The toaster was invented before World War I, which lasted from 1914 to 1918. An electric toaster was invented in 1893, but it was not commercially successful. A successful electric toaster was invented in 1909, also before WWI. But the pop-up toaster was not invented until after WWI, in 1921. So it is likely that refinements of the toaster invention were continuing during the war.
