George W. Pepper (March 16, 1867 - May 24, 1961) was an American lawyer, law professor, and Republican politician from Philadelphia, Pennsylvania. He represented Pennsylvania in the United States Senate.
During 1920's controversy about the expansion of advertising, Senator Pepper argued for a "nationwide code of regulation," as pronounced in a 1929 speech to the Outdoor Advertising Association of America. He pointed out that in preserving natural beauty, no national economic benefit was lost-- real estate values and related figures would increase without the addition of billboards. Pepper represented what was, at the time, the general popular will: that if billboards became mainstream, this would signal advertising becoming too obtrusive, too aggressive in its campaign to persuade the public.
