Abraham de Verwer was probably born in Haarlem, which was where he was living with his wife, Barbara Sillevorts, in 1607. Her will, which a Haarlem notary drew up for her in that very year, identifies her husband as a cabinet maker. When Abraham de Verwer appeared before an Amsterdam notary on January 9, 1617, however, he was identified as a painter. Thus, De Verwer must have learned the art of painting between 1607 and 1617, probably by studying with the famous Haarlem marine painter Hendrick Vroom (1563–1640) before moving to Amsterdam. De Verwer’s early marine paintings of the 1620s reflect the large, brightly colored, and highly detailed depictions of marine battles that characterize Vroom’s work of the 1610s. De Verwer’s son, Justus de Verwer (c. 1625–c. 1685), who was also a marine painter, presumably trained with his father.
De Verwer was extremely successful as an artist, and his large battle scenes soon graced the collections of the Amsterdam Admiralty, the Burgerweeshuis (Amsterdam’s civic orphanage), and the collection of the House of Orange. In the late 1630s he traveled to France, where he made a number of paintings and drawings of French ports and at least four paintings of the Louvre in Paris. In 1638, with the assistance of Constantijn Huygens, secretary to the Prince of Orange, De Verwer sent a number of drawings of French ports to Prince Frederik Hendrik, and in the following year sold him four paintings of French subjects, including two views of the Louvre. In 1642, identifying himself as “Seigneur Abraham de Verwer van Burghstrate,” he acquired a house called “De vergulde Fonteyn” on the Prinsengracht in Amsterdam for 6,500 guilders. He later moved to a house on the Warmoesstraat. He was buried on August 19, 1650.
