In the spring of 1892, Frank G. Lenz, a gallant young accountant and expert amateur photographer from a modest German-American family, set forth from his unhappy home in Pittsburgh to circle the globe atop a new ‘safety’ bicycle with inflatable tyres (essentially the modern machine). He brought along a large wooden camera, which used newly introduced film, and arranged to send regular reports to his sponsor, Outing magazine, effectively making him a harbinger of the great bicycle boom that was about to explode with stunning social and industrial repercussions. Two years, fourteen thousand miles and many adventures later, after crossing the United States, Japan, China, Burma, India and Persia, just as he was about to enter Europe for the home stretch, Lenz vanished. His presumed murder in Asiatic Turkey jolted the American public and drew international attention. Including many rare photos, The Lost Cyclist recounts the short but remarkable life of Lenz and the heroic efforts of another American ‘globe girdler’, William L. Sachtleben, who was sent by Outing to unravel Lenz’s mysterious death.
