Vincent van Gogh is seen as one of the greatest painters ever, however he was not recognized at his time having sold only one painting during his life.
He is known for cutting of his ear and drinking too much. In his last years he was suffering of painful anxiety and mental illness, and committed suicide.
He made beautiful paintings like The Potato Eaters, The Starry Night and the Sunflowers and is for sure the greatest artist of the 19th century.
