trial that was noted for its disclosure of torrid letters and faxes between the two.

Koch was inducted into the America's Cup Hall of Fame in 1993. Koch was inducted into the National Sailing Hall of Fame in 2018.

Koch won the America's Cup in 1992 with the yacht America, defeating the Italian challenger Il Moro di Venezia. America 3's overall record, including trials, was 28–10. Koch reportedly spent around $65 million on his effort and though an amateur, sailed on the crew himself, assisted by veteran sailors like Buddy Melges.

In 1984, Koch married Joan Granlund, with whom he had a son, Wyatt. The marriage ended in divorce.

Koch worked in his family's company. He and his eldest brother Frederick R. Koch had inherited Koch Industries stock. In 1980, after an unsuccessful attempt to take over the company from Charles, William was fired from the company. In 1983 the stock netted them $800 million in a sale to their brothers, Charles and David.

William Ingraham Koch (/koʊk/ KOHK; born May 3, 1940) is an American billionaire businessman, sailor, and collector. His boat was the winner of the America's Cup in 1992. Forbes estimated Koch's net worth at $1.8 billion in 2019, from oil and other investments.

Koch attended Culver Military Academy in Culver, Indiana. He graduated with bachelor's, master's, and doctoral degrees in chemical engineering, all from Massachusetts Institute of Technology. David Koch (1940−2019) was his twin brother. His other brothers are Frederick R. Koch (1933−2020) and Charles Koch (born 1935).
