The Titans of Technical Analysis: "Charles Dow"

Charles Dow developed the Dow Theory but died in 1902 before seeing its full implications. S.A. Nelson and William Hamilton refined the theory into what it is today. Nelson wrote The ABC of Stock Speculation and was the first to use the term "Dow Theory.” Hamilton further refined the theory through a series of articles in The Wall Street Journal from 1902 to 1929 and wrote The Stock Market Barometer in 1922, explaining the theory in detail. In 1932, Robert Rhea further refined the analysis of Dow and Hamilton in his book, The Dow Theory.
