The Department has a distinguished history, with the study of Physics at King's College dating back to its foundation in 1829. The first Professor was Sir Charles Wheatstone, with other former professors including James Clerk Maxwell, who discovered the unified equations of electromagnetism while at King's, and four Nobel laureates. The seminal x-ray crystallography work by Wilkins and Franklin which led to the discovery of the structure of DNA was performed in the Physics Department.
