Throughout the history of cycling, there are numerous riders that came to the sport from speed skating; this is especially true in the Netherlands where speed skating is very popular and the best-known example of the phenomenon, Marianne Vos, was born - but there have been British speed skaters-turned-cyclists too.
Cyril Horn was born in Upwell, a village that sits on the border between Norfolk and Cambridgeshire, on this day in 1904. After leaving school at the age of 12 he went to work in the family smithy making horseshoes, a profitable business at the time as the Army were sending vast numbers of horses to the First World War; toughened up by the hard work, Horn became a successful skater and won numerous national championships, also skating at the 1924 Olympics. He and his brother Dennis probably took up cycling to help maintain his fitness during the summer and almost immediately became as successful in velodromes, on the grass tracks and in cyclo cross (which was another Dutch import that was very popular in the region at one time) and many fans expected them to be selected for the 1936 Olympics in Berlin; however, neither were - Cyril later revealed that they had preferred to stay at home anyway. (For an excellent history of the Horn brothers and their achievements in skating and cycling, see Classic Lightweights.)
Born in Dulwich, London on this day in 1929, John Forester moved with his family to California in 1940. He later earned a place studying physics at the state university but left with a degree in English, then joined the Navy before returning to California to become an engineer and academic. He had been a keen cyclist since early childhood; when his father, the novelist and creator of Horatio Hornblower, C.S. Forester, died leaving an unexpectedly large estate (thus revealing to the family that he had lied to them about his wealth for many years and that he had been living a secret life including a secret marriage), Forester found himself with the means to devote the rest of his life to cycling advocacy and became a renowned expert on the science of cycling.
Forester is best-known today for his books Bicycle Transportation (MIT Press ISBN 0-262-56079-8) and Effective Cycling (MIT Press ISBN 0-262-56070-4). In them, he is deeply sceptical about the benefits of many aspects of cycling infrastructure, including segregated cycle lanes. Both remain standard texts for students of many cycling safety programs; they should be read by every cyclist.
