William Robertson Ogg, Jr. (May 10, 1888 – December 25, 1959) was a Scottish-American professional golfer, club maker, and golf course architect.

He was the first golf club maker to build and patent the forerunner to the modern perimeter-weighted or cavity back iron.

Ogg was instrumental in arranging for the first Ryder Cup matches to be held at his home course of Worcester Country Club in 1927.

[3] He laid out the Green Hill Golf Club in Worcester, Massachusetts, and the course opened up for play on April 1, 1929.

[5] After leaving Worcester, he accepted a position as professional and course superintendent at Albany Country Club in Voorheesville, New York, where in 1954 he made changes to improve the quality of the golf course by planting thousands of trees and installing a modern watering system.

He was at the peak of his playing powers in 1923 and in a first round match was in fine form when he beat Fred Baroni 2 and 1.

In June 1919, Ogg partnered with Edgar in a best ball match and beat 17-year-old Jones who on that occasion was paired with Adair.

He was the first golf club maker to build and patent the forerunner to the modern perimeter-weighted or cavity back iron.

[1] His lectures on golf fundamentals at the PGA Assistants' School in Clearwater, Florida, were described by Herb Graffis in 1960 as "classics".
