APL introduced the name "reduce" and was the first to have it by ten years or so (published 1962, implemented 1966). Fairly sure Lisp had map first as the Each operator only appeared in nested APLs around 1981. APL may have had Compress before Lisp had filter, but they're not really the same: APL's isn't a higher order function; it takes one boolean filter list and another list to be filtered. Reduce and Compress are both denoted / which is sometimes a problem.
