Dave Pelz, Scientist Turned Golf Instructor, Is Dead at 85

Dave Pelz, who left his job as a scientist at NASA to study the short game of golf, a detour that would make him a celebrated guru of putts and wedge shots, died on March 23 at his home in Dripping Springs, Texas, near Austin. He was 85.

David Pelly, Pelz’s stepson and the chief executive of his company, Dave Pelz Golf, said the cause was prostate cancer.

While most golfers focus more on how to drive long distances, Pelz concentrated on the short game — shots from within 100 yards, including putting and chipping and blasting out of bunkers with a wedge. In his early statistical research, he found that 80 percent of shots lost to par occur within that distance, and that putting makes up 43 percent of the game.

“Golfers think that their first two shots are the game,” he said on the PBS talk show “Charlie Rose” in 2010. “They drive almost every hole. They hit to the green almost every hole. But what they don’t think about is that after you hit those first two shots, and you don’t hit the green, there are two, three or four more shots.”

Pelz, recognizable in his trademark broad-brimmed sun hat, became a major influence on the short game. He developed training aids and created clubs (he had about 20 patents); wrote instruction books; had his own Golf Channel show; opened schools for amateurs at golf resorts; and coached professional golfers.
