The Baron of Wall Street: Clarence Dillon and the Making of the Modern Financial World – The Definitive Business Biography of Stock Market Economics and Investment History

by William R. Loomis Jr.

The definitive biography of one of the most influential and innovative figures in the history of American finance who revolutionized Wall Street and whose story reads like a real-life Great Gatsby

J.P. Morgan. John D. Rockefeller. Charles E. Mitchell. These are some of the most prominent icons of wealth and influence during the Roaring Twenties. Yet the one figure who has strangely escaped notice all these years is an enigmatic banker by the name of Clarence Dillon. In the dazzling 1920s, as he rose in wealth and influence, Dillon became one of the original behind-the-scenes players in Hollywood, and his contact list included everyone from Thomas Edison to Charlie Chaplin and Joseph P. Kennedy to FDR.

Like many great figures in history, Dillon’s personality was complex and contradictory: he could be utterly ruthless and cold-blooded, yet he was also sophisticated and elegant. This immensely influential man left a lasting mark on the history of finance in America. Yet, strangely, he eluded the close attention of biographers and historians—until now.

A revolutionary in finance, Clarence Dillon single-handedly:
Created modern bankruptcy law
Pioneered leveraged buyouts
Invented junk bonds
Engineered some of the biggest mergers and acquisitions ever seen

This first-ever complete inside look at Dillon and his life will fill a void in how we view the wild excesses of the Roaring Twenties, and how we understand the increasingly complex nexus between Wall Street and political power in our own time. The Baron of Wall Street is a vivid, novelistic account of Wall Street’s most formative years and its transformation through one dynamic and influential player in the financial world, highlighting his significant role in shaping US foreign policy today.

This book is not merely a biography but also a chronicle of the origins of financial engineering. It details how Dillon single-handedly pioneered the rudiments of leveraged buyouts (LBOs) and junk bonds, while also driving the establishment of modern bankruptcy law.

Cold blue blood
ritch by wind and black flower
wilth te be one
and have many window
no door can be open to any stuped any more
just pass
to cold blue blood world
and snaks words
and nasty dream and paper
and be one
with one sound and ear
just in news paper street
shadow of stone
and pic of old man same

Well done, readable biographer of apparently one of the most underrated financiers of the pre-Depression/Gilded age. Chapters offer simple snapshots of Clarence Dillon and the Dillon Read Co. through the Depression on the anarchy and graft of unregulated modern American banking. Cool stuff @salvo would like

[Gerald Krug]

A worthy book of a towering figure back at the turn of the 1900s and into the Great Depression. Recommended for all interested in the general history of the United States during that time and especially in the study of how one person can influence events and history.

Very interesting book. It's a good explanation of why the SEC exists today.
