Logie Baird wasn't a scientiest, not even a half-way decent engineer
Baird was a crank who persisted with his plans for mechanical television well after the point that pure electronic solutions had been demonstrated to be vastly superior. I can't imagine how anybody could consider him.
One scientist that I'm surprised is not on the list: Francis Crick, who discovered (jointly with Jim Watson, but he's an American so ineligible) DNA. Surely much more notable than many of the minor figures on your list?
