Aaron attended the University of Florida where he was a member of the Kappa Alpha Order Fraternity (Beta Zeta Chapter).

In 2000, he made the cut at the Masters at the age of 63, breaking a record previously held by Gary Player.

Aaron played for the U.S. team in the Ryder Cup in 1969 and 1973, and had a record of one win, one tie and four losses.

Aaron is also known for being the playing partner of Argentinian Roberto De Vicenzo for the final round of the 1968 Masters Tournament.

Because De Vicenzo signed the scorecard without correcting the error, PGA rules required him to stand by the incorrect, higher score.
