Legal and Judicial Career
Hopkinson's professional life was rooted in the law. As a young barrister, he began his ascent by serving as the deputy to Charles Read, the Clerk of the Orphans' Court of Philadelphia. Following Read's death, Hopkinson was commissioned as his successor on January 20, 1736–7, a position he held until his passing on November 5, 1751.
His judicial influence extended far beyond a single court. He was commissioned as the Master of Rolls for the city, serving until 1741. Over the years, he held several high-ranking positions, including Justice in 1749 and Judge of the Vice Admiralty of the Province between 1744 and 1745. His commitment to governance was further evidenced by his membership in the Common Council (1741) and the Provincial Council (1747).
In the latter part of his career, Hopkinson worked under James Hamilton, initially as Deputy Prothonotary (the chief clerk of a court) before being promoted to Prothonotary in 1748, a role he maintained until his death.
Commerce and Civic Leadership
Beyond the courtroom, Hopkinson was a successful merchant. He served as an agent for various London firms and entered into a partnership with William Coleman. Together, they imported and sold a diverse array of goods, including iron, gunpowder, spices, and fabrics.
Hopkinson was also a vigilant protector of his community. In 1747, he was the first to identify Spanish incursions into Delaware Bay. He took a leading role in alerting the public and was instrumental in raising the necessary funds to defend the city.
Intellectual and Social Contributions
Hopkinson was a cornerstone of Philadelphia's intellectual awakening. He was a founder of the Library Company of Philadelphia and served as an original trustee of the College of Philadelphia, which is known today as the University of Pennsylvania. Furthermore, he had the honor of serving as the first president of the American Philosophical Society.
His interest in science led to a close collaboration with Benjamin Franklin. Hopkinson was a member of the Junto, a mutual improvement society, and assisted Franklin with several electricity experiments. Franklin later praised Hopkinson's "virtue and integrity," specifically noting that Hopkinson was the one who first informed him about the power of points to discharge electrical fire.
Socially, Hopkinson was an active Freemason, belonging to St. John's Lodge and serving as the Grand Master of Pennsylvania in 1736. He was also an early subscriber of the Dancing Assembly.
Personal Life and Family
In 1736, Thomas Hopkinson married Mary Johnson. The couple had eight children. Their son, Francis Hopkinson, was enrolled in the first classes at the Academy and would eventually become a signatory of the Declaration of Independence. The family's social standing was further cemented through the marriages of his daughters to Dr. John Morgan and Reverend Jacob Duché.
