Abraham Mignon
Marrel's stepdaughter Maria Sibylla Merian (1647–1717), daughter of the engraver Matthew Merian, who lived with Marrel and thus studied with Mignon, achieved distinction as a flower painter. Besides Merian, his other pupil was Ernst Stuven. He left two daughters when he died; Catharina and Anna.
Maria Sibylla Merian
Merian was one of the first naturalists to observe insects directly. Merian collected and observed live insects and created detailed drawings. In her time insects still had a reputation as "beasts of the devil" and the process of metamorphosis was largely unknown. While a handful of scholars had published empirical information on the insect, moth and butterfly life cycle, the widespread contemporary believe was that they were "born of mud" by spontaneous generation. Merian documented evidence to the contrary and described the life cycles of 186 insect species.
