Willem de Keyser (architect)

Willem Hendrickszoon de Keyser (1603 – after 1680) was a Dutch Golden Age architect and sculptor primarily active in Amsterdam and London.

[2][3] He also sculpted reliefs for Amsterdam's new town hall (now the Royal Palace) and for the monumental tombs of the Dutch naval heroes Maarten Tromp, Michiel de Ruyter, and Jan van Galen.

Around 1623 he left Amsterdam to settle in London, where he found employment with his brother-in-law, the English architect Nicholas Stone, who had married Willem's sister Maria.

He assisted Jacob van Campen in designing and building Amsterdam's grand new town hall (now the Royal Palace) as well as the spire of the adjacent Nieuwe Kerk church.

He must have returned to Amsterdam not long thereafter, as he was working in 1678 on a monumental tomb for Michiel de Ruyter in the Nieuwe Kerk, over which he brought a case to court in 1680.
