Jan Gratama

Jan Gratama (17 August 1877 – 12 December 1947), was a Dutch architect.

He was born in Groningen and was the younger brother of the artist and museum director Gerrit David Gratama. He studied at the Polytechnical School of Delft and became an amateur portrait artist like his older brother. He was an artistic advisor to his sister Lina, who also became a portrait artist, and became known for her copies of the works in the Mauritshuis and the Gemeentemuseum Den Haag.

In 1908 he established an architecture bureau in Amsterdam, where he worked with Berlage and others in the style of the Amsterdam School. His partners in his architect bureau were Gerrit Versteeg from 1914 and Jan Willem Dinger from 1930, who continued the bureau after Gratama died in 1947.
