Hendrick de Keyser, Dutch sculptor and architect (died 1621)

Hendrick de Keyser was a Dutch sculptor, merchant in Belgium bluestone, and architect who was instrumental in establishing a late Renaissance form of Mannerism changing into Baroque. Most of his works appeared in Amsterdam, some 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.
