The owner of what is believed to be the largest individual income in the world began his business life as a poorly paid clerk in a small provincial firm. John Davison Rockefeller was born at Richford, New York, on July 8th, 1839. He was educated in the local public schools. In 1853 his parents moved to Cleveland, Ohio, where, while still a boy, he obtained a position as clerk in a general commission house. When nineteen he went into business for himself by becoming a partner in the firm of Clark & Rockefeller, general commission merchants. Subsequently the firm admitted another partner, and under the title of Andrews, Clark & Co., engaged in the oil business. Its so doing, so it is said, was due to the sagacity of Mr. Rockefeller, who was one of the few men of the period who recognized the future and gigantic possibilities of the oil industry. Later changes were made in the organization of the firm, and in 1865, under the name of William Rockefeller & Co., it built the Standard Oil Works at Cleveland. In 1870 the works were consolidated with others and were then known as the Standard Oil Company. From time to time other oil interests were acquired, and in 1882 all were merged into the Standard Oil Trust. Ten years later, however, the trust was dissolved, and from that time to the present the various companies of which it was composed are operated separately, with Mr. Rockefeller at the head of the business as a whole. CHARLES TYSON YERKES. The Yerkes family is of Dutch origin, and Charles Tyson Yerkes was born June 25, 1837, in Philadelphia, Pennsylvania. He was educated at the Friends’ School and the Central High School in his native city, and entered business life as clerk in a flour and grain commission house. He worked without salary, since, in those days, it was counted a privilege to be connected with first-class houses. Because of his close attention to his duties he was presented with fifty dollars at the end of his first year’s service. In 1859 he opened a stock broker’s office in Philadelphia. During the Civil War he dealt heavily in government, state and city bonds. The panic occasioned by the Chicago fire caught him heavily indebted to the city for bonds sold for it. The authorities demanded settlement; but, being unable to pay in full, he made an assignment. In 1873 he commenced the recuperation of his fortune, and with success. In 1880 he made a trip to Chicago, and, becoming convinced of the opportunities the west offered to financiers, he joined an “improvement syndicate,” of which he later became sole owner. Subsequently he sold his interest in it and opened a banking house in Chicago. In 1886 he obtained control of the North Chicago Railway Company. He added other systems, and finally united several corporations under the title of the Chicago Consolidated Traction Company. Mr. Yerkes was a chief factor in getting the Columbian Exposition for Chicago. He is a devoted lover of art, and possesses
