Martinus J. G. Veltman

Born 27 June 1931 in the Netherlands, Martinus Justinus Godefriedus Veltman became a theoretical physicist working on the structural problems of particle theory. He took on Gerardus 't Hooft as a doctoral student, and together they developed methods that allowed physicists to perform consistent calculations in quantum field theory — work that had eluded the field for decades. The collaboration proved definitive enough that both men shared the Nobel Prize in Physics in 1999, an unusual honor for advisor and advisee. Veltman died on 4 January 2021.
