He was born on January 3, 1860, to Henry Clay Hall Sr. and Amanda Harwood Ferry in New York City.
This, in combination with the death in November 1913 of commissioner John Hobart Marble of California following an attack of acute indigestion, gave President Woodrow Wilson two seats to fill on the Commission.
This position was upheld by the Supreme Court[2] In 1921, Hall was reappointed for another seven-year term by President Harding.
In late 1927, Hall submitted his resignation to President Calvin Coolidge, effective on the appointment of a replacement.
He was survived by his second wife, the former Alice Munsell Sweetser of New York, whom he had wed in 1905, by their daughter, and by four children by his first marriage to Mary Bacon Barstow, who had died in 1901.
