Theodorus (Theo) Bitter (December 16 1916 – February 13 1994 in The Hague) was a Dutch graphic artist, painter and draftsman. He also made monumental art, designed textiles and illustrated books.
Bitter was educated at the Royal Academy of Arts in the Hague. From 1946-1960 he taught at the same academy. He worked in The Hague, Oslo and Lecce. In The Hague he resided for many years at the Artiestenhof in Trompstraat.[1]
He painted many family portraits and his watercolor paintings were realist. His landscapes and figures reflected an abstract expressionist style. Bitter co-founded the artistic group Hague Verve with Dirk Bus and was a member of the Pulchri Studio.
Bitter taught Margreet van Dulmen, Hubert Herbergh, Leonie Kording, Ronnie Meerts, Henry Oostenbrink, Piet Smissaert and L.D. Verkouteren.
