I've heard similar opinions before and considered them plausible in the past, mostly based on this idea that there were people who "invented" in multiple disciplines in a way that seems impossible today. However, now I wonder if that might be more an effect of the increasing level of communication among humans in general at the time, printing presses, steamships, postal organizations, newsletters, etc, all combined to cause ideas to spread much more widely and more quickly than they did in the past. Perhaps its more a function of being the first (or most popular) person to synthesize certain ideas based on being at the intersection of spreading knowledge.
