phrase origin

Hi guys,
I was wondering whether anyone knows when & where did the phrase ‘concrete/asphalt jungle’ originate? Who coined it basically? Do post the answers if anyone knows!

Well, The Asphalt Jungle was the title of a John Huston movie from 1950 which was based on a novel by the same name. Don’t know if that was where the phrase originated though.

Obligitory IMDB Reference

There is an OED cite to the term “Asphalt Jungle” from 1920 thusly

I can’t offer much about what it meant. And, of course, Upton Sinclair started it all in 1906 when he wrote The Jungle.

I think “concrete jungle” is a phrase that appears much later, perhaps the 60’s.

Ok, I’ve never seen the film-- is it a version of Upton Sinclair’s “The Jungle”? Or is it adapted from something else?
