James Nye studied Theology at Oxford, and later completed a PhD in Financial History at Kings College London. His thesis included case studies of early electric clock companies, reflecting a lifelong involvement in horology, especially in the electrical arena. From practical bench work on clocks as a teenager, his career progressed to researching and writing on the history of time measurement. A continuing theme in his ongoing work is the emergence of distributed accurate timekeeping from the late nineteenth century onwards.
