Frank E. Estabrook, 1860-1918, was a Newburgh native, who after attending Newburgh schools, studied architecture at Boston Polytechnic school and returned to Newburgh in 1891 to begin his career. One of his first commissions was the design of Liberty St. School. Designs for the Broadway School, Newburgh YWCA, Quassaick Bank, and Wheelmen's Club followed. A book of photographs and sketches of his designs is available on NY Heritage.
