Peter Debye

Died 2 Nov 1966 at age 82 (born 24 Mar 1884). Peter Joseph Wilhelm Debye was a Dutch-American physical chemist whose investigations of dipole moments, X rays, and light scattering in gases brought him the 1936 Nobel Prize for Chemistry. Most of his work was in chemical-physics with special interest in electrolytes and dipolar momentum analysis. He established a theory of specific heat with some improvements on that proposed by Einstein. Debye performed important work in the analysis of crystalline powders using X-ray diffraction techniques. He also determined the dimensions of gaseous molecules and the interatomic distances using X-rays.
