Betty Crocker was born in 1921 in the Home Services Department of Minneapolis' Washburn Crosby Company, which would later become General Mills. She was conceived as a pen name to answer the torrent of baking questions pouring into the office, and the name stuck. In the decades that followed she became the domestic ideal, the role model to which millions of American women aspired, or were expected to aspire.
