Olive Oyl is a cartoon character created by Elzie Crisler Segar in 1919 for his comic strip Thimble Theater. Thimble Theater later became Popeye after the sailor character became the most popular member of the comic strip’s cast. Olive Oyl was a character in the strip for 10 years before the first appearance of Popeye in 1929.

In the strip as written by Segar, Olive was something of a coy flapper whose extremely thin build lent itself well to the fashions of the time; her long black hair was usually rolled in a neat bun, like her mother’s. She was the more-or-less fiancée of Harold Hamgravy, a “lounge lizard” or slacker type who did as little work as possible and was always borrowing money. His attraction to other women—particularly if they were rich—naturally incensed Olive, and she once succumbed to a fit of “lunaphobia” (a kind of angry madness) over one of his amours. (When she recovered, she continued to pretend to have the disorder to win him back.) She was not immune to flattery from other men, but remained committed to Ham until Popeye’s appearance. The two did not fall in love at once (her first words to him were “Aw, shut up, you bilge rat!”), but instead fought bitterly (and hilariously) for weeks, before realizing they cared for one another.
