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,
