#Programming languages I know (for various definitions of “know”) by decade of invention:

10s: #Rust, #Elixir, #Crystal
00s: #Clojure
90s: #Ruby, #Python, #JavaScript
80s: #Perl
70s: #C, #Scheme
60s: #BASIC
50s: (none)

Is there a language from the fifties worth learning?
@seven1m since you already got lisps in your pocket, I'd say probably none. Unless you have to deal with some legacy system :-)
