The Charles Hosmer Morse Museum of American Art houses the world's most comprehensive collection of works by Louis Comfort Tiffany, as well as a major collection of American art pottery and representative collections of late-19th and early-20th century American paintings, graphics and decorative arts. The museum's collections were built over a half century by Jeanette Genius McKean and her husband, Hugh F. McKean; founded in 1942, the museum was named for Mrs. McKean's industrialist grandfather. The extensive collections are based on major windows and architectural elements acquired from Tiffany's fire-ravaged Long Island estate and the elements of his 1893 chapel, built for the World's Columbian Exposition. The complete chapel has been reassembled at the museum, and open to the public for the first time in over 100 years. Tours are available during public hours; groups by reservation. Open Tuesday-Sunday, closed Mondays.
