Drawing extensively on letters sent to me by him over fifty years, this paper tries to present a vivid picture of Paul Hirst in different aspects of his life. The first section covers the huge amount of work he did at the universities of London and Cambridge—in teaching and writing philosophy of education, high-level administrative university responsibilities, and involvement in national education policy. This is followed by a glimpse into his passion for music, especially opera. Final sections show him as (...) an academic mentor and friend. (shrink)
