Born in 1903, Paul Arzens studied at Paris Fine Arts school. He built this car (L'Oeuf -- "the egg") in Paris in 1942 -- the world's first true bubble car. The vehicle was constructed from hand-formed aluminium and a windscreen and curved side doors made of Plexiglass. (Plexiglass at the time was a new material.) Initially the L'Oeuf was electric and power came from five 12 volt 250amp batteries that powered an electric motor on the single rear wheel. After the second World War this was replaced with a 125cc engine. The vehicle was used by Arzens up until his death aged 87 in 1990; it is now in the Transportation museum in Mulhouse, France.
