in the role of women in society as a whole. When the male breadwinner returned, wives could stop working. Alice Throckmorton McLean founded the American Women's Voluntary Services (AWVS) in January 1940, 23 months before the United States entered the war. When Pearl Harbor was bombed, the AWVS had more than 18,000 members who were ready to drive ambulances, fight fires, lead evacuations, operate mobile kitchens, deliver first aid, and perform other emergency services. By war's end the AWVS counted 325,000 women at work and selling an estimated $1 billion in war bonds and stamps. At the end of the war, most of the munitions-making jobs ended. Many factories were closed; others retooled for civilian production. In some jobs, women were replaced by returning veterans who did not lose seniority because they were in service. However, the number of women at work in 1946 was 87% of the number in 1944, leaving 13% who lost or quit their jobs. Many women working in machinery factories and more were taken out of the workforce. Many of these former factory workers found other work at kitchens, being teachers, etc. The table shows the development of the United States labor force by sex during the war years. Women also took on new roles in sport and entertainment, which opened to them as more and more men were drafted. The All-American Girls Professional Baseball League was the creation of Chicago Cubs owner Philip Wrigley, who sought alternative ways to expand his baseball franchise as top male players left for military service. In 1943, he created an eight-team league in small industrial cities around the Great Lakes. Night games offered affordable, patriotic entertainment to working Americans who had flocked to wartime jobs in the Midwest hubs of Chicago and Detroit. The league provided a novel entertainment of women playing baseball well while wearing short, feminine uniform skirts. Players as young as fifteen were recruited from white farm families and urban industrial teams. Fans supported the League to the extent that it continued well past the conclusion of the war, lasting through 1953. Farming Labor shortages were felt in agriculture, even though most farmers were given an exemption and few were drafted. Large numbers volunteered or moved to cities for factory jobs. At the same time, many agricultural commodities were in greater demand by the military and for the civilian populations of Allies. Production was encouraged
