Query: America's Gilded Age

Ron Chernow is good at writing in great detail while making his books interesting. "House of Morgan" is well documented as are all of Chernow's books. This book is the interesting story of big banking in the United States and abroad during the period of 1850-1900. Chernow goes beyond the earlier years of the J. P. Morgan empire to the present; giving an introduction to Morgan/Chase as we know it today. The early founder, Pierpont, was ruthless, secretive and rich. The book is a long one, and took awhile to read, but it was worth the time.
