Nicklaus, Jack William, 1940-, American golfer, b. Columbus, Ohio. He began playing golf at the age of 10 and before becoming a professional in late 1961 was considered by many the greatest amateur golfer since Bobby Jones. In his first year as a professional in 1962 he defeated Arnold Palmer in the U.S. Open and won the first World Series of Golf. Capable of hitting drives in excess of 300 yards (270 m), Nicklaus won the Masters six times, the U.S. Open four times, the British Open three times, and the PGA Championship five times.

Szostak, Jack William, 1952-, American molecular biologist, b. London, England, Ph.D. Cornell, 1977. Szostak has been a professor at Harvard Medical School and a researcher at Massachusetts General Hospital since 1977. He shared the 2009 Nobel Prize in Physiology or Medicine with Carol Greider and Elizabeth Blackburn for solving the problem of how chromosomes make complete copies of themselves during cell division and how they protect themselves against degradation during this process. Szostak and Blackburn discovered that a unique DNA sequence in telomeres (the region of DNA at the ends of the chromosomes) protects the chromosomes from degradation. In addition to increasing understanding of the cell, the three researchers's work shed light on disease mechanisms and stimulated the development of potential new disease therapies.
