Willem Bartel van der Kooi was a prominent Dutch portrait painter born on March 13, 1768, in the small village of Wanswerd in Friesland, the Netherlands. He showed an early talent for art, which was recognized and encouraged by his family. As a young man, he moved to Amsterdam to further his education and training in painting. In Amsterdam, Van der Kooi was influenced by the work of Dutch masters of the Golden Age, and he studied under the portraitist Wybrand Hendriks.
Van der Kooi's work quickly gained attention for its detail, composition, and the psychological depth he brought to his portraits. His style was characterized by a fine attention to the textures of fabrics and the interplay of light and shadow, a testament to the influence of his Dutch predecessors.
By the late 18th century, Van der Kooi had established himself as a sought-after portraitist in Friesland. He was particularly known for his portraits of the Frisian elite. In 1791, he was commissioned to paint a portrait of the Frisian stadtholder Willem V of Orange-Nassau. This commission was a significant milestone in his career and helped to solidify his reputation as a master portrait painter.
Throughout his career, Van der Kooi remained largely in Friesland, where he contributed to the cultural life of the region. He became a teacher and a mentor to younger artists, imparting the skills and knowledge he had accumulated over the years. His influence extended beyond his own work to the development of a regional school of painting that persisted into the 19th century.
Willem Bartel van der Kooi continued to paint until his later years, leaving behind a considerable body of work that provides insight into the social and cultural life of Friesland during his time. He passed away on February 11, 1836, in Leeuwarden. Today, his works are held in various collections, including museums in the Netherlands, and are celebrated for their contribution to Dutch portraiture and the cultural heritage of Friesland.
