The 1999 film "Tea with Mussolini" is based on whose autobiography?

Gian Franco Corsi "Franco" Zeffirelli (12 February 1923 – 15 June 2019) was an Italian director and producer of operas, films, and television. Zeffirelli was born Gian Franco Corsi Zeffirelli in the outskirts of Florence, Tuscany, Italy. He was the result of an affair between Florentine Alaide Garosi, a fashion designer, and Ottorino Corsi, a wool and silk dealer from Vinci.

Since both were married, Alaide was unable to use her surname or Corsi's for her child. She came up with "Zeffiretti", which are the "little breezes" mentioned in Mozart's opera Idomeneo, of which she was quite fond. However, it was misspelled in the register and became Zeffirelli. When he was six years old, his mother died and he subsequently grew up under the auspices of the English expatriate community and was particularly involved with the so-called Scorpioni (a small group of elderly English ladies who lived in Florence in the 1930s and 1940s), who inspired his semi-autobiographical film "Tea with Mussolini" (1999).
