James Arthur

Mr. Arthur is an enthusiastic scientist, a successful inventor and extensive traveler, who has for years been making a study of clocks, watches, and time-measuring devices. He is not only a great authority on this subject, but his collection of over 1500 timepieces gathered from all parts of the globe has been pronounced the finest collection in the world. Mr. Arthur is a pleasing exception to the average business man, for he has found time to do a large amount of study and research along various scientific lines in addition to conducting an important manufacturing business in New York City, of which he is president. Mr. Arthur is 67 years of age.—H. H. Windsor.
