Carl Tiedemann’s separate business began on 11 May 1879 in towage, stevedoring and port shipments, buying its first tug in 1895. Stauerei und Bugsiererei Carl Tiedemnn was formed in 1900, with nephew John Rehr becoming partner in 1909. After wartime ruin and Tiedemann’s death in 1919, Rehr, his wife Emmy and her brother Carl Schramm rebuilt it. Following another wartime disruption, the concern developed primarily as stevedores, later expanding into container repair. Hans Vorberg and Michael Hanauer, Rehr’s grandson, succeeded the earlier generation. Hamburger Hafen- und Lagerhaus acquired 40% in 1988 and sold out in 1999, when Carol Zehle took 67.1%.
