As mentioned, they are different domains. How about Claude Shannon? He has the right to be called as influential as Turing within the information engineering world. Basically his work laid the foundation for making digital ALUs possible. Not to mention his enormous contributions to information theory. How about Alan Kay, who invented (or discovered) object oriented programming? How about John McCarthy who invented Lisp? And, moreover, the idea of macros. Many of the things we take for granted on modern platforms (for example, garbage collection) originated with Lisp, so the invention of Lisp laid a foundation for the evolution of programming languages.
