Humphry Davy was an even greater success, as was his assistant and successor Michael Faraday. Davy's immediate successor was William Thomas Brande. Thus the Institution has had an instrumental role in the advancement of science since its founding. Notable scientists who have worked there include Sir Humphry Davy (who discovered sodium and potassium), Michael Faraday, James Dewar, Sir William Henry Bragg and Sir William Lawrence Bragg (who jointly won the Nobel prize for their work on x-ray diffraction), Max
Edmund Davy 1790 - 24 Jan 1868) also was a chemist who spent some time (1808–1811) assisting Humphry in his chemistry research at the Royal Institution. John was the first to prepare and name phosgene gas. Edmund William Davy (born in 1826), son of Edmund Davy, became professor of medicine in the Royal College, Dublin, in 1870. That they cooperated in research is shown in a notice to the Royal Irish Academy on the manufacture of sulphuric acid which Edmund Davy ends with an acknowledgement of the assistance he received in his experiments given by his son, Edmund William Davy.
