Ludolf Bakhuizen (28 December 1630 or 1632 – 7 November 1708) was a German-born Dutch painter, draughtsman, calligrapher and printmaker. He was the leading Dutch painter of maritime subjects after Willem van de Velde the Elder and Younger left for England in 1672. He also painted portraits of his family and circle of friends. He was influenced by Willem van de Velde the Elder. Bakhuizen assisted Bartholomeus van der Helst in 1668.
He was an ardent student of nature, and frequently exposed himself on the sea in an open boat in order to study the effects of storms. His compositions, which are numerous, are nearly all variations of one subject — the sea — and in a style peculiarly his own, marked by intense realism or faithful imitation of nature. He moved frequently as he married four times and lived at Haarlemmerstraat, Nes, N.Z. Voorburgwal, Rozengracht, Singel across the Doelen, and at Herengracht 193 (between Oude Leliestraat and Driekoningenstraat) which was sold in 1749.
In his later years Bakhuizen employed his skills in etching; he also painted a few examples each of several other genres of painting, such as portraits, landscapes and genre paintings. Bakhuizen painted portraits of his large circle of friends. These are of lesser artistic value but provide an insight into his good relations with contemporary scholars and literary figures.
