Final answer:
Norman Rockwell popularized the image of 'Rosie the Riveter,' an icon representing the essential role of women in the workforce during World War II and symbolizing female empowerment and patriotism.
Step-by-step explanation:
During the Second World War, Norman Rockwell contributed significantly to the American war effort by creating an iconic image that has since become synonymous with female empowerment and the contribution of women to the workforce. This image was none other than Rosie the Riveter, which not only reflected the spirit of determination among American women but also served as a piece of propaganda to encourage more women to join the industrial labor force. Rockwell's depiction of Rosie was tough yet feminine, balancing the need for additional workers with the societal expectations of women at the time. His work helped popularize the character and supported the idea that women were indispensable to the war effort, embodying the message that 'We Can Do It!' and thus playing a crucial role in shifting public perception and policy.
