After World War II Hanfried Lenz was classified as a "follower" by the denazification process. He started to work as a math and physics teacher in Munich and in 1949 he became an assistant at the Technical University of Munich. He received his PhD in 1951 and his Habilitation in 1953. He worked as a lecturer until he became an associate professor in 1959. In 1969 he finally became a full professor at the Free University of Berlin and worked there until his retirement in 1984.
He was also politically active and in connection with his opposition to the rebuilding of the German army in the early 50s, he became a member of the
Hanfried Lenz is known for his work on the classification of projective planes and in 1954 he showed how one can introduce affine spaces axiomatically without constructing them from projective spaces or vector spaces. This result is now known as the theorem of Lenz. During his later years he also worked in the area of combinatorics and published a book on design theory (together with Dieter Jungnickel and Thomas Beth).
