Charles C. Horn
Charles C. Horn (1889-1957) was born in Brooklyn, New York and studied art at the Pratt Institute. He began teaching at the School of Art and Design of the Rochester Athenaeum and Mechanics Institute (a precursor to RIT) in 1921. Previously, he was art supervisor for public schools in Summit, New Jersey, head of the art department of Laidlaw Company (an advertising agency), and art director for Dawley Studios (a motion picture company).
In 1943, he devised the Horn Art Aptitude Inventory. This test was used in art schools, colleges, and universities throughout the country. A resident of the Finger Lakes, Horn retired after teaching at RIT for 33 years in 1954. After retiring, he continued to teach painting one night a week at RIT and in the adult education division of Webster High School.
