Mr. Carnegie has frequently challenged public notice by acts of philanthropy. He has given free baths and a free library to his native town of Dunfermline, a histological annex, known as the Carnegie laboratory to Bellevue Hospital, New York; a free library and music hall to Allegheny City; a free library and music hall, costing more than $1,000,000, to Pittsburgh; a free library to Edinburgh, Scotland, and similar donations to Braddock and other places where he has business interests. He has a fondness for literature, has written several books, of which "Triumphant Democracy; or Fifty Years' March of the Republic" is the most pretentious, and at one time controlled eighteen English newspapers in the Radical interest. Mr. Carnegie married late in life and has since maintained establishments in New York and at Cluny Castle, Scotland, rarely visiting his mills. Estimates of Andrew Carnegie's character vary widely. To those associated with him in business he is known as a firm and considerate friend, quick to discern ability and generous in rewarding it. As an employer of labor he bore a high reputation for liberality and sympathetic regard for the well-being of his employees until the occurrence of the trouble at Homestead in 1892. How far he was personally chargeable with responsibility for Mr. Frick's iron-handed policy in that affair has never been positively determined; but it is certain that the relentless spirit shown by Mr. Frick cost Mr. Carnegie much of his popularity. The connection of Henry Clay Frick with the Carnegie iron and steel industries, did not begin until Andrew Carnegie had reached the zenith of his success. Mr. Frick, however, had already carved his way to wealth along a different line, and was himself a millionaire. His success was gained in coke, and he came to be known as "the Coke King." Coke is indispensable to the manufacture of steel, but for a long time its production remained a separate industry. The Connellsville region, lying about fifty miles south of Pittsburgh, was occupied by a number of small producers, whose cut-throat mode of competition was highly advantageous to the steel men. Starting with small holdings, Mr. Frick gradually increased his territory and the number of his ovens until he obtained a practical monopoly of the Connellsville production and was able to dictate terms to consumers. He further strengthened his grip on the trade by investing heavily in coal lands and thus acquiring an unlimited source of supply for his ovens. Mr. Carnegie perceived the rich possibilities of a union between the steel and coke industries, and, in 1882, bought a half interest in the Frick Coke Company for $1,500,000. Six years later, on the death of one of his partners, he induced the coke king to enter the Carnegie Company, and the interests thus combined have since been, to all intents and purposes, a unit.
