History
Wintershall Dea's roots go back more than 125 years. The predecessor companies Wintershall and DEA Deutsche Erdoel AG were among the pioneers of the gas and oil industry in Germany, repeatedly setting trends with their technical knowledge and expertise while consistently developing their portfolios. From the second half of the 20th century, they also became increasingly involved internationally and secured ambitious licences worldwide. Since the merger in 2019, they have continued on this path together. The mining entrepreneurs Carl Julius Winter and Heinrich Grimberg founded the company Wintershall, whose initial business focused on mining potash salt; the name derives from the Germanic word "Hall", meaning salt, appended to the surname of the founder Winter. The legal predecessor of DEA was established as Deutsche Tiefbohr AG (DTA) as a drilling contractor; under managing director Rudolf Nöllenburg, DTA soon drilled its own wells, including one that struck oil. Crude oil became the main business in 1906, and DTA was renamed Deutsche Erdöl-Aktiengesellschaft (DEA) in 1911. Kali-Industrie AG, renamed Wintershall AG in 1929, was led by August Rosterg, who undertook the strategic expansion of Wintershall AG's operating activity to include crude oil.
