According to the RKD he was a son and pupil of the painters
Jan van Os and
Susanna de la Croix, and a brother of the painters
Pieter van Os and
Maria Margaretha van Os. In 1809 he won the first prize of the Society
Felix Meritis in Amsterdam for a still life in which genre he later specialized. Van Os became
Ridder in de orde van de Nederlandse Leeuw in 1812. From 1816 to 1820 he worked in Amsterdam. In 1822 he moved to Paris, where he worked for the
Sèvres porcelain factory. He painted landscapes, but was, like his father, best known as a painter of flowers. Starting in the 1830s he spent his summers in
Haarlem, where he continued working on flower illustrations for the "
Flora Batava" edited by
Jan Kops. He is not to be confused with the son of his brother Pieter, also a painter called Georgius Jacobus Johannes van Os, but who lived from 1805 to 1841 and continued the family painting tradition. ==References==
