Joseph Sobek

Died 27 Mar 1998 at age 79 (born 5 Apr 1918).American inventor of racquetball who developed the sport (1950) to play at the Greenwich, Connecticut, YMCA. As a squash and tennis professional for seven years, he invented racquetball as an alternative indoor racquet sport. He drafted rules, drew a racquet design, which was created in 1951 by Magnan Racket Manufacturing Company. To promote his invention, he founded the Paddle Rackets Association with a group of players. He withdrew from active promotion as the sport quickly rose in popularity, as an athletic activity that was easy to learn, and needed no power or strength to enjoy. By the early 70's, there were court clubs in every state. There are now millions of players, and it is an Olympic sport.«
