Prof. Leon Mestel has been an inspiration to many to study the role of magnetism in the Cosmos. To mark the occasion of his retin'ment from the University of Sussex after 43 years in astrophysics, several of his friends and former students decided to hold an advanced research workshop in his honour. NATO agreed to finance this venture which was held at the Institute of Astronomy at Cambridge. The scientific organizing committee was J. Landstreet, D. Lynden-Bell, F. Pacini, M.A. Rud0rman and N.O. Weiss and most leading experts on Cosmical magnetism agreed to come. We are particularly grateful to Lyman Spitzer who, ably helped by his wife Doreen, !!;ave the after dinner addre~s on how the goddess Astrophysica had foreseen Leon's achievements in classical Greek times. Not without regret we decided to maintain the homog0neity of the material and therefore could not cover Leon Mestel's major achievements in non-magnetic astronomy. His work on the cooling of white dwarfs, his understanding that degenerate hydrogen was a nuclear explosive since its pressure was almost independent of temperature and hence, his picture of supernovae, which is now more commonly applied to novae, his seminal understanding of the 'law' of galactic rotation and his work on the non-linear development of t hp anisotropies generated in gravitational collapse.

With new observations delineating the large-scale magnetic fields in galaxies and renewed interest in the influence of magnetic fields on star formation and on the collimation of jets this book provides a timely review of cosmic magnetohydrodynamics. The book has a broad sweep, from the theory of the Earth's dynamo through the magnetically dominated Solar corona to the magnetic fields of stars, galaxies quasars and the intergalactic plasma. Particular strong points are the magnetic fields of degenerate stars. Both white dwarfs and the fascinating evolution of neutron stars' magnetic fields are discussed in detail. The book is dedicated to Professor Leon Mestel who has seen the subject grow from its early days to its current flowering on the wealth of new observations described here. Stellar winds, cosmic rays, galactic dynamos, active galactic nuclei and black holes provide a wide range for both scientific imagination and precise deduction. Many of the creators of the subjects have contributed to this volume, which is vital reading for astronomy graduate students with magnetic interests as well as plasma physicists.
