He won professional tournaments on the highest level in Africa, Australia, Asia, North America and Europe.

From 1953 to 1965, Henning traveled the world playing on international circuits, winning the national championships of Switzerland.

A win with Gary Player at the 1965 Canada Cup convinced him to play on the PGA Tour.

Henning won the title in dramatic fashion, going out on the last hole of the tournament in the last group with Nick Price, both of them on seven under par.

During his 18 seasons on this Tour, he won three official events and two Liberty Mutual Legends of Golf Championships.
