Joseph Cawthorn was an American stage and film comic actor.
Cawthorn started out in show business as a child, debuting at Robinson's Music Hall in his hometown of New York in 1872. He appeared in minstrel shows and vaudeville as a \"Dutch\" comic, employing a thick German dialect. He later worked in British music halls and American touring companies.
Cawthorn made his Broadway debut in 1895, 1897 or 1898, and embarked on a long career lasting over two decades. His first success was playing Boris in Victor Herbert's 1898 operetta The Fortune Teller. Other notable Broadway roles included the title character in Mother Goose and inventor Dr. Pill in the fantasy musical Little Nemo. In the latter, he was called upon to ad lib to buy time during one performance. As \"the scene called for him to describe imaginary animals he had hunted\", he invented the \"whiffenpoof\" on the spot. Yale students in the audience appropriated it for the name of their glee club.
When his Broadway stardom waned, Cawthorn moved to Hollywood in 1927 and started a second prolific career, appearing in over 50 films, the last in 1942.
