Ludwig Darmstaedter
Ludwig Darmstaedter (9 August 1846 – 18 October 1927) was a German chemist and historian of science. From 1865 he studied chemistry under Robert Bunsen and Emil Erlenmeyer at the University of Heidelberg, then furthered his education in Leipzig as a student of Hermann Kolbe. Afterwards, he relocated to Berlin, where he performed studies on alkali fusion of sulfonic acids in the laboratory of Karl Hermann Wichelhaus. From 1872, with Benno Jaffé, he was involved with industrial chemical research; e.g. glycerin extraction. Later on in his career, he conducted investigations on the composition and synthesis of lanolin. His interest  in the historical development of chemistry inspired him to compile an extensive collection of manuscripts of scientists (""Dokumentensammlung Darmstaedter"") in the Prussian State Library at Berlin. From 1917 onwards, Darmstaedter financed Wilhelm Doegen's efforts to record speech samples of persons of public interest. Since 1952 the "Paul Ehrlich- und Ludwig Darmstaedter Preis" has been awarded in Germany for outstanding contributions in the field of medicine.
