5.14 Nestler, Germany

Another German maker of fine slide rules, Albert Nestler AG was founded in 1878 and lasted 100 years in the slide rule business. According to the Oughtred Society Albert Einstein favored the Nestler in his work, particularly the No. 23R. The same claims are made for Wernher von Braun, the famous German-American aerospace engineer.

Albert Nestler made his own dividing engine that he used to place scales on stocks, first those purchased from Dennert & Pape, and later stock that Nestler manufactured themselves. Prior to World War II, Nestler was shipping slide rules around the world, including to the USA. (For example, see Kolesch and Company, USA.) Their slide rule production ended in 1978.
