"Doctor" John Clarke (1773–1846) was an American businessman who played a major role in the development of Saratoga Springs, New York, in the 1800s.
Clarke built a doric pavilion to cover Congress Spring, which was torn down in 1876 when Frederick Law Olmsted redesigned the park and reconstructed in the 1970s.
[3] Clarke planned and named Circular Street in Saratoga Springs,[1] and in 1832 he built a Greek Revival mansion there overlooking Congress Park.
Clarke began to accumulate land east of Congress Park from the time he arrived in Saratoga Springs.
[7] Eliza first married Isaac Thayer and after his death in 1852 Cornelius Sheehan, and continued to occupy the house on Circular street.
