Von Drais called his device a Laufmaschine or running machine, but others called it a velocipede or a dandyhorse. Curiously, we owe thanks for the invention to a volcano - Mount Tambora in Indonesia. When Tambora erupted in 1815, following a series of smaller eruptions, it ejected so much dust into the atmosphere that global temperatures dropped by an average of as much as 0.7C and harvests failed throughout the Northern Hemisphere in what became known as The Year Without A Summer; he had aimed to invent a machine that would be able to replace horses both as personal transport and as a way to transport food around the country. In 1848, Drais publicly renounced his nobility, stating that he wished to be known as Citizen Karl Drais in support of the French Revolution. The Prussian government viciously suppressed a revolution of their own the following year and, viewing Drais as an enemy of the establishment, seized his pension and belongings to assist in covering the costs of preventing unrest. He died destitute two years later.
Happy birthday to David Zabriskie, cyclist with Garmin-Cervélo and the first vegan in the Tour de France (well, almost - he revealed that he would eat small amounts of salmon during the 2011 Tour). Zabriskie is known for his eccentric sense of humour and unconventional ways, frequently interviewing other riders in the peloton and later posting the results on his website. He also collects Marvel action figures, his collection being stolen along with thousands of dollars of cycling equipment and Olympic memorabilia from his home in 2009 when he and wife Randi Reich were away at the Tour of California.
Zabriskie won a stage in the Tour de France in 2005, beating Lance Armstrong and becoming the first American to have won stages in all three of the Grand Tours. David's career has been held back by misfortune with several crashes ending his races early - the most recent was Stage 9 in the 2011 Tour when he injured his wrist in the crash on a descent that also put Jurgen van den Broeck, Frederik Willems and Alexander Vinokourov (Vino announced his retirement afterwards but has since returned) out of the race. However (or perhaps as a result of this) he is a favourite among fans and journalists. As might be expected, he has a range of nicknames: The Green Hornet, DZ, DZNuts, Dizzy, Captain America and Zup.
