Born in the UK, and following degrees at the Univerities of Bristol and Sussex, Martin Elvis got his PhD under Prof. Ken Pounds at the University of Leicester (UK) in 1978 for work with the Ariel V satellite. Ariel V was only the 2nd satellite to be devoted to X-ray astronomy. ... His PhD thesis demonstrated that powerful X-ray emission was a normal feature of Active Galactic Nuclei (or "AGN"). AGN X-ray emission has been a lively area of research ever since. ...
