WIRES OF SUICIDE, THEN KILLS HIMSELF;
Chauncey Eldridge, Builder of Wireless Plants, Ends Life with a Bullet.
Body Found in His Office
Wife Informed of Death by His Telegram, Relayed Back From Chicago.
Chauncey Eldridge, an engineer and at one time an international builder of wireless plants, fired a bullet through his brain at his desk in the offices of the Motol Lubricant Corporation, 17 East Forty-second Street, about 6 o'clock last evening. He had suffered from heart trouble, and after an acute attack Saturday had told Mrs. Eldridge: "I'll never have another one of these."
. . . Mr. Eldridge was long active as President of the Federal Holding Company in the construction of wireless plants. He controlled the Poulson wireless telegraph patents, which later were sold to the United States Government in 1918.
Mr. Eldridge was 58 years old and lived at 212 East Fort-eighth Street.
[NOTE: Eldridge's widow, Mabel Baylis Eldridge, married William Crane Ivison on January 27, 1937. She is not interred with Chauncey in the Eldridge-St. George lot in Green-Wood Cemetery.]
