Amrus Natalsya was an Indonesian sculptor and painter who studied at the Indonesian Arts Academy in Yogyakarta. He was known for his unique style of sculpting and painting on wood, which challenged traditional fine art practices. He co-founded the art studio Sanggar Bumi Tarung, which was affiliated with the People's Cultural Institute (Lekra), and was arrested during the anti-communist purges of 1965-66. Natalsya's enduring convictions about art and humanism are reflected in his work, which often portrayed the struggle of the people.
