Aert Schouman or Aart Schouman was an 18th-century painter, now better known as a glass engraver, from the Dutch Republic.
Schouman was born in Dordrecht. When 15 years old he served as apprentice to the Dordrecht artist Adriaan van der Burg, along with Cornelis Greenwood, the son of his teacher for glass engraving, Frans Greenwood, inventor of the stipple style, which Schouman also worked in. Schouman was unusual among painters in that he kept a detailed diary of his professional life from 16 October 1733 to 16 November 1753. He took on his first art pupil in 1733 and continued teaching for the rest of his life. From 1742 until 1792 he was head of the Dordrecht Guild of St. Luke, and in 1751 he became regent of the Hague drawing school associated with the Confrerie Pictura of The Hague. In 1736 he founded the "Brotherhood" of the Confrerie in The Hague, a fraternity of amateur art lovers from Dordrecht and environs, of which he was headman during the years 1752–1762.
Schouman was a leading artist in Zeeland between 1735 and 1785. During that period he lived and worked in Dordrecht, The Hague and Middelburg and taught pupils in Dordrecht and The Hague.
