American physicist (1912–1981)
Robert Curtis Retherford (1912–1981) was an American physicist. He was a graduate student of Willis Lamb at Columbia Radiation Laboratory. Retherford and Lamb performed the famous experiment (now known as the Lamb–Retherford experiment) revealing Lamb shift in the fine structure of hydrogen, a decisive experimental step toward a new understanding of quantum electrodynamics.[1][2]
