Highwayman Nicolas J. Pelletier becomes the first person executed by guillotine.

Nicolas Jacques Pelletier (c. 1756 25 April 1792) was a French highwayman who was the first person to be executed by guillotine.

A highwayman was a robber who stole from travellers. This type of thief usually travelled and robbed by horse as compared to a footpad who travelled and robbed on foot; mounted highwaymen were widely considered to be socially superior to footpads. Such criminals operated until the mid or late 19th century. Highwaywomen, such as Katherine Ferrers, were said to also exist, often dressing as men, especially in fiction.

The first attestation of the word highwayman is from 1617. Euphemisms such as "knights of the road" and "gentlemen of the road" were sometimes used by people interested in romanticizing (with a Robin Hood–esque slant) what was often an especially violent form of stealing. In the 19th-century American West, highwaymen were sometimes known as road agents. In Australia, they were known as bushrangers.
