The 1816 Year Without a Summer, the Tambora eruption and a theory about the bicycle
Eighteen Hundred and Froze to Death, or The Year Without a Summer: such is the name under which 1816 entered history, when snow fell every month in Western Europe and parts of the USA, temperatures stayed at winter levels, and rain and hail never ceased. A century later, climatologists explained the phenomenon by the largest volcanic eruption in recorded history, that of Mount Tambora in Indonesia. Some hold that the weather of 1810-1819, the coldest decade in 500 years, may even have prompted the invention of the bicycle, owing to a shortfall in the production of oats, the staple of the horse's diet.
