Swiss researcher developed magnet to remove foreign bodies
Magnets have led travelers and explorers safely home and have spared ship's captains from the ocean depths. Today, they play a major role in medicine in the analysis of ourinternal organs by the use of magnetic resonance imaging (MRI).
Ophthalmology also had its era of the use of magnets.
Julius Hirschberg (1843-1925), ophthalmology's great historian and also a disciple of von Graefe, also made important contributions to ophthalmology and was the first person to use an electromagnet for removing foreign bodies in 1879.
