August Jerndorff was an influential Danish painter who combined the national landscape tradition with an international outlook inspired by the leading European art movements of his time. Born in Oldenburg, Germany, he entered the Royal Danish Academy of Fine Arts in Copenhagen in 1863, where he studied until 1868. He later trained under the renowned landscape painter P.C. Skovgaard, and in 1871 he was awarded the Academy's Lesser Gold Medal in recognition of his artistic talent.
Like many artists of his generation, Jerndorff broadened his artistic horizons through extensive travel. He spent long periods in Italy and furthered his studies in both Paris and Munich. His international perspective led to his participation in the World's Fair in Vienna in 1882, where he exhibited alongside the architect and designer T.H. Bindesbøll.
Jerndorff made his exhibition debut at Charlottenborg in 1866 as a landscape painter, but his work later expanded to include portraits and religious subjects, including altarpieces for Danish churches. He also exhibited at the Artists' Autumn Exhibition and, for a period, at Den Frie Exhibition, reflecting his prominent position in the Danish art world of his day.
Today, his works are represented in numerous Danish museum collections. He also worked as a book illustrator, notably contributing illustrations to Holger Drachmann's Troldhøj. Alongside his artistic career, Jerndorff held several important positions of trust, serving as a member of the Academy Council and later as a professor at the Royal Danish Academy of Fine Arts - evidence of his lasting influence on Danish art and art education during the second half of the 19th century.
