1901-3 – Walking Lunar Vehicle (Science Fiction) – Jerzy Zulawski (Polish)

Some of these early concepts for lunar exploration had elements of practicality; others were pure whimsy. One of the first, by Polish science-fiction writer Jerzy Zulawski (1874-1915), fell into the first category. His rover design appeared as an illustration in his 1901 tale "Szrebyym Globie" ["On the Silver Globe"] and featured full pressurization, electrical power, and two forms or propulsion: large, spoked wheels that could be interchanged with leg or "claws" mounted on a triangular framework that would be used to climb up mountains or travel over rough terrain. Zulawski's invention, like Boeing's real lunar rover, had a top speed of about 10 miles per hour. He also realised, like those who would follow his footsteps, that combustion engines wouldn't work on the airless Moon, and instead, chose to power his vehicle with an electric motor, and like most later concepts of Lunar Rovers, Zulawski's was a big vehicle with an enclosed cabin. His, he said, could carry a crew of five and a year's worth of supplies.
Zulawski's story was originally a serialisation starting in 1901, later published as a book in 1903.
