Brian Thomas (“Bud” or “Buddy”) Allin (October 13, 1944 – March 10, 2007) was an American professional golfer who won five PGA Tour events in the 1970s. Allin was born in Bremerton, Washington. He learned to play golf at age 13 while working as a caddy at the Santa Barbara Municipal Golf Course in Santa Barbara, California. A prodigal player, Allin attended Brigham Young University in Provo, Utah and was a member on the golf team along with Johnny Miller. He served in the Army as an artillery officer during the Vietnam War earning four decorations including the Bronze Star and an Air medal. He turned pro in 1969 and qualified for the PGA Tour on his first attempt citing the fact that golf was no “big deal” compared to war. Buddy Allin’s first win on the PGA Tour came in 1971 at the Greater Greensboro Open when he defeated Dave Eichelberger and Rod Funseth on the first extra-hole in a playoff. He would win five times in five years between 1971 and 1976. His best season was in 1974 when he won the Doral Ryder Open and the Byron Nelson Classic, which propelled him to a ninth place finish on the money list. His best finish in a major was a T-10 at the 1974 U.S. Open and the 1975 PGA Championship. He had 3 dozen top-10 finishes in PGA Tour events in his career; his last win came at the 1976 Pleasant Valley Classic. Buddy Allin was well respected by his fellow tour players for his personality and his acute game but elected to leave the tour due to health issues in the early 1980s.

After reaching the age of 50 in October 1994, Buddy Allin began competing on the Senior PGA Tour. He was nominated for Rookie of the Year in 1995, after an outstanding first full season. He also shot a Senior Tour record low round of 61 at the FHP Healthcare Classic that year. His lone Senior tour win came in 1997 at the American Express Invitational where he 2-putted from 60 feet on the 72nd hole to win by one stroke over Jim Colbert. He competed five full seasons before electing to leave the tour despite being exempt for the 2000 season. Allin devoted the last years of his life to teaching at the San Diego Golf Academy and authoring his instructional manual, Center-Line, as well as an instructional DVD, Preferences. He lived in Boulder City, Nevada as well as California. He died in Hemet, California at the age of 62 from multiple forms of cancer.
