Jacob Mooij probably was taught printmaking by Henri Wils (1892-1967) (<  link) who’d fled from Antwerp to Harderwijk. Mooij is known from less than half a dozen prints in the Antwerp School style of Edward Pellens (1872-1947). His prints show Utrecht and the old academic city of Harderwijk that once saw famous botanist Carl Linnaeus (1707-1778) among its students.
