Andrew Jackson is Professor of Earth and Planetary Magnetism at D-EAPS. His instrumental work in the field of geomagnetism led to the creation of a model which has been used by "virtually every study of the historical magnetic field of the last 20 years". In receiving the Society's highest honour - which dates back 200 years - he joins the likes of Stephen Hawking, Jocelyn Bell Burnell, Albert Einstein and Edwin Hubble.
