of their own lives to preserving Caramoor's musical legacy. They established the Center in 1946 and began hosting performances open to the public. Seven years after Walter Rosen died in 1951, the performances had become so popular it became necessary to add the third venue, the Venetian Theater, near the Sunken Garden the Rosens had preserved from the prior estate. The house was opened to public tours in 1970, two years after Lucie Rosen died. Architect Mott B. Schmidt designed a new wing in 1974 to house rooms from the Rosens' New York City apartment and expand the art collection on display. The tent roof and floor were added to the Venetian Theater later to allow its use in inclement weather. The restroom wing was added later. The Sense Circle was created after the dovecote was moved to its following pigeon problems in the late 1980s. There have been few significant changes to the buildings and gardens other than those.

Walter and Lucie Rosen met Theremin at a soirée in 1929 in New York City and were impressed by the inventor and his ground-breaking instrument. Made from a wooden box with two metal antennae, it is played by the movement of hands through their electromagnetic fields without any physical contact. The Rosens offered Professor Theremin the use of one of their three brownstones on West 54th Street, New York, at a greatly reduced rent, as his studio and residence. Lucie Rosen set out to master the instrument, becoming one of Theremin's best pupils as well as his patron and advocate. Her first performance was as a member of Theremin's Carnegie Hall ensemble in 1930. By 1932, Lucie Rosen was performing frequently in New York as a soloist, but it wasn't until 1935 that she made her official New York debut with a recital at Town Hall. “Mrs. Rosen wove with eloquent hands the magical-seeing spell,” the New York World-Telegram wrote, “and the theremin responded to her summons with some of the most strictly
