He was on the Debate team, Chairman of the Honor System, secretary and later President of his class of 1897.

This is a combined Chelsea Desk Clock timepiece and separate French made Aneroid Barometer set on a single gilt spun brass platform which rests on brass ball feet. Such desk sets were first seen in the Chelsea catalog of 1911. They were offered with 4.5”, 6” and 8.5” dials with Time-Only, House strike and Ships Bell striking movements. Each component was also sold separately or combined on a base and all features used heavy beveled glass and convex back covers with a simple design. The Chelsea timepiece in this set has a simple white dial with Arabic hours, bar minutes, subsidiary seconds @6 marked ‘Chelsea’ and American steel Spade hands. The upper dial carried the name of the retailer, “Black, Starr & Frost”. The single spring clock was wound and set from below the case, hidden from the front view. The top of the brass canister is marked, 1927. The aneroid barometer measured changes in air pressure by creating a vacuum within a thin metal container and by using a series of chains and levers resulted in changes in the movement of a needle on the dial, either with rising or falling pressure. One was then able to see changes from a previous fixed reading taken on the previous day, for instance. Therefore, there were two hands for barometric pressure, one fixed with a prior reading and one moving in the direction of higher or lower pressure. In addition the French barometer also told the temperature in Fahrenheit degrees with a mercury filled thermometer at the base of the dial. The top of the brass canisster case is marked, 1924. . . Paul Naudet was the initial maker of barometers for Chelsea. since Naudet could not keep up with the great demand Chelsea resorted to other companies, e.g. selsi of NYC, taylor Instruments of Rochester Zenith watch company in switzerland and a german source as well. However, the Paul Naudet barometer remained the gold standard for Chelsea.
