Peggy Olson is a Junior Copywriter at the Sterling Cooper advertising agency. A bridge-and-tunnel girl from Bay Ridge, Brooklyn, she attended Miss Deaver’s Secretarial School, and now shares an apartment with a roommate. Peggy started out at the firm as Don Draper’s secretary but earned a promotion by impressing Don and others with her copy for two accounts: Belle Jolie and the Rejuvenator. She spent the night with Pete Campbell shortly before his wedding; the two rekindled the affair in the office shortly after his marriage. Later, Peggy – who didn’t realize she was pregnant – gave birth to a baby boy.
