Wikipedia on "Hippie"

[Fred Shapiro]

OED's first use of _hippie_ is dated 1953.  FWIW, Wikipedia claims the
following:

Like the word "hipster", the word "hippie" is jazz slang from the 1940s"
One of the first recorded usages of the word "hippie" was in a radio show of
November 13, 1945, in which Stan Kenton called Harry Gibson a hippie (NBC
studios, live radio program, the "Jubilee" show at Billy Berg's jazz club in
Hollywood, CA, and recorded through the transcription service of the Armed
Forces Radio Corps, or AFRC, and available on the CD "Stan Kenton And Friends,"
2006).
