Hendrik Antoon Lorentz autograph letter signed, dated 15 August 1921 from Haarlem, Netherlands where he taught at the University of Leiden. The Nobel Prize winning physicist writes a letter of recommendation for fellow physicist Paul Sophus Epstein, reading in part, ''Dr. Paul S. Epstein's scientific work has given me the impression that he is one of the very best of young physicists. He combines great mathematical skill with a keen understanding of physical problems and has obtained results that will undoubtedly be of lasting value. / He has especially contributed to the development of the quantum theory...Indeed, whereas the older theories of light and electricity were unable to account for the effect discovered by Stark, the splitting of spectral lines by the action of electric force, Epstein succeeded in giving a full and highly satisfactory explanation of this phenomenon...following the principles underlying Bohr's theory of spectra, he deduced not only the great number of components observed with many spectral lines, but also the absolute values of their mutual distances...I have come to appreciate very much his vast knowledge of the facts and theories of modern physics...H.A. Lorentz''. Later in 1921, Epstein was recruited to teach at Caltech, where he remained the rest of his career. Two page letter on bifolium stationery measures 8.5'' x 10.75''. Folds and a few chips to edges, else near fine condition.
