Leading architect of the Amsterdam School and the Expressionist movement.
He worked in Eduard Cuypers' architecture firm from 1903 until 1911; he met famed architects Johan van der Mey and Michel de Klerk during his time with Cuypers.
He designed houses, municipal buildings, bridges, and canals; his masterpiece was the De Bijenkorf Store in The Hague.
He was born in Amsterdam and died in Santpoort; appreciation for his work faded after his death thanks to the Rationalist movement supplanting the Expressionists.
He was born in the same town as fashion designer Ronaldus Shamask.
