William Lewis Sachtleben (died in Fort Lauderdale, Florida on December 13, 1953) was a nineteenth-century American journalist and lecturer who was one of the early globe-circling bicyclists, at one time holding a world record for long-distance bicycling. He was a graduate of Washington University His attempt in 1895 to rescue, recover, or achieve justice for fellow cyclist Frank Lenz, who had disappeared in Turkey at the time of the massacres of Armenians, was seen as akin to the earlier search for David Livingstone in Africa. He later went exploring for fortune, and entered the business world.
