Mathematician known for creating the present day theory of algebraic geometry. His generalization from the traditional Riemann-Roch theorem released the analysis of algebraic and topological K-theory. He examined mathematics on the School of Montpellier, but performed better when he examined separately. He ceased his function in mathematics in 1970 to spotlight politics activism for eighteen years before getting stateless and relocating towards the Pyrenees. His parents had been anarchists who fled from Germany to France during Globe Battle II. His dad passed away in the Auschwitz focus camp. He was honored the Areas Medal in Mathematics in 1966, the same calendar year as Paul Cohen.
