JOHN D. ROCKEFELLER 10¼x14, Sepia photograph of the world's first billionaire shown in a suit and tie from the waist up. Photograph signed: "John D Rockefeller/May 7th 1923", Sepia, overall, 8x10 image, one surface. Merchant and businessman John D.Rockefeller, Sr. (1839-1937) established his first oil refinery in 1863 near Cleveland, Ohio. His enterprise became the largest in the region within three years; he incorporated the Standard Oil Company of Ohio in 1870 and bought out all of his major competitors by 1872. Rockefeller was a shrewd - critics claimed unscrupulous - business man - but the only legal problems he faced were anti-monopoly legislation and litigation, which he resisted through the use of holding companies. Rockefeller was the first billionaire, and the richest man of his time. Adjusted for inflation, he may have been the richest man of all time. From 1885 to 1910, he founded four philanthropic institutions, eventually contributing more than one-half billion dollars. The Rockefeller wealth, channeled through several foundations and trusts, remain major philanthropies.

ORVILLE WRIGHT. Photograph signed: "Orville Wright". B/w, 6¼x4½ overall, image 5x3¼ (one surface). Captioned at lower margin: "First Man-Flight, December 17, 1903/Kitty Hawk, N.C." Orville Wright (1871-1948) and his brother, Wilbur (1867-1912), made aviation history with their Flyer in Kitty Hawk, on North Carolina's Outer Banks, on December 17, 1903. While the Wrights had been testing their gliders on Kill Devil Hill for a number of years, this was their first test of their motorized, heavier-than-air flying machine. At 10:35 a.m., Orville Wright was at the controls of the 21-foot biplane with the 40.3-foot wingspan. The 605 pound craft, powered by a 12-horsepower engine that had four piston cylinders and revved to 1,090 rpm, left the ground, staying aloft for 12 seconds and covering 120 feet at an altitude of ten feet. Later that day, during one of their three test flights, Wilbur also manned the controls, traveling 852 feet in 59 seconds. In 1905, Wilbur and Orville decided to stop flying and tried to market their machine, first offering it to the U.S. government and then flying it in France.

He will undoubtedly recollect my predictions at that time, for him, that having taken the enterprize at its very commencement, and made himself thus early master of all that pertained to it, he would have an experience, possessed by no other, which would enable him to command any position he might choose, not only one of usefulness but I believed also of fortune. I am gratified in believing that he has attained a position, at least of well earned competence if not of fortune, which he richly deserves for his high and honorable personal character, as well as his eminent Skill & perseverance.
