The first dome that could be called "geodesic" in every respect was designed after World War I byWalther Bauersfeld, chief engineer of the Carl Zeiss optical company, for a planetarium to house his planetarium projector. A first, small dome was patented, constructed by the firm of Dykerhoff and Wydmann on the roof of the Zeiss plant in Jena, Germany. A larger dome, called "The Wonder of Jena" opened to the public in July 1926. Some 20 years later, R. Buckminster Fuller named the dome "geodesic" lattice of interlocking icosahedrons that could be skinned with a protective cover. Although Fuller was not the original inventor, he is credited with the U.S. popularization of the idea for which he received U.S. patent 2,682,235  29 June 1954.
