Biographical Note for guillotine

  • Guillotin play \gē-yȯ-taⁿ\, Joseph–Ignace (1738–1814), French surgeon. Guillotin was a member of the National Assembly during the time of the French Revolution. In 1789 he proposed the passage of a law requiring that all death sentences be carried out by decapitation, a practice up to that time reserved for the nobility. At the time decapitation was perceived to be a humane method of execution, and its uniform application was intended as a statement of egalitarian ideals. Various decapitation devices had been in use for centuries, but an improvement was commissioned, and subsequently introduced in 1792. Gradually the device became known as the guillotine as it became associated with the man who had advocated it as a humane instrument of capital punishment. The surgical instrument known as the guillotine is so called because it features a similar sliding-blade action.
