When was HOCHTIEF founded?

HOCHTIEF was founded under the name of "Gebrüder Helfmann, Bauunternehmer" in 1873 by the brothers Philipp and Balthasar Helfmann in Bornheim near Frankfurt am Main. On April 1, 1884, the construction company was entered into the trade register of Frankfurt am Main as a general partnership (OHG). After the death of Balthasar, Philipp Helfmann wanted to turn the company into a stock corporation. Formally, the stock corporation "Aktiengesellschaft für Hoch- und Tiefbauten" founded by Philipp Helfmann in 1896 acquired the company "Gebrüder Helfmann, Bauunternehmer". In 1924, the company was renamed "HOCHTIEF Aktiengesellschaft für Hoch- und Tiefbauten vorm. Gebr. Helfmann". You can find further information on HOCHTIEF's chronicle here.
