Where in North America was the guillotine first and last used?

Saint Pierre

The only time the guillotine was ever used in North America was in Saint-Pierre in the late 1800s. Joseph Néel was convicted of killing Mr. Coupard on Île aux chiens on December 30, 1888, and executed by guillotine on August 24, 1889. The guillotine had to be shipped from Martinique and it did not arrive in working order. It was very difficult to get anyone to perform the execution; finally a recent immigrant was coaxed into doing the job. This event was the inspiration for the film The Widow of Saint-Pierre (La Veuve de Saint-Pierre) released in 2000. The guillotine is now in a museum in Saint-Pierre.

Excellant response Star_Gazer..
St. Pierre & Miquelon are two very small French owned islands just 15 miles South of Newfoundland..Being a French controlled area the official method of execution is or was by guillotine..Apparently the guillotine that was used back then is now on display in a museum on St. Pierre.

Out of curiosity - how come the French were allowed to keep those two when we pinched the rest of Canada off them?

Good question Baloo..It is an odd situation for sure. The islands were tossed around betwen Britian and France quite a lot for years on end.. Originally the area was very popular for it's rich fishing grounds and Basque fishermen were active there ..then the French arrived & settled them for years.. Britan took them over due to the American Revloution when the French sided with the Americans..Then they were returned to France due to the Treaty of Paris in the early 1800's...messy stuff. Interesting situation during WW2 when the governor of the Islands declared he was siding with the Vichy French..Threats from Britan and Canada were made to invade.. Charles DeGaulle then ordered a mini invasion and had the governor arresed and installed a Free French regime..The town square of St. Pierre is now known as Place Charles DeGaulle in honor of that mini invasion...
