James Holman (1786 - 1857)

James Holman FRS (15 October 1786 – 29 July 1857), known as the "Blind Traveler," was a British adventurer, author and social observer, best known for his writings on his extensive travels. Completely blind and suffering from debilitating pain and limited mobility, he undertook a series of solo journeys that were unprecedented both in their extent of geography and method of "human echolocation". In 1866, the journalist William Jerdan wrote that "From Marco Polo to Mungo Park, no three of the most famous travelers, grouped together, would exceed the extent and variety of countries traversed by our blind countryman." In 1832, Holman became the first blind person to circumnavigate the globe. He continued traveling, and by October 1846 had visited every inhabited continent.-Wikipedia
