It’s Italian artist Amedeo Modigliani today. He was born in Italy in 1884 and died in 1920. Modigliani led a typical bohemian lifestyle, but with more excesses than most. He was marked for an early death by contracting TB whilst young.
Modigliani’s style is his own though. He is not easily classified, though he is often called an Expressionist. He was influenced by Toulouse Lautrec, Cezanne: his sculpture owes much to the influence of Brancusi. Although he did paint a few landscapes, he became famous for his portraits and nudes.
