David John Lewis was the leading expert on social insurance legislation on the HouseWays & Means Committee. He introduced the Social Security bill into the House on January 17, 1935. However, Chairman Doughton, exercising what he took to be the Chairman's privileges, made a copy of Lewis' bill and submitted it himself. Then he persuaded the House clerk to give him a lower number than Lewis' copy. Newspapers then began calling the bill "The Wagner-Doughton bill." When Lewis found out, he sputtered and swore, then went to work to understand every sentence and master the arguments in favor of the bill. And when David Lewis walked down the aisle of the House to debate on the bill's behalf, he received a standing ovation – a subtle rebuke to Chairman Doughton's high-handed treatment.
