Frans Michel Penning (12 September 1894, Gorinchem – 6 December 1953, Utrecht) was a Dutch physicist. The Penning trap, used for storing charged particles, as well as the Penning mixture and Penning effect of gas discharge tubes are named after him. He also invented a type of cold cathode vacuum gauge known as Penning gauge.
