Jackson Donald Fleck (November 8, 1921 – March 21, 2014) was an American professional golfer, best known for winning the U.S. Open in 1955 in a playoff over Ben Hogan.

Fleck started as a caddie for a local dentist in the mid-1930s, turned professional in 1939,[6] and worked as an assistant golf pro at the Des Moines Country Club for five dollars a week prior to World War II.

He joined the military in 1942 and served in the U.S. Navy as a quartermaster;[7] he participated in the D-Day invasion from a British rocket-firing ship off Normandy's Utah Beach.

Fleck won an 18-hole Sunday playoff by three strokes over his idol, Ben Hogan, at the Olympic Club in San Francisco.

[20] In 1993, needing money to salvage a little golf course he owned in rural Arkansas that had been damaged by flooding, a place he called Li'l Bit of Heaven, he sold his 1955 U.S. Open gold medal.

[21] Fleck met his first wife, Lynn Burnsdale of Chicago, when she stopped in the municipal course's pro shop in Davenport in 1949 with a club that needed repair.
