Jack William Nicklaus, nicknamed "the Golden Bear", is a retired American professional golfer and golf course designer. He is widely considered to be either the greatest or one of the greatest golfers of all time. He won 117 professional tournaments in his career. Over a quarter-century, he won a record 18 major championships, three more than second-placed Tiger Woods. Nicklaus focused on the major championships—the Masters Tournament, U.S. Open, Open Championship and PGA Championship—and played a selective schedule of regular PGA Tour events. He competed in 164 major tournaments, more than any other player, and finished with 73 PGA Tour victories, third behind Sam Snead (82) and Woods (82).

The United States Amateur Championship, commonly known as the U.S. Amateur, is the leading annual golf tournament in the United States for amateur golfers. It is organized by the United States Golf Association and is currently held each August over a 7-day period.
