Jan Janssen, Dutch cyclist
Johannes Adrianus "Jan" Janssen (pronounced [jɑn jɑnsɛn]; born 19 May 1940) is a Dutch former professional cyclist (1962–1972). He was world champion and winner of the Tour de France and the Vuelta a España, the first Dutch rider to win either. He rode the Tour de France eight times and finished all but the first time. He won seven stages and wore the yellow jersey for two days (after stage 16 in 1966 and after stage 22B in 1968). He was easily spotted in the peloton because of his blond hair and his glasses.
