February 28, 1971: Only five golfers have won all four of golf's modern Majors at any time during their careers, but only Jack Nicklaus, and Tiger Woods have done it multiple times. On this day, Nicklaus became the first golfer in history to do it twice.

Nicklaus completed a two-shot win at the 1971 PGA Championship in February in Palm Beach, Florida, over reigning Masters champion Billy Casper. In this championship, Nicklaus was the only player to break 70 consecutively in the first two rounds under windy conditions and finished at seven-under par 281.

By the end of 1971, Nicklaus had won four additional PGA tournaments/ With $244,490 in official PGA Tour earnings, Nicklaus established a new single season money record.

Nicklaus would win 9 more majors over the span of his career and currently holds the all-time record with 18. Woods is the next closest with 14.
