Ferdinand Adolph Lange founded A. Lange & Söhne in 1845 in Glashutte. He had one goal, resolved unemployment. With financial help from the state, he hires 15 young persons to be trained as watchmakers. Many times, the company was on the verge of bankruptcy but in 1875 hard work pays as the sons and grandsons of Adolph Lange inherited a flourishing business with over 100 employees producing pocket watches. During the second world war, the Lufwaffe ordered pilots’ wristwatches. Civilian watches were also produced. In 1989 at the end of the Berlin wall, Walter Lange, the founder’s great-grand-son saw the opportunity to revive the family business. With VDO/Mannesmann Group, which in 1991 took a stake in Lange Uhren GMBH, he set-up an ultra modern production facility in Glashutte to manufacture precision watch-movements bearing the « Made in Germany ». Amid the first watches were the « Lange 1 » then the « Pour le Merite » a tourbillon with fusee and chain. In 1997, came the « Sax-O-Matik » with the self winding L921 movement. In 1999, the famous caliber L951.1 came in the « Datograph ». Since July 2000, Lange is owned by Richemont Group. The last most famous models are the « Lange 1 Zeitzone », the « Tourbograph » and the smart 3-handed « Richard Lange » manually wound watch.
