Track record and company history

Track record and 
company history

Founded in 1952, the Deutsche Seereederei was the national shipping company of the former GDR until 1990 as well as one of the largest shipping companies in the world. 

In the period from 1990 to 1993, the privatization of the company as a fiduciary subsidiary was initiated and was transferred to Horst Rahe and Nikolaus Schües in June 1993. 

Between 1993 and 1997, the company was transformed from a highly deficient shipping company into a maritime tourism and real estate company. The privatization process was successfully completed in 1997 in accordance with the contract. 

From 1997 to 2017, the company was transformed into a successful hospitality company by the Rahe shareholder group.

In 2021, DSR Hotel Holding and DER Touristik Group founded a joint venture: DR Hospitality GmbH & Co. KG, in which both companies hold a 50% stake. The newly founded company will take over the operation and marketing for the hotels and resorts of the brands A-ROSA, aja, Henri Hotels, Louis C. Jacob and Hotel Neptun and drives the growth of the group. Together, the joint venture focuses on the growth markets of the Baltic and North Seas as well as the Alpine region and Italy, as a first step.

In the same year, DSR Immobilien Development and IMPLENIA merge in a 50%-50% joint venture to form Rubus Development GmbH. The aim is to implement a clear Green Hospitality philosophy for the hotel products of Deutsche Seereederei and to pursue an innovative industrial approach in the areas of planning and realization.

By retaining its maritime name, Deutsche Seereederei acknowledges its eventful history and makes it clear that successful innovations are always based on commitment to one’s own roots.
