Robert Clark Jones

R. Clark Jones (June 30, 1916 – April 26, 2004) was an American physicist working in the field of optics. He studied at Harvard University and received his PhD in 1941. He worked at Bell Labs until 1944, and later with the Polaroid Corporation until 1982. In a sequence of publications between 1941 and 1956, he demonstrated a mathematical model to describe the polarization of coherent light, the Jones calculus.

When William Shurcliff wrote Polarized Light: Production and Use he praised R. C. Jones in the preface: "The author’s debt to Dr. R. Clark Jones, the inventor of the Jones calculus, is immeasurable. The sections dealing with the Stokes vector, the Mueller calculus, and the Jones calculus could not have been written without long and painstaking coaching by him."
