Trophy won by rower Jack Humphreys

This trophy was presented to Jack I Humphreys, stroke for Mosman Rowing Club. He rowed with the winning Seniors Eight crew in 1933 and runner up Champion Eight crew in 1937. Jack I Humphreys was a member of two rowing clubs. Mosman Rowing Club, located in Mosman Bay on Sydney's lower North Shore near Humphreys' Lane Cove home, and the Burns Philp Sports Club, an organisation formed and funded by Burns Philp, a wealthy and successful shipping company that employed Humphrey's as an accountant.

Mosman Rowing Club was extremely strong in the 1920s and 1930s, winning 11 straight Senior Premierships. Humphreys was the stroke of the Senior Eight who won the 1936–37 Premiership, the last the club would win for almost 20 years. He was an active member of the club donating several trophies before his death.

When rowing resumed in Australia at the end of World War I, club competition entered a new era of cooperation and national pride regardless of class and gender. Previously amateur oarsmen had been composed almost solely from the middle and upper classes, and oarswomen had not been encouraged to form clubs at all. With people now liberated from the pre-war social structures, the 1920s and 1930s saw a boom in team sports, with the formation of amateur sports associations, the successful staging of national sporting events and increased coverage of both men's and women's sport in the national press.
