OttHeinrich Keller was a German mathematician who worked on algebraic geometry and topology.
Mathematical Profile (Excerpt):
 Keller then went to the Technical University of Charlottenburg in Berlin where he was appointed as assistant to George Hamel.
 In 1949 he published Zu einem Satze von H W E Jung über ganze birationale Transformationen der Ebene Ⓣ(On a theorem of H W E Jung on all birational transformations of plane) and, by a strange coincidence, following the retirement of Heinrich W E Jung from the chair of mathematics at Halle, Keller was appointed to Jung's chair at the Martin Luther University of HalleWittenberg in 1951.
 In 1954 Keller published his first book Geometrie der Zahlen Ⓣ(Geometry of numbers) which contained many of his contributions to the topic.
 Keller retired in 1971 from his professorship in Halle.
Born 22 June 1906, Frankfurt (Main), Germany. Died 5 December 1990, Halle, Germany.
