Jack Nicklaus, age 26, earned his third Green Jacket in an 18-hole Monday playoff and became the first back-to-back champion at the Masters.

A close friend of Nicklaus was among four that died in a private plane crash in Tennessee on Wednesday,[6] while en route to Augusta from Columbus, Ohio.

Brewer rebounded and won the tournament the next year, while Nicklaus' attempt at three consecutive titles ended early with a rare missed cut.

CBS commentator Jack Whitaker referred to the gallery at the end of the 18-hole Monday playoff as a "mob" and was banned from the next five Masters (1967–1971).
