Adolf Dietrich (November 9, 1877 - June 4, 1957) was one of the most renowned Naïve artists and Swiss painters of the 20th century.
Adolf Dietrich was born to poor farmers in the canton of Thurgau as the youngest of 7 children.
Upon discovering his exceptional graphical talents, his schoolteacher suggested that he become a lithographer.
His parents, however, refused since he was needed as a farmhand.
