Career
According to January van Gool he was an avid gardener and his love of flowers made him become a pupil of Constantijn Netscher so that he could paint the flowers and other plants in his garden. He had high hopes of painting more for the elector, but his patron died the same year, so Coenraet returned to the Netherlands. According to the RKD he was trained in the Confrerie in the years 1698-1699 and first became a member there in 1711.
His pupil was Pieter Terwesten.
