Bretislav Friedrich investigated orientation of cooled molecules in strong electric fields with Dudley Herschbach. Restriction of angular motion produces pendulum-like rotational states, connecting low temperature with control of a molecule’s spatial orientation.[ref]
Spatial orientation of molecules in strong electric fields and evidence for pendular states by Bretislav Friedrich and Dudley R. Herschbach. 1991, abstract: rotational cooling, spatial orientation and restricted angular motion

Bretislav Friedrich is not widely recognized in popular culture or mainstream media, so there may not be a well-known public figure by that name as of my last knowledge update in October 2023. It could refer to a lesser-known individual, perhaps in a specific field such as academia, the arts, or business, or it could be a fictional character or a name relevant in a more niche context.
