Blast of Giant Atom Created Our Universe, from the December, 1932 issue of Popular Science. From the (2007) introduction:

This is a pretty amazing article. It’s a concise summary of the big bang theory published only 3 years after Edwin Hubble made his famous observations about the redshifts of distant galaxies. Yet it’s pretty much identical to one you’d see today. Only a few details like the size of the initial “atom” and the age of the universe seem off. Keep in mind it took another 35 years or so before the scientific community came to accept that the big bang really happened.

Found via a post at Cosmic Variance, which emphasizes the work of Father Georges-Henri Lemaître, and concludes

Lemaître passed away in 1966, a year after Penzias and Wilson detected the microwave radiation leftover from the Primeval Atom.

I.e, Lemaître lived long enough to see his work confirmed by observation.
