PITTSBURGH'S role as the initiator of the age of "big business" and its success at building up industry to a size and efficiency never before attained anywhere has made it the synonym for "materialism" in the minds of people the world over. No Pittsburgher is inclined to minimize the achievements of his city in the way of solid attainments-especially when he is confronted daily by the towering chimneys of the hundreds of factories engaged in the fabrication of steel, aluminum, glass, and electrical equipment, and by the evidences of the tributary empire of coal mines, forests, and farms. But anyone who knows his Pittsburgh is conscious of a powerful undercurrent of idealism, a current that is stronger perhaps than in any other American city. Pittsburgh's industrialists have diverted much of their wealth into channels and institutions whose returns are measured, not in dollars and cents but in the spiritual and intellectual growth of the community and of the nation. The philanthropic tradition is ingrained in Pittsburgh history from the days when it was a mere village, and scores of the men now remembered by their posterity only as successful merchants or manufacturers or financiers looked upon themselves chiefly as humanitarians and only secondarily as businessmen.
