Henri Philippe Main (1856-1951) was a military hero in World War I and premier of France in 1940.
In June of that year, he called for an armistice with Germany and became the “chief of state” of the puppet government at Vichy.
After the war, he was sentenced to death, but the sentence was commuted to life imprisonment.
He died at the age of 95 in a military prison on an island off the coast of France.
