Diana Kennedy (born 3 March 1923) is an authority on Mexican cooking known for her nine books on the subject, including The Cuisines of Mexico, which started changing how Americans view Mexican cooking.
Her work is the basis of much of the work of Mexican chefs in the United States.
Her cookbooks are distinctive because they are based on her fifty years of traveling Mexico, interviewing and learning from cooks of all kinds in the country, and from just about every region.
Her work has also documented native edible plants, which has been digitized by National Commission for Knowledge and Use of Biodiversity.
Due to her style of work, Kennedy has been called a "culinary anthropologist" and has self-identified as an "ethno-gastronomer".
Kennedy has received numerous awards for her work, including the Order of the Aztec Eagle from the Mexican government and was appointed a Member of the Order of the British Empire.
