Alain Robert (born as Robert Alain Philippe on 7 August 1962) is a French rock climber and urban climber. Known as "the French Spider-Man" or "the Human Spider", Robert is famous for his free solo climbing, scaling skyscrapers using no climbing equipment except for a small bag of chalk and a pair of climbing shoes. Because authorities do not normally give him permission for such dangerous exploits, Robert will appear at dawn on the site of whichever giant skyscraper he has chosen to climb. His exploits attract crowds of onlookers who stop to watch him climb. As a consequence, Robert has been arrested many times, in various countries, by law enforcement officials waiting for him at the end of his climb. In recent years, however, Robert has done his climbs with permission and sponsorship. His rock-climbing physical training and technique allow him to climb using the small protrusions of building walls and windows (such as window ledges and frames). Many of his climbs provide him no opportunity to rest and can last several hours. He sometimes has a small bag of climbing chalk powder fastened around his waist. Robert has climbed landmarks including the Burj Khalifa, Eiffel Tower, the Sydney Opera House and the Montparnasse Tower as well as other of the world's tallest skyscrapers, most of them performed free-solo. On 20 March 1997, he climbed the Petronas Twin Towers in Kuala Lumpur, Malaysia but was arrested at the 60th floor, 28 floors below the top. On 16 April 1998, he climbed the high Luxor Obelisk in Paris. In June 1999, Robert climbed the Marriott Hotel in Warsaw. On 20 August 1999, he climbed the Sears Tower, the second man to do so after Dan Goodwin. However, Robert performed the climb with no equipment other than a chalk bag and shoes, while Goodwin used suction cups and sky hooks, wearing a homemade Spider-Man suit. On 21 February 2003, he legally climbed the National Bank of Abu Dhabi, UAE, watched by about 100,000 spectators. It became more frequent for Robert to be paid to scale buildings as part of publicity efforts.
