Billow was introduced to golf as a caddy at Racine Country Club in the late 1920s. He obviously learned a lot about the game. Billow would go on to become one of the greatest amateur golfers in history. The legendary Byron Nelson once called Billow the best long iron player, amateur or pro, in the world. Billow, who played a prominent role in helping Park High School win the 1931 State Championship, won an unprecedented seven New York State Golf Association Men's Amateur Championships. His glittering resume also consists of three runner-up finishes in the United States Men's Amateur Championship and two selections to the prestigious United States Walker Cup team, representing his country in matches at St. Andrews in 1938 and Winged Foot in 1949.
