Famous modern-era academics without academic degrees? Are the any famous or well-known (today-living) researchers without academic degrees working as professors or permanent staff members?

There are two related questions:


PhD without previous academic degree: truth or myth?
Is it possible to obtain a Master&#39;s degree without Bachelor&#39;s degree?


However, I am curious about the no-degree (past upper secondary school, i.e. no BSc, MSc, PhD, etc) case.
In regard to your question's topic, at least two relevant terms come to mind: lay scholar and autodidact. Once we establish the right terminology, it is not too difficult to find information that you're looking for. In particular, this Wikipedia list and this list seem to be rather comprehensive (you will have to filter the information to select the modern-era academics without degrees).
