Kasimir Fajans Radioactivity Polish Jewish Chemist Hand Signed Letter

CHAU1660 A vintage 1973 fully hand written and signed letter from Polish chemist Kasimir Fajans who was a Polish American physical chemist of Polish-Jewish origin, a pioneer in the science of radioactivity and the co-discoverer of chemical element protactinium.  This is a fully hand written and signed letter by Kasimir Fajans on tracking paper in blue biro folded once where posted otherwise mint condition - I cant translate the letter but I am sure a local historian with knowledge will be able to do so.

In 1910 Fajans took a job at the laboratory of Ernest Rutherford in Manchester, where the nucleus was discovered. He then returned to Germany, where he became an assistant and subsequently assistant professor at the Technical University of Karlsruhe, researching radioactivity. In 1917 he headed the Faculty of Physical Chemistry at Munich University, and in 1932 became the Head of the Institute of Physical Chemistry established by the Rockefeller Foundation. In 1935 he left Germany due to escalating Nazi persecution. He stayed for a while in Cambridge and then moved to the University of Michigan where he worked until his demise. In 1959 he became an honorary member of the Polish Chemical Society. Fajans retired at age of seventy but never stopped working. He died May 18, 1975, in Ann Arbor, Michigan.
