Briarcliff Manor maintains strong ties to its history and traditions. During Briarcliff Manor's 1952 semicentennial, nine people served on the Historical Committee and published a village history book. In March 1974, after the mayor appointed twelve people for a 75th anniversary committee, the committee began by forming the Briarcliff Manor-Scarborough Historical Society (BMSHS). The historical society published an updated village history (A Village Between Two Rivers: Briarcliff Manor) in 1977, marking the 75th anniversary of the village. The historical society was initially located at the since-demolished Briarcliff Middle School building; it later moved to the second floor of a realty building on Pleasantville Road, and moved back to the school building after it was leased by Pace University.[5](p195) On March 21, 2010, the BMSHS was given a permanent location at the Eileen O'Connor Weber Historical Center, established as part of the expanded Briarcliff Manor Public Library.[55] Members of the historical society joined the nine-member Centennial Committee in 2002 to organize events for Briarcliff Manor's centennial.[21]
The Centennial Committee and BMSHS helped organize several events for the village's 2002 centennial celebration, including the Centennial Variety Show at the Briarcliff High School auditorium in a sold-out two-night run on April 26–27, 2002.[7] The two-act show consisted of interpretations of village life by village organizations and a revue of Briarcliff Manor history in skits and songs.[21] Other society-sponsored events have included tours of homes and churches, bus tours, Hudson River cruises on historic boats such as the M/V Commander (built in 1917 and listed on the national and state registers of historic places), dances, antique-car exhibits, day trips to historic points of interest, art exhibits and events with authors and elected officials.[55]
