When and where did the term "third world" originate?

I’ve often wondered how the term “third world” was coined. Does anyone know?

Cecil(in 1984) said

The expression was used at a conference of African and Asian countries in Bandung, Indonesia, in 1955 and was the title of a book published by Sauvy’s associates in 1956. It became the title of a journal in 1959 and from there passed into general usage in France. Eventually it made the leap into English.

.

There is a cite from 1958 in the Washington Post that uses the English term.

Not bad work, Cece, considering you did that 22 years ago.
