Peter Keetman was born in 1916 as the son of a wealthy family in Elberfeld. His father Alfred Keetman, married to Käthe Simons, was consul and bank director of the banking firm J. Wichelhaus P. Sohn.  The house Keetman, which was abolished in 1981, was his birth and parents’ house.
He attended the Bayrische Staatslehranstalt für Lichtbildwesen ( State Technical Academy for Fotodesign Munich ) from 1935 to 1937. Afterwards, he assisted for one year with the industrial and portrait photographer Gertrud Hesse in Duisburg and in the studio of the industrial photographer Carl-Heinz Schmeck in Aachen .
In 1940 he was summoned to defend himself, served as a soldier with the railway pioneers, and returned to the war in 1944, severely injured. After some years of assistantship and fellowship, he took his master’s test in Munich in 1948 . Keetman was a founding member of the fotoform group in 1949 and, as a freelance advertising photographer in the 1950s, influenced the direction that New Photography took.
One of his most famous works is a series about Volkswagen , where he exhibited very interesting and at that time revolutionary graphic views on assembly line technology, piles of metal parts and technical details during the construction of the beetle in the plant at the Mittellandkanal without order . His trademark was very detailed, introverted photos that are often close to the graphics and show a certain severity of emotion.
In the middle of 2016 the Museum Folkwang, together with the FC Gundlach Foundation, devoted the photographer on the occasion of his 100th birthday under the title of Designed World. A photographic work of art (3 June to 31 July) a comprehensive retrospective. Starting in November 2016, this exhibition will take place for three months at the House of Photography in Hamburg . 
From 1948 Keetman is represented with pictures and portfolios in all relevant German photo magazines, later also in some international. In addition to this, many publications and illustrations in periodicals dealing with architecture, industrial photography, design, or graphics are the main themes of this book.
In the 3 Volumes on Subjective Photography, edited by Otto Steinert, Keetman’s works have a fixed and stylistic place. The same applies to the yearbooks The German photo (Editor Wolf Strache ) where Keetman is regularly published 1955-1979. Due to his participation, the exhibition catalogs of the Gesellschaft Deutscher Lichtbildner (GDL) have been a reliable reference point for his paintings since 1957.
