David Daggett (1764-1851) was an American senator, mayor of New Haven, Connecticut, Judge of the Connecticut Supreme Court of Errors, and a founder of the Yale Law School. He wrote under the pen name Jonathan Steadfast. He studied law under Charles Chauncey of New Haven. He supported himself by working as a butler and as a preceptor at Hopkins Grammar School. In January 1786, he was admitted to the bar of New Haven County and immediately set up his own practice, turning down an offer to be a tutor at Yale. In 1791, he was chosen to represent the town of New Haven in the General Assembly. Though one of the youngest members of the House, he soon became one of the most influential, and in 1794, three years after he entered it, he was chosen to preside over it as Speaker, at the age of 29. He helped to draft the resolutions against the "Negro college", and spoke publicly at an 1831 town meeting against the college. He was among the most influential opponents of Simeon Jocelyn's plan.
