Gherardo Gambacorta

Gherardo Gambacorta, also known as Gaddo, was a Pisan merchant and brother of Buonaccorso, called Coscio. In 1294 he lent 262 ounces of gold to Charles II of Anjou for a journey to Rome. He served among the elders of Pisa in 1297, following his brother's election earlier that year.

The brothers held property around Pisa and in Sardinia and made loans together. Under Ranieri della Gherardesca's rule in 1321–1325, they were among the merchants charged with the largest forced loans.
