Lives and works in Frankfurt am Main. He studied photography at the Kunstakademie Düsseldorf with Bernd Becher, who with Hilla Becher was highly influential in the development of the new German photography exemplified by the work of Andreas Gursky, Candida Hofer, Thomas Struth, Thomas Ruff and often referred to as the Becher School. Diergarten has had solo exhibitions throughout Europe, Asia and USA. He has received various fellowships and has had three published books on different projects along the European coast. He shares methodological parallels with the Becher’s conceptually-oriented black and white photographs, including the use of typology as a means to structure his photographic series. His images of vernacular architecture emphasise colour and surface, building a relationship between photography and colour field and constructivist painting. From 2003 to 2005 Diergarten systematically researched beach huts and cabins along the European coast, producing sets of typologies and single images. The continuing extension of this series to the east coast of England has included images of empty shelters and benches, shuttered beachside stalls and boarded up facades.
