The Electromatic was the successor to the Remington Electric of 1925. The Remington was a sell-out but the timing was very bad as the company was undergoing a leadership restructuring and could not get itself together enough to extend and expand its relationship with the North East Electric Company, which manufactured the motor and power-roller base of the Remington Electric and wanted a contract before undertaking further production. So, N.E. Electric struck out on its own and came up with the Electromatic. Later, General Motors acquired control and spun off Electromatic Typewriters, Inc. In 1933, IBM acquired the assets of Electromatic, and the rest is history.
When this machine hit the desktop in '46, a lot of history was being made: The U.N. Security Council heard its first complaint, President Truman created the Central Intelligence Agency, and Winston Churchill coined the expression "iron curtain". Continuing a centuries long hunger for independence from outsiders, Ho Chi Minh was in France trying to negotiate independence, but the French high commissioner for Indochina instead declared that southern Vietnam would have a French-controlled government and war between the independence forces, the Viet Minh intensifies. The French expect to take care of the Viet Minh in eight days or so. When I went to Vietnam in 1964 this would have been news to me.
