Educated at Karlstad from 1895. London in 1897, Wolmar attended the School of Otto Lohr in Germany from 1899. Educated at the school of Schmid-Reutte and at the Royal Academy of Arts in 1900, he was a private pupil of Kristian Zahrtmann from 1902-1908. Wolmar was born in Sweden but lived in Denmark most of his life. Wolmar was highly influenced by Kristian Zahrtmann and belonged to the group of early modernists. Wolmar often worked together with the fellow modernists Karl Isakson and Edvard Weie and together they shared a small studio in Copenhagen. Wolmar worked primarily with landscapes and his oils are often categorised as modern works with a touch of cubism. Wolmar was also influenced by the old masters from the Danish Golden age and like them he preferred to paint nature views in different lights. Unlike the other modernists of his time who worked with strong colour contrasts, Wolmar preferred using few colours, and concentrated on colour nuances instead. Wolmar was very much ahead of his time and won numerous prizes and scholarships that gave him the opportunity to study and work in London from 1897, Germany from 1898-1901. Rome and Terracina, Italy from 1901. Finland from 1904 and at Cagnes-sur-Mer, Paris and northern Italy from 1924-1929.
