The Ivy Lee method dates back to 1918, when Lee, a productivity consultant, was hired by Charles M. Schwab, the president of the Bethlehem Steel Corporation, to improve his company's efficiency. As the story goes, Lee offered his method to Schwab for free, and after three months, Schwab was so pleased with the results he wrote Lee a check for $25,000 — the equivalent of about $400,000 today.
