Siebel

It originated in the Klemm-Flugzeugwerke Halle that had been founded in 1934 as a branch of Leichtflugzeugbau Klemm in Böblingen. Its name changed to Siebel Flugzeugwerke when it was taken over by Friedrich Siebel in December 1937.Interessengemeinschaft Luftfahrtgeschichte im Luftsportverband Sachsen-Anhalt (Hrsg.): Dokumentation der 90-jährigen Geschichte der Luftfahrt und des Luftsports in der Region Halle (Saale), 1997

After World War II the company was revived as Siebel Flugzeugwerke ATG (SIAT) in West Germany in 1948, with its headquarters in Munich. In 1956, its headquarters were moved to Donauwörth and the company became WMD-Siebelwerke ATG (WMD/SIAT) in 1958 in cooperation with Waggon- und Maschinenbau GmbH Donauwörth (WMD). In 1968 the company was absorbed by Messerschmitt-Bölkow-Blohm after MBB became the major shareholder.[http://www.augsburger-allgemeine.de/noerdlingen/In-100-Jahren-vom-Trasswerk-zur-Firma-Eurocopter-id4618061.html Augsburger Allgemeine – In 100 Jahren vom Trasswerk zur Firma Eurocopter]
