The author, Jerry Syfert is a retired engineer who spent his career working on large mainframe computer systems. To relieve the pressure of his "Day Job", he became interested in woodworking. He decided to attend the Arts & Craft shows in the Baltimore/Wash DC area. He attended only the better, top grade shows. The shows proved to be quite successful as he developed his unique line of puzzles as shown in BOOK 1. His puzzles are in collections throughout the world. He wrote two books to pass onto others the skills he developed through trial and error in over 25 years. He is now residing in Sebring, Florida.
