Churchill, Rutherford and Fleming

The 20th century1901 to 1945

Winston Churchill led Britain through the Second World War, and by then he had already spent decades in politics: he first became a Conservative MP in 1900, long before the country turned to him as its wartime leader. Despite guiding Britain to victory, he lost power almost immediately afterward, losing the General Election in 1945 just as the fighting in Europe ended.

A team led by Ernest Rutherford, working first in Manchester and later in Cambridge, had been the first to split the atom, laying groundwork that fed into the research behind the atomic bomb. In 1945, Alexander Fleming was awarded the Nobel Prize in Medicine for his discovery of penicillin, a drug that was by then in mass production.
