From 1846 to 1850 he studied painting under the St Louis artist Leon de Pomarede (1807–92). In 1852 he continued his studies at the Kunstakademie in Düsseldorf, where he worked with Josef Fay (1813–75) and Emanuel Gottlieb Leutze until about 1856.

Wimar joined a party of the American Fur Trading Company and made several journeys between 1858 and 1860 up the Mississippi, Missouri and Yellowstone rivers in search of Indian subjects. His painting, the Buffalo Hunt (1860; St Louis, MO, Washington U., Gal. A.), became one of the original works in the collection of the Western Academy of Art. In 1861 Wimar was commissioned to decorate the rotunda of the St Louis Court-house with scenes of the settlement of the West (mostly destr.).
