Mike Wolf and Jerry Williams saved - and created - the modern 3RO hobby. They both leveraged the Lionel image (if not the name) far better than Lionel did for a long time. Maybe ever. Without their "extension" of 3RO into scale and scale-like product, even Richard Kughn could not have saved Lionel - there was really nothing to save, had it remained what it was.
Let's not forget Maury Klein, and a host of others (R-O-W's founder comes to mind).
Lionel, though - they got the command control right. Not sure now that it's as "right" as it once was.
