Analysis of information sources in references of the Wikipedia article "Johann Fust" in English language version.
The goldsmith bankers were private bankers who did practically all the banking business in Western Europe during the seventeenth century and before. People who possessed gold deposited it with the goldsmiths for safekeeping.
Others held that Fust was the greedy money man who robbed poor Gutenberg of his invention, his business, and his fortune, leaving him penniless. [...] None of this, it now seems, is true.
