Andrew B. Karoly was born in Veranno, Hungary and studied art in Budapest before the outbreak of World War One. After the War ended in 1918 he began to produce paintings and etchings of scenes in Italy, Germany and particularly, France. Before coming to the United States, he studied at the University of Art and Architecture in Budapest and at the Art Academy in Munich and traveled through Italy, Spain, Germany, France, Belgium, and Holland, gathering material for his paintings and etchings.
It is believed Karoly came to live in New York around 1920 and worked during the years of the Great Depression (1930-1939). During the 1930s, Karoly worked art projects commissioned by W.P.A (Works Progress Administration), including several large, public murals. He produced murals for the 1933 Century of Progress Exposition in Chicago and for Bellevue Hospital in New York. At this time he often collaborated with Hungarian/American painter and etcher, Louis Szanto. Today the etchings and paintings of Andrew B. Karoly are included in many American collections, including the San Jose Museum of Art, Delaware Art Museum, National Gallery of Art, Syracuse University Art Museum, The Jewish Museum, Wichita Art Museum, and the Georgetown University Library Art Collection.
