possible student, as does her husband, the painter Jan Miense Molenaer. In the 19th century, his technique influenced the work of impressionists and realists including Claude Monet, Édouard Manet, Charles-François Daubigny, Max Liebermann, James Abbott McNeill Whistler, Gustave Courbet, and in the Netherlands, Jacobus van Looy and Isaac Israëls. Lovis Corinth named Hals as his biggest influence. The post-impressionist artist Vincent van Gogh wrote to his brother Theo: 'What a joy it is to see a Frans Hals, how different it is from the paintings – so many of them – where everything is carefully smoothed out in the same manner.' Hals chose not to give a smooth finish to his painting, as most of his contemporaries did, but mimicked the vitality of his subject by using smears, lines, spots, large patches of color and hardly any details. Legacy The 1911 Encyclopædia Britannica has an article on Frans Hals by "P.G.K.", who observes: Hals's reputation waned after his death and for two centuries he was held in such poor esteem that some of his paintings, which are now among the proudest possessions of public galleries, were sold at auction for a few pounds or even shillings. The portrait of Johannes Acronius realized five shillings at the Enschede sale in 1786. The Portrait of Willem van Heythuysen at the Alte Pinakothek sold in 1800 for £4: 5s (£4.25 in decimal notation). Nevertheless, Hals's art did not go altogether unappreciated in the time between his death in 1666 and the 1860s. In his Groote Schouburgh (1718–1721), Arnold Houbraken recorded Hals's life and praised his style, adding that the figures in one of the large group portraits: ... zoo kragtig en natuurlyk geschildert zyn, dat zy de aanschouwers schynen te willen aanspreken ("... are painted so powerfully and naturally, they seem to want to talk to us"). Dutch artists known to have admired Hals enough to make copies of his paintings include Cornelis van Noorde (1731–1795) and Wybrand Hendricks (1744–1831). Empress Catherine the Great (reigned 1762–1796) acquired ten Hals works for her collection. Jean-Honoré Fragonard (1732–1806) visited the Alte Pinakothek to copy Hals's work, and Hals's influence is apparent in Fragonard's portraits de fantaisie. Antoine Watteau (1684–1721) made study sketches after Hals. At the Royal Academy in London, Joshua Reynolds (1723–1792) lectured on Hals in 1774, praising his handling of faces and the consequent remarkable individuality of his portraits. Reynolds was less enthusiastic
