Golden Age heroes tend to often be VERY powerful (several of the magic using types, such as "The Spectre") or no more than trained human level ("Wildcat", "The Atom" etc). Because of World War II, evil nazi's were very common, as were brilliant scientists, both good and bad ("Lex Luthor" or " Dr Thaddeus Sirvana" for examples of evil scientists , I suppose that "Batman" or "Dr Mid Nite " would be science oriented heroes (I know I should look for a better example, but I can't find one easily right now ).
