Richard G Lyons, who doesn't seem to have a Wikipedia page, gets linked here at /r/ECE frequently. He supposedly is a "pioneer" of DSP. I thought he had a blog over at EmbeddedRelated.com, but don't see it now. His DSP book is in the third edition. I started reading it and liked it. He writes more like an engineer than a mathematician. I haven't finished it because I stopped to work on my math skills..
