Kramer studied physics at the University of Münster, the University of Tübingen, the University of Bristol and the University of Marburg. He received his PhD in 1964 in Marburg and in 1968 his Habilitation
in Tübingen. He was a postdoc at the UNAM in Mexico City, where he collaborated with Marcos Moshinsky.
He was a professor at the Institute for Theoretical Physics in Tübingen from 1970 until 1998 when he retired. He has also served as a Dean and a Vice President at the University of Tübingen. Kramer married in 1962 and has two children.
More recently, Kramer has become interested in cosmology and three-dimensional space forms. His scientific œuvre contains more than 200 publications.[4]
