"Prince Bartholomeus Welser (25 June 1484 in Memmingen – 28 March 1561 in "Amberg im Unterallgäu") was a German banker. In 1528 he signed an agreement with Charles V, emperor of the Holy Roman Empire, granting a concession in Venezuela Province, which became Klein-Venedig until the concession was revoked in 1546." - (en.wikipedia.org 29.10.2020)
