This dictionary provides the reader with an easily accessible guide to the biographies of approximately 450 educationists. It covers the period from 1800 to the present day and includes a wide range of people who were active in promoting education at different levels.

This is a tribute from historian and educationists to the work and influence of Peter Gordon, Emeritus Professor at the Institute of Education in London. The essays are grouped round the central theme of Professor Gordon's many publications - the educational history of the 19th and 20th centuries - but they also reflect the breadth of his interests and depth of scholarship within that field.

This biographical dictionary is a companion volume to Dictionary of British Educationists, also written by Peter Gordon and Richard Aldrich. It provides a guide to the lives and work of more than 500 Americans, Cana dians and Europeans who represent many of the different categories subsumed under the term educationists.

GCHQ (Government Communication Headquarters) is the successor to the famous Bletchley Park wartime code-breaking organisation and is the largest and most secretive intelligence organisation in the country. Richard Aldrich traces GCHQ's evolvement from a wartime code-breaking operation to one of the world's leading espionage organisations.
