Hendrik Nicolaas Werkman
Hendrik Nicolaas Werkman was an experimental Dutch artist, typographer and printer. He set up a clandestine printing house during the Nazi occupation and was shot by the Gestapo in the closing days of the war.
Werkman was born in Leens, in the province of Groningen. He was the son of a veterinary surgeon who died while he was young, after which his mother moved the family to Groningen. In 1908, he established a printing and publishing house there that at its peak employed some twenty workers. Financial setbacks forced its closure in 1923, after which Werkman started anew with a small workshop in the attic of a warehouse.
