Cavendish Professor of Physics However, it was poorly advertised, so it was only to his students that he laid out his plans for physics at Cambridge. When Maxwell began the actual course a few days later with a lecture on heat, it was attended by academics in formal dress, in the belief that it was the first lecture. Maxwell spent the next three years supervising the construction of the dedicated Cavendish Laboratory, and published in 1873 A Treatise on Electricity and Magnetism. Maxwell's health deteriorated a short time into his tenure, and he died in 1879, aged 48. Lord Rayleigh replaced Maxwell immediately upon
Cavendish Laboratory of Devonshire had given to Maxwell, as head of the laboratory, the manuscripts of Henry Cavendish's unpublished "Electrical Works". The editing and publishing of these was Maxwell's main scientific work while he was at the laboratory. Cavendish's work aroused Maxwell's intense admiration and he decided to call the Laboratory (formerly known as the Devonshire Laboratory) the Cavendish Laboratory and thus to commemorate both the Duke and Henry Cavendish. Physical Chemistry (originally the department of Colloid Science led by Eric Rideal) had left the old Cavendish site, subsequently locating as the Department of Physical Chemistry (under RG Norrish) in the then
