1741-1811

Thomas Fitzsimmons does not appear to have been a prominent member of the convention which framed the constitution. Nor does his name appear in connection with the movements of his fellow-citizens during the Revolution. But as there were no men of mean capacity in the convention, we may suppose that Mr. Fitzsimmons was, by talent and energy, rendered worthy of the high legislative trust which the people of his native State saw fit to place in his hands.
