Henry Louis Mencken was an American journalist, satirist, cultural critic and scholar of American English. Known as the "Sage of Baltimore", he is regarded as one of the most influential American writers and prose stylists of the first half of the twentieth century. He commented widely on the social scene, literature, music, prominent politicians and contemporary movements. His satirical reporting on the Scopes trial, which he dubbed the "Monkey Trial", also gained him attention.
As a scholar, Mencken is known for The American Language, a multi-volume study of how the English language is spoken in the United States. As an admirer of the German philosopher Friedrich Nietzsche, he was a detractor of religion, populism and representative democracy, which he believed to be a system in which inferior men dominated their superiors. Mencken was a supporter of scientific progress, skeptical of economic theories and critical of osteopathic and chiropractic medicine.
Mencken opposed American entry into World War I and World War II. His diary indicates that he was a racist and anti-semite, and privately used coarse language and slurs to describe various ethnic and racial groups . Mencken also at times seemed to show a genuine enthusiasm for militarism, though never in its American form. "War is a good thing," he once wrote, "because it is honest, it admits the central fact of human nature… A nation too long at peace becomes a sort of gigantic old maid."
Mencken's longtime home in the Union Square neighborhood of West Baltimore was turned into a city museum, the H. L. Mencken House. His papers were distributed among various city and university libraries, with the largest collection held in the Mencken Room at the central branch of Baltimore's Enoch Pratt Free Library.
