Girolamo Manfrin (1742 – 1801) was a Dalmatian Italian entrepreneur active in Venice in the 18th century.
He was born in Zara (today Zadar, Croatia) in the Republic of Venice.
[1] V. Spreti traced his line back to a Manfredo created count in 1433.
He struggled in Venice in the beginning, ending up in jail after he refused to reveal (as it was customary) the names of the investors of the tender for conducting Venice's tobacco trade, which he had won.
[1] He had a famous art collection comprising the Portrait of Johannes Wtenbogaert by Rembrandt, today in the Rijksmuseum in Amsterdam.
