Peter Hathaway Capstick (19401996) was an American hunter and author. Born in New Jersey and educated at the University of Virginia, he walked away from a successful Wall Street career shortly before his thirtieth birthday to become a professional hunter, first in Central and South America and later (and most famously) in Africa. Capstick spent much of his life in Africa, a land he called his "source of inspiration." A chain smoker and heavy drinker, he died at age 56 from complications following heart surgery.
After a short career as a Wall Street stockbroker, Capstick headed to Latin America, where he traveled widely while hunting, fishing, and mastering the Spanish language. A few years later he returned to New York, where he founded a business arranging professionally guided hunting trips. Shortly thereafter he took a position as hunting and fishing director of Winchester Adventures of New York, a subsidiary of the famous gun manufacturer. In that capacity he made his first trip to Africa in 1968. Subsequently he worked as a professional hunter and game ranger in Zambia, Botswana and Rhodesia.
Capstick started writing about his adventures in the late 1960s, and published numerous articles in various sporting magazines. In 1977 he published his first book, Death in the Long Grass, which became a commercial success and established his reputation as an author of true adventure stories. Capstick is frequently compared to Ernest Hemingway and Robert Ruark in discussions of influential African hunting authors.
In early 1996 Capstick was a keynote speaker at the annual Safari Club International convention in Reno, Nevada when he collapsed in his hotel room and was diagnosed with exhaustion. He was immediately flown back to his adopted country of South Africa and underwent heart bypass surgery in a Pretoria hospital. He died just before midnight on March 13 of complications from surgery.
After a small private ceremony, his ashes were scattered over the Chobe River in northeastern Botswana.
The .470 Capstick rifle cartridge, developed by A-Square's Colonel Arthur B. Alphin in 1990, bears his name. His legacy is saluted by The Dallas Safari Club's annual Peter Hathaway Capstick Hunting Heritage Award for the promotion of responsible hunting and wildlife conservation.
There are those who have attempted to discredit his stories and achievements. True or not, he was one hell of a writer and story teller. The fact the Dallas Safari Club presents an annual award in his name speaks volumes to those who are out to prove him a farce. What these doubters have to gain from a dead man is beyond me.
