The silicone portrait sculpture of Ben Franklin by Robert A. Erb, Ph.D.—with apologies to Jean-Antoine Houdon—is unique in that it uses both multilayer intrinsic coloration and actual skin texture replicated from donors. Bob has been involved with research, development, and application of realistic silicone prostheses for 39 years, first at Franklin Research Center, then at SiliClone Studio. He presently offers customized intensive 2- to 5-day training courses on realistic silicone technology for 1 or 2 persons at Valley Forge—Applied Silicone Knowledge (ASK).
