The late Tom Huff had 26 WORLD'S FIRST captive breedings under his belt. He pioneered Boid breeding and coined the word Herpetoculture. He produced hundreds of rare insular Boas, not the least of which were over 600 Jamaican boas, where all existing bloodlines started. Overall he bred dozens and dozens of species, and taught a lot of us herpers, and the general public about herps, their care, and conservation.
Yup, he may not have been the most profitable, but was a great guy, and his animals were amazing. Quality, not quantity. I think back then it was more about the challenge and conservation than the all mighty buck.
He is missed.
