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 Professor of Physics would cost £6,300. The then chancellor of the university, William Cavendish met that cost privately 18 months later, and named the department in honor of his relative, the 18th century natural philosopher Henry Cavendish. The first Cavendish Professor was the then relatively obscure James Clerk Maxwell, who had yet to complete the work that would make him the most renowned physicist of the nineteenth century. His appointment was announced on 8 March 1871, and despite initial disappointment at his being offered the place, his inaugural lecture was looked forward to by his likely students as well as his future colleagues.
