The Nobel Prize?

Question

Has a Nobel Prize - in any of the awarded disciplines - ever been awarded to a person who did NOT have a Ph.D, or it's academic equivalent?

Answer 1

Of course. In addition to the Peace Prize, the prize for literature is a non-technical award.

Also, Leo Esaki received his Nobel prize for his work on tunnelling phenomenon, which was done prior to his PhD.:

Einstein's 5 famous papers were all published in 1905, the same year he got his doctorate. And almost all his papers had little to do with hsi doctoral thesis:

As near as can be determined, Lord Rayleigh's highest degree is an MA:

Marconi supposedly was not a doctorate:

Answer 2

The Nobel Peace Prize has often been awarded to people with no doctorate.

In the sciences, it has never happened.
