The painter-collector P.G. Westenberg was apprenticed to Jan Hulswit in Amsterdam at a young age. Together with his teacher he made a study trip in 1816 and 1817 through Gelderland and in Germany along the Rhine and Ruhr. He mainly painted romantic landscapes, also with moonlight, city and ice views. At the age of 47, Westenberg was appointed director of Paviljoen Welgelegen in Haarlem, the then national museum of 'contemporary' art. In 1857 he left for the Dutch East Indies for an administrative position. His work never prevented Westenberg from continuing to paint, although his production did decrease after 1840.
