German painter. He was the founder of still-life painting in Hamburg where he became a citizen by 1668. His earliest dated trompe l'oeil still-lifes are from 1665. In 1672, Hainz was in Leipzig, where he painted mainly portraits. After a lengthy trial with the Hamburger painters guild from 1667 to 1681, Hainz became an independent master in 1682. Joachim von Sandrart praised him as "Meister in stilligenden Sachen" ("master in motionless objects"). His students were Christian Berentz and Ernst Stuven. Hainz painted in the Dutch still-life tradition of the seventeenth century. He specialized in painting collector's cabinets with precious objects of art. Examples of these paintings are kept in the Statens Museum for Kunst, Kopenhagen, Staatliche Museen, Berlin, and in the Kunsthalle, Hamburg. //
