a Dutch Golden Age portrait painter who had been a pupil of Gerard Dou and is known as one of Leiden's fijnschilders. According to Houbraken, his teacher was Gerard Dou, who he imitated so well that many of his works were later misattributed to him. He was rather introverted and very methodical and conscientious, spending months on his works and striving for perfection. Houbraken wrote that Slingelandt took 3 years to paint a family portrait for the gentleman Mr. Meerman, and that he took 6 weeks to paint the lace of one child's bib.
