Dutch painter, son of the engraver Willem Jacobsz Delff, and grandson of the Delft portraitist Jacob Willemsz Delff I. He was trained in the workshop of his other grandfather, Michiel Jansz. van Miereveld, another significant portrait painter in Delft at the beginning of the seventeenth century. After the death of Miereveld in 1641, the young Delff took over and lead the prosperous workshop which produced many portraits in the style of Miereveld. //
