Jacob Ritsema

Jacob Coenraad Ritsema (10 June 1869, Haarlem - 15 December 1943, Laren) was a Dutch landscape, portrait and genre painter; associated with the Düsseldorfer Malerschule and the Haagse School.

He was the eldest of four children born to Coenraad Ritsema (1834–1916), a printer who had trained as a lithographer in Düsseldorf, and his wife, Jeanette, née Moulijn, originally from Rotterdam.

His brother, Johan, was sent to Paris to be a lithographer's apprentice, while he went to Düsseldorf at the age of fifteen, to enroll at the Kunstakademie.

His primary instructors were Heinrich Lauenstein, Hugo Crola, Johann Peter Theodor Janssen and Adolf Schill.

He took some students and was a member of numerous artists' organizations, such as the Kunstenaarsvereniging Sint Lucas [nl] and Arti et Amicitiae, in Amsterdam, as well as the Haagse Kunstkring and the Pulchri Studio.
