Of all the men I have met—and I have now had a fairly long and active life and have met a very great variety of interesting people—one only has stirred me to a biographical effort. This one exception is F. W. Sanderson, for many years the headmaster of Oundle School. I think him beyond question the greatest man I have ever known with any degree of intimacy1, and it is in the hope of conveying to others something of my sense not merely of his importance, but of his peculiar2 genius and the rich humanity of his character, that I am setting out to write this book. He was in himself a very delightful[Pg 2] mixture of subtlety3 and simplicity4, generosity5, adventurousness6, imagination and steadfast7 purpose, and he approached the general life of our time at such an angle as to reflect the most curious and profitable lights upon it. To tell his story is to reflect upon all the main educational ideas of the last half-century, and to revise our conception of the process and purpose of the modern community in relation to education. For Sanderson had a mind like an octopus8, it seemed always to have a tentacle9 free to reach out beyond what was already held, and his tentacles10 grew and radiated farther and farther. Before his end he had come to a vision of the school as a centre for the complete reorganisation of civilised life.
