KAYSERSBERG, France — The suicide of Anthony Bourdain, the celebrity chef and television host, left the residents of Kaysersberg, a small village in the Alsace region of France, known for its wine, local food and architecture, puzzled about why he chose this place to end his life.

Mr. Bourdain’s sudden death at Le Chambard, a five-star hotel in the village, also sent shock waves through the world’s restaurant industry.

It spurred an outpouring among fans and foodies, too, who paid tribute on social media to a man who used food as a passport to understand other cultures and who used his star power to back the #MeToo movement, in which his girlfriend, Asia Argento, an Italian actress, was a central figure.

The French officials investigating the suicide said on Saturday that he had been found hanging in his hotel bathroom at 9:10 a.m. on Friday.
