Kempinski. For 20 years the modern, progressive five-star hotel enjoyed the undisputed status of the sole luxury hotel in Berlin. In 1953 Dr Friedrich Unger sold his shares and the name Kempinski to the "Hotelbetriebs-Aktiengesellschaft", which already ran hotels such as the Baltic, the Bristol and the Kaiserhof. The name Bristol was adopted and is still used at the Kempinski Hotel at 27 Kurfürstendamm. In subsequent years, the "Hotelbetriebs-Aktiengesellschaft" took over the management of several famous hotels. In 1957 it acquired the luxurious Hotel Atlantic in Hamburg. In 1970 the General Assembly of the "Hotelbetriebs-Aktiengesellschaft" voted to change its name to "Kempinski Hotelbetriebs-Aktiengesellschaft". In the same year, a long-lasting partnership was established with Lufthansa in the form of a 50-per cent participation in the Hotel Vier Jahreszeiten in Munich, in which Lufthansa already had a holding. In 1977 the hotel company received its present name as "Kempinski Aktiengesellschaft (AG)". At the same time, the Kempinski Hotel Frankfurt Gravenbruch was added to the group's portfolio as its fourth German hotel. In 1985, Lufthansa acquired shares in Kempinski AG and thereby enabled the hotel company to operate Kempinski hotels abroad too. A year later, Kempinski AG, Lufthansa and the finance company Rolaco S.A. founded Kempinski Hotels S.A., with its head office in Geneva. In 1993 Kempinski AG acquired all the shares in Kempinski S.A. The Bangkok-based Dusit Sindhorn Company Ltd took over Kempinski in November 1994, when it acquired a 52% stake. The 50:50 joint venture between Dusit Thani Group, and the Siam Commercial Bank eventually accumulated an 83% stake in the group, and Dusit Thani exited from the joint venture in 1998 when it sold out to its partner. In February 2017, the two existing shareholders of Kempinski AG formalized previous plans for an equity transfer between them. The majority shares of Kempinski AG are held by the existing Bahraini shareholder while the shareholder from Thailand holds a minority. In the same month, Kempinski announced the opening of its first luxury hotel in Cuba.
