Heinrich Gustav Magnus (German pronunciation: [ˈhaɪnʁɪç ˈɡʊsta(ː)f ˈma(ː)ɡnʊs] ; 2 May 1802 – 4 April 1870) was a German experimental scientist. His training was mostly in chemistry but his later research was mostly in physics. He spent the great bulk of his career at the University of Berlin, where he is remembered for his laboratory teaching as much as for his original research. He did not use his first given name, and was known throughout his life as Gustav Magnus.
