(17 December 1806 - 12 February 1875) was a German landscape and marine painter and graphic artist. He and his contemporary, the painter Christian Morgenstern, were pioneers in Hamburg of early Realism in painting.
As son of a bookkeeper to a Hamburg merchant, Vollmer grew up in humble circumstances. Determined to become a painter against the wishes of his father, he became an apprentice to the brothers Suhr who owned a graphic workshop producing panorama prints. For one and a half years Vollmer travelled throughout Germany with one of the brothers, Cornelius Suhr, as had been Morgenstern before him. In 1826 he was introduced by the Hamburg art-dealer Ernst Harzen to the wealthy aristocrat and supporter of the arts, Carl Friedrich von Rumohr, who was patron to many young Hamburg artists among them Morgenstern and Otto Speckter. Probably on Rumohr advice Vollmer completed his studies under Christoffer Wilhelm Eckersberg at the Royal Danish Academy of Fine Arts in Copenhagen. He then moved to Munich from where he undertook journeys to Lake Konstanz, to the Austrian and Swiss Alps, to Venice, to Le Havre and to the Netherlands.
In 1839 Vollmer returned to Hamburg and settled there. One of his sons, Johannes Vollmer, became a prominent architect of protestant churches; a grand-son was the art historian and encyclopaedist Hans Vollmer who, for many years, edited the Thieme-Becker Kenstler Lexikon.
Vollmer became blind in 1866.
