G. C. (George Charles) Selden

G. C. Selden, identified in library and catalog records as George Charles Selden and born in 1870, wrote about investing and speculation in the early 1900s. His best-known work, Psychology of the Stock Market (1912), looks at how emotion, habit, and mass behavior can drive market swings as much as hard numbers do.

He also wrote The Machinery of Wall Street (1917) and Investing for Profit (1919). Records for these books show that he was closely connected with financial publishing in New York, including Ticker Publishing Company and The Magazine of Wall Street.

Much of the surviving information about Selden comes through his books and library catalogs rather than detailed biographical profiles. Even so, his work helped bring a more behavioral, reader-friendly way of thinking about markets to a broad audience long before modern finance made those ideas familiar.
