[7] The Duke of Devonshire had given to Maxwell, as head of the laboratory, the manuscripts of Henry Cavendish's unpublished Electrical Works.

Under his leadership the neutron was discovered by James Chadwick in 1932, and in the same year the first experiment to split the nucleus in a fully controlled manner was performed by students working under his direction; John Cockcroft and Ernest Walton.

The news reached readers of The New York Times the next day; Victor K. McElheny, in researching his biography, Watson and DNA: Making a Scientific Revolution, found a clipping of a six-paragraph New York Times article written from London and dated 16 May 1953 with the headline "Form of `Life Unit' in Cell Is Scanned."

Bragg's original announcement of the discovery at a Solvay Conference on proteins in Belgium on 8 April 1953 went unreported by the British press.

Sydney Brenner, Jack Dunitz, Dorothy Hodgkin, Leslie Orgel, and Beryl M. Oughton, were some of the first people in April 1953 to see the model of the structure of DNA, constructed by Crick and Watson; at the time they were working at the University of Oxford's Chemistry Department.

According to the late Dr. Beryl Oughton, later Rimmer, they all travelled together in two cars once Dorothy Hodgkin announced to them that they were off to Cambridge to see the model of the structure of DNA.

[14] The Cavendish Professors were the heads of the department until the tenure of Sir Brian Pippard, during which period the roles separated.

[22] As of 2015[update] senior academic staff (professors or readers) include:[34] The Cavendish is home to a number of emeritus scientists, pursuing their research interests in the laboratory after their formal retirement.
