Peter Bernstein

Just saw a news article that Peter Bernstein, an economic consultant and historian, a guru in risk management and modern investment theory, dies on 5 June 2009, at the age of 90.

Peter Bernstein Inc.

He is a proponent of Efficient Market Hypothesis (EMH). Though EMH is controversial among investors, it's still an important concept in investment.
He has written many books (refer to Peter’s Book from the website above). Many of his books are "bridges" between academic theory and methods in investment industry; good reads to understand history of risk management and modern investment theory.

Among these books, many are classics, for examples:

• Capital Ideas: The Improbable Origins of Modern Wall Street
  (This book traces the historical development of modern investment and finance theory.. A list of who-is-who in modern investment theory, for e.g..Harry Markowitz, William Sharpe, Fischer Black, Myron Scholes, Robert Merton, Franco Modigliani, Merton Miller and a lot more..)
• Against the Gods: The Remarkable Story of Risk
  (This book traces the historical development of risk and risk management.)
• The Power of Gold: The Story of an Obsession
  (This book is on obsession of gold.)
