Hassard was descended from Dorset merchants active in both Lyme Regis and Bridport.
Hassard sat for Lyme Regis in the 1621 Parliament, the first of his family to represent the borough since his great-uncle John in 1604-10. He received no appointments, but on 17 May he drew on his specialist knowledge of the gold trade, gained in the Jewel House, to denounce Sir Edward Villiers*: ‘There is a monopoly of gold weights, and albeit it be not by a patent, yet it is by a Proclamation, and a great grievance.’
By 1624 Hassard had won promotion at Court, becoming an esquire of the body to James I. He is known to have written from London to his father in Dorset in December 1623, conceivably alerting him to the imminent parliamentary elections, in which he was again returned for Lyme Regis. A month later, while waiting to resume his Commons’ seat, he lobbied the government on behalf of a Lyme man whose ship had been requisitioned for military service.
