Gösta Adrian-Nilsson (2 April 1884 in Lund - 29 Mars 1965 in Stockholm), usually referred to as GAN, was a Swedish artist and writer. He is regarded as a pioneer of the Swedish modernist art movement.
The fact that GAN was gay was reflected in many of his works. For example, for periods he was fixated by sailors and adored masculine strength. Another favorite motif was sportsmen.
