Ghulam Sediq Wardak (born 1942) is a peasant inventor in Afghanistan, credited with 341 inventions, none of which are patented. He is a local hero, despite being only semi-literate, and having no formal higher education. His inventions tend to be practical devices, inspired by needs he perceives in his daily life. His first, made when he was seventeen, was a radio powered by the wearer's bodily electricity. He has devoted himself to inventing full-time, being supported financially by his four sons.
