OBITUARY
FREDERIC G. ELDRIDGE
Frederic G. Eldridge, who has been for many years widely known in financial circles, first as a member of the Stock Exchange and of late years as President of the Knickerbocker Trust Company, died at the Hotel Vendome Sunday morning from heart disease. . . . The funeral services will be held at the Calvary Protestant Episcopal Church in Fourth-avenue to-morrow, the Rev. Dr. Henry Y. Satterlee, the rector, officiating.
Mr. Eldridge was born in this city fifty-two years ago, and from the time of his majority was interested in commercial life. When twenty-four years old he went to India and remained to become a member of the mercantile firm of Atkinson, Tilton & Co. of Calcutta and of the Bengal Council, a governing body appointed by the Governor General of Bengal. He was the only American who ever held such a position. Ten years ago he returned to this city and became a member of the brokers' firm of Wharton & Eldridge. While a member of the stock exchange he was prominent in several large financial operations, and was conspicuous during various panics in Wall-street for his conservative council and conduct. At the time of the organization of the Knickerbocker Trust Company in 1884 he became one of the largest stockholders and its President, and it was mainly through his untiring business energy that the institution has reached its present eminence. During its existence Mr. Eldridge had not alone been its President, but the chief mover of its largest transactions. Mr. Eldridge was a member of the Union Club, and was one of the most popular of its regular habitués. He was a man of much wit and an accomplished conversationalist. . . .
Mr. Eldridge leaves a widow, three sons, and two daughters. One of his sons, Chauncey, is in Mexico.
