Ralph Lehman has spent twenty years managing portfolios for clients and advising them on investment, tax, estate, and financial planning issues. When he first encountered ETFs, he was intrigued by this hybrid security that was changing how people could invest in the markets. He began researching the ETF's history and noticed that no one had written a full account of their incredible story. What began as hobby of ordinary research and several curious phone calls progressed into writing a book on the story of how the first ETFs were developed.

Ralph works for a financial firm that advises defined benefit and defined contribution retirement plans on their investments. He is an avid reader and enjoys a broad range of history-American, financial, economic, ancient Greek and Roman, and early Church. Ralph and his wife Charlotte reside in Knoxville, Tennessee, along with their pet Brittany, Rocky.
