It appears that this hospital went bankrupt and closed at the end of 1975. A story in the NYTimes, Oct. 9, 1975, (p. 45) stated that it had been ordered by a judge to shut down on Nov. 6, but that Ethel Merman and other show biz figures were trying to raise money to aid it. Since its debts amounted to millions, no doubt it was beyond help. There is no later story formally announcing that the hospital had closed. The Oct. 9 story named Roosevelt Hospital and St. Clair's hospital as other nearby hospitals that might take over its business. Perhaps they also took over its records.
It was the result of a merger in 1969 between the French Hospital, at 330 W. 30th, and the Polyclinic, at 345 W. 50th. Acc. to the Times, both had been founded in 1881. The two hospitals evidently had kept their separate buildings, but a few years before 1975 they had agreed to buy the New Yorker Hotel, at 34th st. and convert it to a hospital. Apparently this move is what brought about the bankruptcy.
