Lon Chaney

Leonidas Frank "Lon" Chaney (April 1, 1883 – August 26, 1930) was an American actor and makeup artist. He is regarded as one of the most versatile and powerful actors of cinema, renowned for his characterizations of tortured, often grotesque and afflicted, characters and for his groundbreaking artistry with makeup. Chaney was known for his starring roles in such silent horror films as The Hunchback of Notre Dame (1923) and The Phantom of the Opera (1925).

His ability to transform himself using makeup techniques that he developed earned him the nickname "The Man of a Thousand Faces". Description above from the Wikipedia article Lon Chaney, licensed under CC-BY-SA, full list of contributors on Wikipedia.
