Dutch physicist (1853–1928) who shared the 1902 Nobel Prize in Physics and derived the transformation equations subsequently used by Albert Einstein to describe space and time. Rare ALS in German, signed “H. A. Lorentz,” one page on a 5.5 x 3.5 postcard, June 26, 1907. Untranslated brief letter of thanks. Also addressed on the reverse in Lorentz’s hand to fellow physicist Paul Hertz. In fine condition. Lorentz was five years removed from winning the Nobel Prize in Physics at this time, and was in the process of publishing papers on what he called ‘Einstein's principle of relativity.’ He would also go on to win the Rumford Medal in 1908. The recipient of this letter, Paul Hertz, was also one of Einstein’s associates, presenting an interesting association between these extremely important scientists. RR Auction COA.
