Andrew Lyne has been at the forefront of pulsar research for over 50 years. He has discovered over two-thirds of the known pulsars, has more than 400 publications to his name and has several awards including the Herschel Medal of the Royal Astronomical Society and the Descartes Prize of the European Union. He is a Fellow of the Royal Society and was Director of Jodrell Bank Observatory (1997–2007). Francis Graham-Smith was Astronomer Royal (1982–1990), Physical Secretary of the Royal Society (1988–94), Director of the Royal Greenwich Observatory (1976–81) and Director of Jodrell Bank Observatory (1981–88). He is the senior author of textbooks on optics and radio astronomy. The fifth edition of Pulsar Astronomy is the product of over 50 years of close collaboration in research at Jodrell Bank Observatory. Ben Stappers is a Professor of Astrophysics at the University of Manchester. He has been at the forefront of many aspects of pulsar astronomy from how they emit through to their use as gravitational wave detectors. He has been involved with the development and commissioning of pulsar instrumentation for telescopes including LOFAR, WSRT, Lovell, MeerKAT and the SKA. He currently holds a European Research Council Advanced grant for searching for pulsars and fast transients.
