“Stimuli to induce him to be useful to this Country”
For example, did the former Woburn farmboy, royal government undersecretary, and British cavalry officer cross paths with John Adams, minister to Britain in the 1780s?
It appears that the two men never met since the first letters they exchanged, in 1796, show no personal acquaintance. By then Thompson had become the celebrated Count Rumford, and he was sending Adams a volume of his scientific papers and a large sum to endow a prize through the American Academy of Arts and Sciences. Rumford continued sending volumes to Adams through the Rev. William Walter.
In 1799, Abigail Adams wrote of “Rumfording our Chimney’s, which I shall be for trying. I am persuaded half the expence of fuel may be saved, and Rooms kept equally warm.” The Woburn native had become famous enough to be a verb.
In 1820, John Adams sent off multiple letters pursuing the theory that “the late learned ingenious scientific public Spirited and benevolent Count Rumford” was a descendant of “the well known Rev. William Tompson of Braintree.” (He was not.)
But the most striking intersection between Rumford and Adams arose in June 1799, when Adams’s secretary of war, James McHenry, wrote about inducing the count to offer his talents to the U.S. Army:
I think it was mentioned to you, some time last winter, by the Secretary of State [Timothy Pickering], in consequence of a letter he had just received from Mr. [Rufus] King [minister to Britain 1796–1803 and 1825–26], that Count Rumford intended to visit his native country, at which you seemed pleased, and expressed yourself favourably of his talents.Adams had no idea that back in 1775 Thompson had been slipping secret intelligence to Gen. Thomas Gage—a fact that would probably have changed his admiration for the man.
Mr. King has renewed the subject to the Secretary of State, and in a letter to me, which I have the honour to inclose. As the reference of the subject to me, can only be meant so far as it respects the military department, I beg leave to submit for your consideration, whether it would not be to the advantage of the United States to make such a proposal to the Count, which if accepted, would ensure to the army the full benefits of his skill and experience.
There is still a vacancy of Lt. Colonel, to be filled for one of the Regiments of Artillerists & Engineers. . . .
1. He may be offered the vacant commission of Lt. Colonel and be made also Inspector of Artillery. Or if he prefers it. 2d. He may be invited to accept of the office of Engineer…
As I consider him to be less of an Engineer than an Artillerist, altho in this I may be mistaken I should think it most adviseable to give a preference to the first proposition. If he accepts of it, he can also superintend the establishment of a military academy which the laws so far contemplate, as to have made provision for books, instruments, and teachers.
At any rate, if the Count should refuse himself to either office, the offer cannot be otherwise than grateful, and if he wanted any stimuli to induce him to be useful to this Country, to the extent of his talents, it might have its effect.
As for Rumford, it’s hard to imagine that a man who had administered an entire country in Europe could be swayed by the prospect of being a lieutenant colonel in America. He never did come back.
