Lawyer before the Supreme Court, businessman, aviation buff and financier.

Educated at Boston Latin, graduated from Harvard in 1871. Taught at Boston prep schools while `reading law in the office of a Boston law firm'. Admitted to the bar in 1876 and thereafter practiced law `in association with' Amoskeag Manufacturing Company.

From 1883 to 1893 acted as private secretary to Admiral George Belknap, his cousin, at Mare Island Naval Yard (San Francisco, Ca.), after which he practiced law in Washington, D.C., primarily court of claims.

In 1895 admitted to practice before the Supreme Court; active in the organization of public (stock) companies; involved in the promotion and management of American Planograph Company and Moore Printing Typewriter Company. From 1896 onwards was full-time manager of the Henry Cary estate in New York.

He seems to have maintained an interest in the business aspects of early aviation. He was a backer of the attempt by Rene Fonck to win the prize for the first solo flight from New York to Paris. Fonck crashed on takeoff in 1926, and the prize was won by Charles Lindberg.

A descendent of Richard Montague (of Hadley, Mass, 1658).
