The Institute of Education is the UK's premier institution for the education and training of teachers and for the conduct of educational research. Founded in 1902 as the London Day Training College, it became the Institute of Education in 1932 and is now an independent college and school of the University of London, serving some 6,600 students. It is the only college of the University of London dedicated entirely to education and related areas of social science. The Newsam Library, which holds extensive collections of current and historical materials on education and related areas of social science, was added in 1992. The Institute has been particularly fortunate in its Principals and Directors, many of whose names have passed into educational history. Some are represented in the portraits held in the Newsam Library. Sir Percy Nunn was the author of the highly influential 'Education, Its Data and First Principles', first published in 1920, whilst Fred Clarke was the inspirational educationalist during the Second World War and immediate post-war years.
