Kramer also created the Men's Grand Prix points system. In 1972, he helped found the Association of Tennis Professionals.

He was particularly known for his powerful serve and forehand, as well as his ability to play "percentage tennis." This strategy maximized his efforts on certain points and in certain games during the course of a match to increase his chances of winning. The key was to hold serve at all costs, which was one of many things that made Kramer one of the greatest players of all time.

Born Aug. 1, 1921, in Las Vegas, Kramer enlisted in the Coast Guard during World War II in 1943 and was attached to a commissary supply depot in Long Beach, California. 

In early 1944, he transferred to New London, Connecticut, for Officer Candidate School at the Coast Guard Academy.

During his Coast Guard duties, Kramer played tennis matches to raise money for war bonds. A match against Army Air Force tennis player Don Budge raised $2.5 million in war bonds.

In late March 1944, Kramer was commissioned a Coast Guard ensign. He was assigned to Alameda, California, and then to Brisbane, Australia, in January 1945. In the summer of 1945, he embarked on a cutter in the Pacific. He was honorably discharged from the Coast Guard as a lieutenant in January 1946.

Kramer wrote his autobiography "The Game: My 40 Years in Tennis" in 1979. In it, he calls Helen Wills Moody the best women's tennis player that he'd ever seen.

Kramer died from cancer on Sept. 12, 2009, at his home in the Bel Air neighborhood of Los Angeles. He was 88.

In the 2012 Tennis Channel series "100 Greatest of All Time," Kramer was ranked the 21st greatest male tennis player of all time.
