Alexander Johnston Cassatt, one of the greatest of the Pennsylvania Railroad presidents, and perhaps the most far-seeing and resourceful of all our captains of industry of the present generation, was born here. James McCrea, the present wise and conservative president of that road, lived here for twenty years. Andrew Carnegie, Henry Phipps, and Henry C. Frick were the strongest personalities who grew up with the Carnegie steel interests. George Westinghouse, whose inventive genius, as shown in his safety appliances, has so greatly reduced the hazards of railway travel and of operation, has long been one of the industrial and social pillars of the community. John A. Brashear, astronomer and educator, the maker of delicate instruments, is a well-beloved citizen. Pittsburgh ranks high as a banking center. She is the second city in the United States in banking capital and surplus, and leads all American cities in proportion of capital and surplus to gross deposits, with 47.1 per cent., while Philadelphia ranks second with 26 per cent. In 1906, there were one hundred and seventy-nine banks and trust companies in the Pittsburgh district with a combined capital of $72,058,402, and a surplus of $87,044,622. The gross deposits were $395,379,783, while the total resources amounted to $593,392,069. Pittsburgh, with clearing-house exchanges amounting to $2,640,847,046, ranks sixth among the cities of the United States, being exceeded by the following cities in the order named: New York, Chicago, Boston, Philadelphia, and St. Louis, and often on a given day exceeds those of St. Louis.
