Brief Biography-Willem van de Velde the Younger left for Amsterdam at the age of three where Simon de Vlieger mentored him at his Weeps residence. Vlieger was a strong influence on him; however, he developed a unique style and reached his peak in the 1650s. His first known dated work was in 1653, and by 1660 his work was in high demand. His output of marine battle scenes was prolific, and from 1672, several of his works were inscribed ‘in London’. He and his father, Willem the Elder, left that year for England, where they served under the king of an enemy; speculation has it that it was purely for generous remuneration. Willem the Younger’s works had a profound influence on English marine art. Jan de Groot, artist and art dealer, attributed over six hundred paintings to Willem the Younger.
