William Earl "Billy" Casper, Jr. (born June 24, 1931) is an American professional golfer who was one of the most prolific tournament winners on the PGA Tour from the mid 1950s to the mid 1970s.
Casper was born in San Diego, California. He turned professional in 1954.
Between 1964 and 1970, Casper won 27 tournaments on the PGA Tour, which was more than legends Jack Nicklaus, Arnold Palmer, and Gary Player did during that time period. His victories helped him finish third in McCormack's World Golf Rankings in 1968, 1969 and 1970, the first three years they were published. He won 51 times in his career, placing him seventh on the all time list. He captained the U.S. Ryder Cup team in 1979 and was considered the best putter of his era by many. After his professional career he has been a designer for many golf courses such as The Highlands, The Palm and Eagle Crest in Sun City Summerlin, Nevada.
