(http://en.wikipedia.org/wiki/Highwayman)   Nicolas J. Pelletier became the first person executed by guillotine.  
Antoine Louis, member of Académie Chirurgical, took the first practical steps 
 towards the creation of the guillotine. It was from his design that the 
first  guillotine was built. The guillotine was first called "Louison" or 
"Louisette",  but the press preferred Guillotine as it had a nicer ring to it. Antoine 
Louis  was born in Metz 1723, and he died in Paris in  1792.
