British-born David Ogilvy was one of the original, and greatest, “ad men.” In 1948, he started what would eventually be known as Ogilvy & Mather, the Manhattan-based advertising agency that has since been responsible for some of the world’s most iconic ad campaigns, and in 1963 he even wrote Confessions of an Advertising Man, the best-selling book that is still to this day considered essential reading for all who enter the industry. Time magazine called him “the most sought-after wizard in today’s advertising industry” in the early-’60s; his name, and that of his agency, have been mentioned more than once in Mad Men for good reason.
