When he is mentioned at all, it is most often in conjunction with Frans Hals or Judith Leyster, both prominent Haarlem painters at the peak of the city's artistic greatness in the 17th century. Jan Miense Molenaer (c 1610-1668) was in fact the former's putative pupil, the latter's husband (they had five children, though only two survived to adulthood), and himself a painter of some reputation; he was good enough to be called a "little master" and productive enough to have owned simultaneously three houses. Still, he was chronically in debt, a fact that accounts perhaps for his large output but also for its uneven quality.
