"Burt" was one of the first American photography writers to understand the significance of the 35mm SLR camera in the 1950's, and consequently the importance of the original Pentax camera. He was frequently awarded honors by the Japanese photography industry for his foresight and influence that helped create the consumer camera market we know today. He wrote several books about Pentax SLR film cameras which I consider to be invaluable resources, as well as other books on cameras that convey his boy-like excitement for the technology and engineering that goes into producing cameras. He had a special talent for knowing when something worked solidly or when something could be improved. He was also incredibly gifted at understanding the marketing conditions involved in manufacturing cameras and selling them. His relationship with Pentax was always kind and generous, as if he were one of their family.
Speaking personally, he was one of the most interesting and affable people I have ever had the pleasure to meet. I've had the experience to talk candidly with him one to one, and I will never forget it. Burt shared insight into the dynamics of the industry that I never would have guessed at before.
You can find warm tributes to Burt written by Jason Schneider at both T.O.P. and at PopPhoto, and by another Mason Resnick of Adorama. If you find any others, please let me know in the comments. My condolences to his colleagues and family.
