Overview
Reederei Zürich AG was a Swiss shipping company associated with Migros and founded in Zürich in 1951. It emerged from plans connected with Gottlieb Duttweiler's interest in creating a Swiss merchant marine during the Second World War and its aftermath. Duttweiler, the founder of Migros, had withdrawn from Maritime Suisse S.A. with the Migros-Genossenschafts-Bund in 1943. Although an ambitious proposal to establish a regular Swiss liner service between the United States and the Mediterranean using Victory and Liberty ships was not realized, the initiative eventually led to the creation of Reederei Zürich AG. The company was established in late July or early August 1951 by Duttweiler, Migros-Genossenschafts-Bund, and Zürich construction entrepreneur Ernst Göhner. Its registered office was at Limmatstrasse 152 in Zürich, the same address used by Migros. The initial board reflected the relationship with Migros and its business partners: Duttweiler served as president, Göhner as vice-president, while Heinrich Rengel and Oskar Meier also held board roles. Reederei Zürich initially entered ocean shipping by ordering two fast freighters from H. C. Stülcken in Hamburg. The vessels were named Adele and Amelia, after the wives of Duttweiler and Göhner. The ships were built with engines supplied by Gebrüder Sulzer of Winterthur. Swiss government support covered a substantial share of the construction costs on the condition that the vessels could be made available to the government during a crisis. This arrangement reflected the strategic importance attached to maintaining national maritime transport capacity in a landlocked country. The two ocean-going ships were later chartered to Saguenay and operated for a period under names beginning with the prefix “Sun,” including Sunadele and Sunamelia. The naming generated criticism from some Swiss parliamentarians and newspapers, who objected to the English prefix on ships associated with Switzerland. The charter of Sunadele ended in 1966, after which the vessel resumed the name Adele before being sold. Sunamelia remained under charter until the end of 1968, returned to the name Amelia, and was sold in early 1970. Because the company anticipated significant expenditure for the ships' next classification renewal, it decided to dispose of both vessels. Reederei Zürich did not replace them, effectively ending its ocean-shipping activities. The company subsequently focused on inland shipping, particularly cargo transport on the Rhine. By 1984, its Rhine operation comprised 16 units with a combined carrying capacity of approximately 26,000 tonnes. This activity was managed through the Rheinreederei Zürich AG structure, which appears to have been established during the 1960s. The inland fleet formed part of a broader consolidation of Swiss river-shipping interests. After Migros acquired a majority interest in the financially troubled Schweizerische Reederei & Neptun AG in 1984, a joint operating organization for Reederei Zürich AG and Schweizerische Reederei & Neptun AG began on 1 March 1986. The arrangement was intended to operate the two companies' Rhine fleets together. Reederei Zürich AG was removed from the Swiss commercial register on 30 September 1996. The later sale of Schweizerische Reederei & Neptun AG in 2000 marked another stage in the dissolution and restructuring of the associated shipping businesses. The historical Reederei Zürich AG should not be confused with a later company of the same name established after the original shipping company had been deleted from the commercial registers.
History
Reederei Zürich AG developed out of Swiss efforts to establish a merchant marine during and after the Second World War. In 1943, Gottlieb Duttweiler and the Migros-Genossenschafts-Bund withdrew from Maritime Suisse S.A. Duttweiler had considered creating a Swiss shipping company operating a liner service between the United States and the Mediterranean with a fleet of Victory and Liberty ships, but that proposal was never implemented. The eventual company was founded in Zürich in 1951, with the foundation dated in contemporary accounts to either 26 July or 3 August. Its initiators were Duttweiler, Migros-Genossenschafts-Bund, and construction entrepreneur Ernst Göhner. The company's registered office was at Migros's address on Limmatstrasse in Zürich. Duttweiler became board president, Göhner vice-president, and Heinrich Rengel and Oskar Meier joined the board. Reederei Zürich entered ocean shipping with two fast freighters built by H. C. Stülcken in Hamburg. Adele was named for Adele Duttweiler, while Amelia honored Amelia Göhner. Their engines were supplied separately by Gebrüder Sulzer in Winterthur. The Swiss government financed a large portion of the construction under an arrangement requiring the vessels to be available for government use during a crisis. The ships therefore represented both a commercial investment and an element of Swiss strategic transport planning. The vessels were later chartered to Saguenay and operated as Sunadele and Sunamelia. The naming was controversial in Switzerland because some politicians and newspapers objected to the English “Sun” prefix. Sunadele returned to the name Adele in 1966 after its charter ended and was sold later that year. Sunamelia continued under charter through 1968, returned to the name Amelia, and was sold in February 1970. Anticipated costs associated with the next classification renewal contributed to the decision to sell the company's only ocean-going ships. No replacement vessels were acquired, ending Reederei Zürich's ocean operations. The company retained an inland-shipping presence on the Rhine. By 1984, the Rhine fleet consisted of 16 units with a total carrying capacity of about 26,000 tonnes. The operation was associated with Rheinreederei Zürich AG, a related structure believed to have been formed around 1964. Migros's acquisition of a majority interest in the financially troubled Schweizerische Reederei & Neptun AG in 1984 created the basis for closer operational integration. On 1 March 1986, a joint organization began operating the Rhine fleets of Reederei Zürich AG and Schweizerische Reederei & Neptun AG. Reederei Zürich AG was deleted from the commercial register on 30 September 1996. Schweizerische Reederei & Neptun AG was later sold in 2000. A company with the same name was established after the historical shipping company had been removed from the register; that later entity is distinct from the subject of this dossier.
