A sculptor, not that very well known outside Germany, but a sculptor who nevertheless has its own museum. The Wilhelm Lehmbruck museum in Duisburg has a nice collection, but the Lehmbruck name is kept alive by practically all large museums in Germany.
Personally i do not know the fascination , because in my opinion Lehmbruck has not freed himself of making classical sculptures. He did not make the full transition into modern sculpture as for instance Giacometti did. Perhaps this is explained from the short life he had and he did not have the time to develop himself completely. If you look at that way, Lehmbruck took the first steps into modern sculpture but never had the time to complete his ideas on modern sculpture. http://www.ftn-books.com has some nice Lehmbruck publications available.
