DARCEY, John S., physician, born in Hanover, Morris County, New Jersey, 24 February 1788; died in Newark, New Jersey, 22 October 1863. His father was a physician, and with him he studied and succeeded to his large practice, he was a member of the state legislature in 1819. In 1832, on the first appearance of Asiatic cholera in this country, he removed to Newark, New Jersey, and by his skill in the treatment of that disease, and his devotion to his patients and sympathy with their sufferings, attained a practice more extensive and exacting than any other in the state, which finally impaired his remarkably vigorous constitution. In 1835-'41 he was U. S. marshal for New Jersey. He exerted great influence in his party in the state, but was averse to holding office. On the incorporation of the New Jersey railroad company he was elected its president, and held the office till his death, a period of over thirty years. In 1849, his health failing, he made the overland journey to California, but his health was rather injured than benefited.
