Thomas Dewey messed up ALL public education, so American History would be swept up in that.
Oliver Wendell Holmes messed up pretty much ALL of the law schools.
Thomas Dewey was “the little man on the wedding cake” who lost to FDR in 1944 and to Truman in 1948. If Dewey had won in 1948, Earl Warren would have become Vice President. If Dewey had then been re-elected in 1952, we wouldn’t have had a Warren Court.
John Dewey was the philosopher and promoter of “progressive” education. Thomas Dewey was the New York governor and presidential hopeful.
