In the late 1800s, John Donovan lived at 144 St. Marks Avenue (left) and Thomas E. Wheeler lived at #138 (far right). All of the Neo-Grec style brownstones were designed by architect Marshall J. Morrill and constructed in the 1880s, at a time when speculative residential development in Prospect Heights increased in anticipation and reaction to the opening of the Brooklyn Bridge in 1883.
