He was an unsung hero of archery for sure...
Cant remember where I got this but reposting a short bio someone provided. This was 7 or 8 years ago if not mistaken when written:
Owen Jeffery worked for Hoyt Archery from 1942 - 1956 in building and designing bows that has won National & World titles. He was the head of the Shakespeare Archery Division for 7 years, President of manufacturing for 12 years for Fred Bear, and was Fred's hunting and fishing buddy. He designed the well known Fred Bear takedown, Super Kodiak and the Kodiak Magnum. Mr. Jeffery started his own bow building business (Jeffery's Archery in Columbia, S.C) in 1976. He has built over 50,000 bows. Owen is an accomplished archer as well, having won the Missouri State Champion six times and was Midwestern Champion, National Broadhead Champion, and Southern Regional Champion. He also taught Olympic shooters for the U.S., Russians, Japanese, French and Austrians. Jeffery is an avid bowhunter too; he took a world record whitetail buck that hung in the Fred Bear Museum. Although 84 years old, Owen Jeffery took 35 hogs last year with his bow!"
