Son of Jan Louis van Hardenbroek (d. 1747) and Jeanne Charlotte van Renesse (1695?-1723).
In 1755 he bought Bergestein from the Borre de Amerongen family, enabling him to join the Utrecht "corps of nobles", which he did in 1758. Stewart-General of Utrecht. Utrecht representative in the Amsterdam chamber of the East-India Company (1759-1764). Deputy to the States General (1767-1785).
According to Strier, van Hardenbroek proposed to Belle de Zuylen at some time after 1767 (probably in 1770), but at a time when she had already decided to marry Charles-Emmanuel de Charriere and leave Utrecht.1
