I grew up with tropical fish and the name Dr. Herbert Axelrod was always mentioned. I read his books and magazines in the past but never really research who was the guy. Here is a link to a very interesting story in Sports Illustrated about one of the most important person linked to fish keeping in the USA. I hope you find it enlightening.
