Emil Otto Hoppé (14 April 1878 – 9 December 1972) was a German-born British portrait, travel, and topographic photographer active between 1907 and 1945. Born into a wealthy family in Munich, he moved to London in 1900 originally to train as a financier, but took up photography and rapidly achieved great success.He was "the only son of a prominent banker, and was educated in the finest schools of Munich, Paris and Vienna. On leaving school he served apprenticeships in German banks for ten years, before accepting a position with the Shanghai Banking Corporation. He never arrived in China. The first leg of his journey took him to England where he met an old school friend. Hoppé married his [old school friend's] sister, Marion Bliersbach and stayed in London. While working for the Deutsche Bank, he was becoming increasingly enamoured with photography, and, in 1907, jettisoned his commercial career and opened a portrait studio. Within a few years E.O. Hoppé was the undisputed leader of pictorial portraiture in Europe. To say that someone has a "household name" has become a cliché, yet in Hoppé's case the phrase is apt. Rarely in the history of the medium has a photographer been so famous in his own lifetime among the general public. He was as famous as his sitters. It is difficult to think of a prominent name in the fields of politics, art, literature, and the theatre who did not pose for his camera."Although Hoppé was one of the most important photographic artists of his era and highly celebrated in his time, in 1954, at the age of 76, he sold his body of photographic work to a commercial London picture archive, the Mansell Collection. In the collection it was filed by subject in with millions of other stock pictures and no longer accessible by author. Most all of Hoppé's photographic work—that which gained him the reputation as Britain's most influential international photographer between 1907 and 1939—was accidentally obscured from photo-historians and from photo-history itself. It remained there for over thirty years after Hoppé's death, and was not fully accessible to the public until the collection closed down and was acquired by new owners in America.In 1994 photographic art curator Graham Howe retrieved Hoppé's photographic work from the picture library and rejoined it with the Hoppé family archive of photographs and biographical documents, reconstituting for the first time since 1954 the complete E.O. Hoppé Collection. After many years of cataloguing, conservation, and research, the rediscovery of E.O. Hoppé's extraordinary output can now be seen for the first time in over sixty years.
