I get it that this guy needs to sell books, but the reason why Benjamin Rush isn't as well known as other founding fathers, is that he wasn't terribly important. As Surgeon General to the Continental Army, he undermined Washington and was dismissed. (And after the war recanted.) As a physician, he went to his grave favoring bloodletting and mercury tablets as treatments.
