Ronald Remsberg builds complicated structures from simple materials. In fact, Mr. Remsberg has built several scale models from nothing but matchsticks. A former Convair aeronautical engineer and builder of free-flight model aircraft, Ron used thousands of these sticks and Elmer’s glue to assemble models of some of the world’s most famous landmarks and structures. Ron has built about a dozen such models since starting in 1998. Though he has slowed down a little, the structures remain very square and precise. Ron noted that building the projects is a great tension reliever. Mr. Remsberg’s matchstick model of the Notre Dame Cathedral is 33-1/2″-long, 13-3/8″-wide, and 24″-tall.
