Jonathan Williams was Cicerone's publisher and managing director for nearly 25 years, working with authors and leading the development of the range. In his new life as an author, he, together with Lesley Williams, have made the Swiss and French Alps their special subject and explored treks and walks throughout the mountains. Based in the Lake District and the Yorkshire Dales, they enjoy spending days in the hills and months in the mountains, and have written or updated several Cicerone guidebooks for Switzerland.
