I think there are two typical paths to widespread visibility across CS subfields: (1) publishing a widely-adopted textbook, and (2) writing commonly-used software. For example, many computer scientists know about Patterson and Hennessy due to their famous computer architecture textbooks, and many computer scientists know about people like Jeff Dean due to their software.
Reading more academically-oriented literature such as the ACM’s monthly periodical “Communications of the ACM” is also a good way to get acquainted with the latest developments of computer science.
Programming Language Research (categorized by subjects) - https://www.cs.cmu.edu/~mleone/language-research.html
Nevertheless, a useful starting page to begin one's research from.
Somebody needs to create a similar list for current times. Maybe the co-author of "Elements of Programming" and preserver of "Software History" artifacts, named Paul McJones would be the right person? ;-)
I especially hate those who attempt to design new programming languages today, but then demonstrate a complete lack of awareness about the history of programming languages, by introducing a lot of design errors in their languages, which had been discussed decades ago and for which good solutions had been found at that time, but those solutions were implemented in languages that never reached the popularity of C and its descendants, so only few know about them today.

Does not compute.
Your comment is mere empty verbiage with no information.
You made a preposterous statement, got called out, and are now making excuses.
Anybody who claims to have studied "Theoretical Computer Science" can/will never make the statements that you did (and that too in a thread to do with Niklaus Wirth's achievements who was one of the most "practical" of "theoretical computer scientists"!).
