Book excerpt: Rudolf Steiner spent some five months of his life in Britain, visiting there ten times between 1902 and 1924. With the exception of German-speaking countries, the longest time Steiner spent abroad was in Britain, a place he clearly considered central to his work.In this extraordinary, thorough study of more than 1,200 pages and dozens of illustrations, Crispian Villeneuve documents those important visits, reproducing letters, articles, records and other archival material, much of it published for the first time. He also studies the interconnected theme of the life and work of D.N. Dunlop, Rudolf Steiner's closest British colleague.
