From Infogalactic: the planetary knowledge core
John Charles Martin was a newspaper publisher who, beginning in 1913, ran the newspapers purchased by his step father-in-law Cyrus Curtis, including the Public Ledger, the New York Evening Post, the Philadelphia Inquirer and four others.[1][2] In 1931, an insurance industry magazine published a listing of Americans carrying the greatest amount of life insurance; Martin was second on the list with $6,540,000 in insurance, after Pierre Samuel du Pont with $7 million. [3] Martin's former estate in Wyncote, Pennsylvania now houses the Reconstructionist Rabbinical College.
