(b. 1634, Dordrecht, d. 1675, Dordrecht)
Dutch painter, the son of Jacques Levecq, a merchant with ties to Dordrecht's artistic community. Levecq is recorded as having business dealings with the city's confraternity of artists, perhaps a connection gained through Jacob Gerritsz. Cuyp, a fellow member of Dordrecht's Waalse Kerk. Such ties may have encouraged Jacobus to become an artist, and move to Amsterdam to train with Rembrandt. The approximate timing of his instruction is known, for in 1653 Rembrandt signed a document confirming the authenticity of a painting by Paul Bril before an Amsterdam notary, and Levecq undersigned the document, where he is listed as one of Rembrandt's students. By 1655, Levecq had returned to Dordrecht where he became a member of the guild.
Although Levecq made a painting of a cow now in Groninger Museum, Groningen, in the manner of Aelbert Cuyp, he worked primarily as a portraitist. In his first portraits he was clearly looking to Rembrandt's example, employing loose, visible brush-strokes and capturing a penetrating gaze that lends psychological depth to his subject. However, Levecq eventually moved away from this style of portraiture, following more elaborate aristocratic portrait formats in the vein of another former Rembrandt student, Govaert Flinck.
