Painter, printmaker. After graduating from high school, Hennings left his native Pennsgrove, New Jersey, for five years of study at the Art Institute of Chicago. His training continued with two years at the Royal Academy in Munich. Fellow art students in Munich included Walter Ufer and Victor Higgins. In 1914, at the outbreak of World War I, Hennings returned to Chicago, where he made his living as a muralist and commercial artist. At the urging of former Chicago mayor Carter Harrison, Hennings spent a few months in Taos in 1917. Four years later, he made Taos his permanent home, joining the Taos Society of Artists in 1924. Hennings's favorite subject was the Indian, whom he often posed singly or in groups against a bright foliage curtain. His compositions, featuring stylized line, decorative patterns, and warm colors, won him twelve national prizes between 1916 and 1938.
