Jon Lewis read English at Cambridge and then taught for three years in foreign universities before joining the British motor industry. Most of his business career was spent in continental Europe, with assignments in Belgium, Germany, France, and finally Italy where he was awarded the OBE for services to British commercial interests. Since retiring he has completed research programs and writing projects on a wide range of subjects. His interest in the Macedonian Campaign began with the discovery of his grandfather's war diary, and spread out from there. He and his wife Josée now live in France, and continue to travel widely.
