||1945: Mathematician Jacques Feldbau dies at the Ganacker Camp, annex of the concentration camp of Flossenbürg in Germany.

He is the one who first proved that a fiber bundle over a simplex is trivializable and who used this to classify bundles over spheres.

He discovered the Czochralski method in 1916, when he accidentally dipped his pen into a crucible of molten tin rather than his inkwell. He immediately pulled his pen out to discover that a thin thread of solidified metal was hanging from the nib. The nib was replaced by a capillary, and Czochralski verified that the crystallized metal was a single crystal. Pic.

  • 1904: American physicist and academic J. Robert Oppenheimer born. His achievements in physics will include the Born–Oppenheimer approximation for molecular wavefunctions, and the first prediction of quantum tunneling. Oppenheimer will be called the "father of the atomic bomb" for his role in the Manhattan Project.
