The Pilat family worked as landscape artists through gardening, floristry, landscape design, and landscape painting. After Carl (Charles) F. Pilat and his brother Ignaz A. Pilat fled the Austrian revolutions of 1848, Ignaz became the chief landscape designer of New York's Central Park. In 1864, Carl and his wife Anna Enzinger Pilat arrived in Sing Sing (Ossining) so that Carl could manage Ignaz's nursery, Lockadian Gardens. In 1867, Carl became the sexton of Dale Cemetery. Carl and Anna had six children and lived on Havell St., most likely in the cemetery's Superintendent's Cottage. Carl F. Pilat Jr. became a well-known landscape designer of parks and estates, and he worked on Nelson Park with Louis, the Pilats' eldest son. Carl Jr. moved away, but Louis remained in Ossining and established his nursery business on Linden Ave. in 1885. The Louis C. Pilat greenhouses flourished for some 70 years, and Pilat's flower shop on Main St. operated into the 1950s. For eldest daughter Ludmilla Pilat, the beauty of the land found expression on canvas. In 1882, American painter Thaddeus Welch met Ludmilla while he was sketching the Devil's Stairs, a rock formation near the cemetery. Welch mentored young Ludmilla, and in 1882, she painted the Jug Tavern of Sparta, a locally treasured work in the collection of the Ossining Historical Society Museum. Although Welch was 23 years her senior, romance followed, and in 1883, sixteen-year-old Ludmilla married Thaddeus. The couple lived in California and became well-known landscape artists. Eventually all three of Ludmilla's sisters joined her in California. Ludmilla died on a return visit to Ossining and is buried here with Louis and his family, her parents, and her maternal uncle, Joseph Enzinger.
