The models shown here are recreations of a Classical Mathematical Model Collection originally made by hand in plaster in the 1800′s. This portion of the collection was originally modelled by Carl Rodenberg under the direction of the famous mathematician Felix Klein.Currently portions of the collection are on display at the University of Goettingen Department of Mathematics, The University of Hong Kong Department of Mathematics, The Institute Poincare in Paris and at the Museum of Mathematics in Manhattan.The models are currently presented as fully solid, half size 1:2 recreations. Please contact us for requests for full size 1:1 models and we can also entertain requests for full size shelled models (less material and less cost).
