The 1904 World's Fair in St. Louis, USA, awarded a gold medal to a lime wood anatomical model. This six-fold magnification of the human skull, which can be dismantled into individual sections, was one of two identical models created by the wood carver Albert Bechtel for the Munich anatomist Johannes Rückert (1854–1923). It can be viewed today in the foyer of the Anatomical Institute of the Berlin Charité.
