Or Jean Sammet (author of a very comprehensive book on programming languages in the 1960s), or Lois Haibt (involved in development of original Fortran compiler) or Frances Allen (did key work at IBM on optimization in Fortran compilers), or Sister Mary Keller (involved in developing Dartmouth Basic), or Adele Goldberg (key developer of Smalltalk), or Barbara Liskov (CLU, and many other things)...those off the top of my head, though a web search would find many more, I'm sure.
