Mr. Fried wrote 14 books, many pamphlets and hundreds of articles on horology, the science of timepieces. He taught and lectured on horology, was an industry consultant and illustrated his own books. He was a consultant for Random House Dictionary and the Merriam Webster Dictionary. He was president of the New York City Horological Society and the New York State Watchmakers Association. He was also vice president of the old Horological Institute of America and was the first American to receive the Silver Medal of the British Horological Institute. For decades, he was the watchmaker whom others consulted on the really challenging cases, a fact he attributed in part to his "tweezer skills." While he received just about every honor imaginable in his field, the one he got last fall meant more than most: A clock tower at the new world headquarters of the American Watchmakers-Clockmakers Institute near Cincinnati was dedicated in his honor.
