Between 1450 and 1452, to finance his experiments, he had
borrowed 1,600 guilders from Johann Fust, a local banker.
Inventors are not usually much good at running their affairs

Fust, in contrast, was particularly hard-headed and hard-hearted.
So aggressively impatient did Fust become, not only to see a

lion's share of any profits, that in 1455 he sued Gutenberg for
repayment of capital and interest amounting to 2,026 guilders.
When judgment was given in Fust's favor he foreclosed on his loan
