Leroy Ireland (1889-1970) was an art dealer and painter in New York and Philadelphia. Ireland is best know for his research on the works of landscape painter George Inness (1825-1894), culminating in a catalogue raisonne of his work.
Ireland began his career as a painter, studying with Thomas Eakins at the Pennsylvania Academy of Fine Arts and exhibiting in many shows during the 1920s. He moved to New York and became an art dealer and appraiser. During that time he also studied and became an expert in the work of George Inness, specializing in the authentication of works held by galleries, museums, and private collectors. After nearly 30 years of research, his book The Works of George Inness: An Illustrated Catalogue Raisonne was published by the University of Texas Press in 1965.
