Reynolds Securities was a publicly traded brokerage firm. Founded in 1931 by Richard S. Reynolds, Jr., the firm merged with Dean Witter & Co. to form Dean Witter Reynolds Organization Inc. in 1978, which was then the biggest merger in the history of Wall Street.
The firm's tagline, "We work for a world of investors. One at a time." was adapted to "We measure success one investor at a time" and was used by Dean Witter and later Morgan Stanley.
