German inventor and mechanical engineer (1858–1913) famous for the invention of the diesel engine. ALS in German, signed “Diesel,” one page, 5.25 x 3.5, September 4, 1885. Letter to Theodor Ackermann in Munich. In full (translated): “I am requesting information on the titles and years of publication of the best and most complete works about the fabrication of spirit and compressed yeast, as well as on the construction of mills; also indication of the ceiling prices of these works.—I also ask in particular for these informations on the work of Schlegel, Complete Art of the Construction of Mills.” In fine condition, with light show-through from postmark ink to the right side. At this time, Diesel was working for his former professor Carl von Linde in developing early innovations in refrigeration. Breweries were one of their firm’s largest customers, which is presumably why Diesel was conducting research on brewery processes.
