Hartmut Bärnighausen

Hartmut Bärnighausen (born 16 February 1933 in Chemnitz) is a German chemist and crystallographer. He is well known for establishing the Bärnighausen trees which describe group-subgroup relationships of crystal structures.[1]

Life

Bärnighausen studied Chemistry in Leipzig and received his diploma after a diploma thesis with Leopold Wolf in 1955.[1] In May 1958, he flew from East Germany to Freiburg, where he worked with Georg Brauer.[1] He finished his doctorate in the group of Georg Brauer in 1959.[1] In 1967, he received his habilitation.[1] From 1967 to 1998, he was a professor for inorganic chemistry at the University of Karlsruhe.[1]

Research

His research focused on the following topics:

  • crystallographic group theory in crystal chemistry (Bärnighausen trees)[1]
  • synthesis and characterization of new compounds in including rare earth metals[1]
  • structure refinements of twinned crystals[1]

Awards

He was awarded the Carl Hermann Medal of the German Society for Crystallography in 1997.[2]

gollark: Yes.
gollark: Determinism is outdated. I'm a *super*determinist.
gollark: In this setup, it pushes on the same thing the other magnet is pulling.
gollark: Because the magnet you're holding pushes on you.
gollark: There's a force on the left magnet from the right magnet. There's an equal force on the right magnet from the left magnet. Net force on the body is 0. QED.
