Pittsburgh, and is the largest manufacturer of illuminating and industrial glass in America. This company was in- corporated in 1899, being formed by merging the George A. Macbeth Company and the Thomas Evans Company, the new company afterwards absorbing the American Lamp Chimney Company and a little later the Hogan-Evans Company. The widespread use of petroleum from the oil fields of Western Pennsylvania created a great demand for lamp chimneys and made the production of those chimneys a great industry in itself. In 1869 the firm of Thomas Evans & Company was established. This became the greatest manufacturer of chimneys in the world. They operated the Crescent Glass Works at Eighteenth and Josephine Streets, on the South Side. The production of this firm reached the enormous figure of 12,000,000 lamp chimneys a year, 4,000,000 of which were decorated. This production, laid in line, would reach 1500 miles, and built up as a 10-foot hollow square, it would form a chimney over 9 miles high. Three years later the George A. Mac- beth Co. was established and the chief product of this frm was lead glass chimneys, for which a very great de- mand was established. These two concerns, as previously stated, were merged with their later acquisitions, and the new company took over the patents on the Owens Glass Blowing Machine, which made it possible to increase many fold the production of lamp chimneys and other articles. The most important feature in connection with the con- solidation of these companies, aside from the purchase of the glass blowing machine, was the bringing together of the two men, Mr. George A. Macbeth and Mr. Thomas Evans, one the antithesis of the other in many respects, but both well grounded in the intricate processes of glass-making, one a man of great imagination and the other more con- servative, but admirably fitted by reason of keen business instinct, to direct the financial affairs of the new company. The new company was capitalized at $2,000,000 and grew very rapidly. One of its factories, located at Charleroi,
