Though often overlooked due to his association with Frederick Law Olmsted, Calvert Vaux is an important figure in American architecture in his own right. A classically-trained architect, talented artist, and strong advocate for public parks, he had already completed major projects before working with Olmsted on Central Park and Prospect Park. To mark Vaux’ 200th birthday, we will examine his distinctive architectural style on display in Prospect Park, paying special attention to structures such as the Well House, Concert Grove Pavilion, and the park’s many arches. We will also examine Vaux’ legacy of designing buildings and landscapes for the public good, including museums, parks, and housing.
