About the Building: In 1899 Dr. Edward Kellogg Dunham and his wife, Mary, commissioned renowned architect Thomas Hastings of the firm Carrere & Hastings to fashion a French townhouse in the very au currant Beaux Arts style completed in 1901 called Dunham House. A decade later, this historic home was widely considered a pristine example of Hastings’ work and was a large part of why Hastings was then commissioned to design the New York home of Henry Frick in 1912 (The Frick Collection today). Today 35 East 68th Street still sits as a 25’ wide, limestone building which was designated by the New York City Landmarks Preservation Commission in 1981 after being converted into apartments in 1977.
