World War II recruitment posters encourage men to join the service — and women to join the workforce.

Following the attack on Pearl Harbor, Minnesota is swept up in the war effort along with the rest of the country. Between 1941 and 1945, more than a quarter of a million men and women are inducted into the military through the Fort Snelling Reception Center. Shortages of male workers force Twin Cities businesses to hire women — some mothers, many recent high-school graduates — as lifeguards, streetcar conductors and telegraph operators.
