Hendrik de Keyser

Dutch sculptor and architect Hendrick de Keyser (15 May 1565 – 15 May 1621) was a Dutch sculptor and architect, who was instrumental in establishing a late Renaissance form of Mannerism changing into Baroque. Most of his works appeared in Amsterdam or elsewhere in the Dutch Republic. He was the father of Pieter and Thomas de Keyser and Willem, and the uncle of Huybert de Keyser, who became his apprentices and all involved in building, decoration and architecture. -- Note from Wikipedia
