John Acorn has been a "critter fanatic" his entire life. He is perhaps best known as the writer and host of the television series Acorn, the Nature Nut. These days John lectures at the University of Alberta and is a spokesperson for the Royal Tyrrell Museum. He still finds time for entomology and is an Associate of the E.H. Strickland Entomology Museum. John has written 15 books; including may well-received field guides and is the recipient of numerous awards. A passionate natural scientist with two science degrees under his belt, Ian Sheldon became distracted by the fine arts.

He is now an established artist, and his shows in San Francisco, New York, across Canada and in England have firmly established his presence in the art world. Ian Sheldon has been listed in the Canadian Who's Who since 2004, and further recognition has come from his other alma mater, the University of Alberta. Combining his talents as an artist with his academic knowledge of wildlife, Ian has published dozens of nature guides that grace bookshelves across North America. Hundreds of the original entomological illustrations are now a permanent part of the university's highly reputed Bruce Peel Special Collections Library, serving as a testament to the artist's skill in yet another creative arena.
