I felt like doing some searching. Fred Bear died in 1988. His 10 commandments were published in 1981 in Field & Streams.
"Bear (1902–1988) was a late bloomer who took up archery when he was 29. During the Depression, he was out of a job after the factory he was operating burned down. Fred knew how to make bows. A friend from the factory had been in sales. Together they scraped up all they could, which was $1,200, and went into business, founding the company that became Bear Archery. In 1947, Fred and his wife moved the business to Grayling, Michigan, and lived in a tent by the river to save money. As late as 1961, making ends meet proved challenging. But Fred was a hunter. He didn’t give up easily."
