Emil Ziehl (1873[1] – 1 June 1939) was aGerman engineer and entrepreneur.[1]
He grew up with five other siblings in his father's blacksmith's and cart workshop inBrandenburg, and was supposed to start an apprenticeship in the family business. Due to the drawing talent shown by the young Ziehl, his teacher convinced Ziehl's father to send him to theRackow Drawing School.
Following his professor's recommendation, he started working atAEG as an engineer. In the development of electro-motors, he pioneered in the messing and testing of generators. In 1897, he began atBerliner Maschinenbau AG, where he developed the firstrotor powered by electricity with cardanic suspension and with that the firstexternal rotor motor. The German patent was given in 1904, with the US-patent already granted on 27 November 1900.[2]
With the Swiss investor Eduard Abegg he founded in early 1910 the companyZiehl-Abegg. Ziehl had big expectations for Abegg, who was to develop wind turbines.[3] After the company's logo (with Abegg's name on it) was already made public, Abegg failed to bring the promised funds. The introduced patent for the wind motors also turned out to be unsuitable. Abegg left the company two months later.[3]
Ziehl had three daughters and two sons. The eldest son,Günther Ziehl, was born on 5 September 1913 and the youngest, Heinz, in 1917.[4] Günther Ziehl began his studies in 1935 at theTechnische Hochschule in Charlottenburg (nowTechnische Universität Berlin)] and later led his father's company.
TheSchöntal community inBaden-Württemberg acknowledged the work of Ziehl in 2015 naming a street after him. The street is located in Bieringen, a locality of Schöntal where Ziehl-Abegg has a production plant. The street sign was presented on the occasion of the 50-year celebration of production work at Schöntal-Bieringen. The mayor, Patrizia Filz, presented this sign to the grandson of Ziehl, Uwe Ziehl.[5]
