Leo Robin was an American composer, lyricist and songwriter. He is probably best known for collaborating with Ralph Rainger on the 1938 Oscar-winning song "Thanks for the Memory," sung by Bob Hope and Shirley Ross in the film The Big Broadcast of 1938, and with Jule Styne on "Diamonds Are a Girl's Best Friend," a song whose witty, Cole Porter style of lyric came to be identified with its famous interpreter Marilyn Monroe.

"Thanks for the Memory" (1938) is a popular song composed by Ralph Rainger with lyrics by Leo Robin. It was introduced in the 1938 film The Big Broadcast of 1938 by Bob Hope and Shirley Ross, and recorded by Shep Fields and His Orchestra featuring John Serry Sr. on accordion in the film and vocals by Bob Goday on Bluebird Records. Dorothy Lamour's solo recording of the song was also popular, and has led to many mistakenly believing over the years that it was she who sang the tune with Hope in the film.
