Property of the original German family Willhem van de Velde Le Jeune: Willem van de Velde was baptised on 18 December 1633 in Leiden, Holland, Dutch Republic. A son of Willem van de Velde the Elder, also a painter of sea pieces, Willem van de Velde, the younger, was instructed by his father, and afterwards by Simon de Vlieger, a marine painter of repute at the time, and had achieved great celebrity by his art before he came to London. By 1673, he had moved to England, where he was engaged by Charles II, at a salary of £100, to aid his father in taking and making draughts of sea-fights, his part of the work being to reproduce in colour the drawings of the elder Van de Velde. He was also patronised by the Duke of York and by various members of the nobility.[1] He died on 6 April 1707 in London, England,[1] and was buried at St. James’s Church.
