Philip Sheldon Foner was an American labor historian and teacher. Foner was a prolific author and editor of more than 100 books. He is considered a pioneer in his extensive works on the role of radicals, Black Americans, and women in American labor and political history, which were generally neglected in mainstream academia at the time. A Marxist thinker, he influenced more than a generation of scholars, inspiring some of the work published by younger academics from the 1970s on. In 1941, Foner became a public figure as one among 26 persons fired from teaching and staff positions at City College of New York for political views, following an investigation of communist influence in education by a state legislative committee, known as the Rapp-Coudert Committee.

<span class="mw-page-title-main">Post-war</span> Period shortly after a war, usually WWII

A post-war or postwar period is the interval immediately following the end of a war. The term usually refers to a varying period of time after World War II, which ended in 1945. A post-war period can become an interwar period or interbellum, when a war between the same parties resumes at a later date. By contrast, a post-war period marks the cessation of armed conflict entirely.

<span class="mw-page-title-main">Soviet Union–United States relations</span> Bilateral relations

Relations between the Soviet Union and the United States were fully established in 1933 as the succeeding bilateral ties to those between the Russian Empire and the United States, which lasted from 1776 until 1917; they were also the predecessor to the current bilateral ties between the Russian Federation and the United States that began in 1992 after the end of the Cold War. The relationship between the Soviet Union and the United States was largely defined by mistrust and tense hostility. The invasion of the Soviet Union by Germany as well as the attack on the U.S. Pacific Fleet at Pearl Harbor by Imperial Japan marked the Soviet and American entries into World War II on the side of the Allies in June and December 1941, respectively. As the Soviet–American alliance against the Axis came to an end following the Allied victory in 1945, the first signs of post-war mistrust and hostility began to immediately appear between the two countries, as the Soviet Union militarily occupied Eastern European countries and turned them into satellite states, forming the Eastern Bloc. These bilateral tensions escalated into the Cold War, a decades-long period of tense hostile relations with short phases of détente that ended after the collapse of the Soviet Union and emergence of the present-day Russian Federation at the end of 1991.

The 1911–1917 era lists divisions raised during the Army's first attempts at modernizing the division, prior to the authorization of permanent divisions, and the 1917–1941 era lists the first permanent divisions, prior to advent of specialized divisions. The 1941–present era lists all of the divisions organized, raised, or authorized since then.

<span class="mw-page-title-main">Military aircraft insignia</span> Markings applied to aircraft for visual identification

Military aircraft insignia are insignia applied to military aircraft to visually identify the nation or branch of military service to which the aircraft belong. Many insignia are in the form of a circular roundel or modified roundel; other shapes such as stars, crosses, squares, or triangles are also used. Insignia are often displayed on the sides of the fuselage, the upper and lower surfaces of the wings, as well as on the fin or rudder of an aircraft, although considerable variation can be found amongst different air arms and within specific air arms over time.

The role that women have played in wartime throughout History is something that cannot be understated because it was impactful and influential. California, during World War II, and the role that women played in upholding the defense industry specifically, is a prime example of just how important women were to the war effort. The airframe industry in California was one that saw dramatic growth in a very short period of time as World War II began. When the United States officially became involved, many men who were working in the airframe plants left to join the services and serve their country overseas. This caused a major labor shortage in the airframe industry that was needed to produce planes at a higher rate than ever before. At first, many of the manufacturers of aircraft were reluctant to hire women but eventually had to because the demand was high for America to keep up with demand. Donald Douglas was the founder of the Douglas Aircraft Company which was a major producer of aircraft during World War II. Donald Douglas stated “Men are more stable and efficient. Without women, no distractions are present in the canteen or the shop floor.” However, this resentment towards women in the workplace changed drastically as the war raged on. According to the California Labor Review, California airframe industries began to hire women to fill in the labor shortages. In 1942, there were fewer than 10,000 women working in the California airframe industry but less than a year later in 1943, that number jumped to over 120,000. Women were essential to the war effort on the home front in many ways but the airframe industry in California is just a small example. After the war, however, many women lost their airframe jobs in the defense industry because the factories returned the job to the men coming home from war. Housewives were a large number of workers who withdrew from the workforce as a result of the war ending. No matter how history frames the influence that women had in World War II on the homefront, the role that women played in the war effort was essential to the United States and its victory in the war.
