Many of Schaldach's paintings and etchings reflect his background as a sportsman. His favorite subjects were wildfowl, anglers with fly rods in rivers, streams and lakes, and game fish in the water. Schaldach was employed by the magazine "Forest and Stream" as a managing editor until the late 1930s. He returned to the magazine, then renamed "Field and Stream," after World War II. In addition to writing many magazine articles about sporting art, Schaldach wrote and illustrated a number of books, including "Fish by Schaldach," "Currents and Eddies," "Coverts and Casts," "Upland Gunning," and "Path to Enchantment: An Artist in the Sonoran Desert," a book about his own paintings of the Sonoran Desert that he completed between 1948 and 1956. He was also the author of a biography of the well-known wildlife artist, Carl Rungius.
Schaldach was a member of the Society of American Etchers, the Independent Society of Printmakers, and the Salmagundi Club of New York. His work has been exhibited at the Chicago Society of Etchers, the Artists for Victory at the New York Metropolitan Museum of Art, the 1939 New York World's Fair, the National Academy of Design, the American Watercolor Society in New York, and in numerous other galleries and museums throughout the country.
