Frege is all over analaytic philosophy, as I experienced it as an undergraduate in a top department. Many of the most important papers and books (Dummett, Kripke, Evans, etc) in philosophy of language, logic, mathematics take various of his positions as starting points.

I would describe Frege as the philosopher I had never heard of before showing up at a philosophy department whom I then heard the most about.

His insights were "forgotten" for a time, but have been central to discussions for several decades.
