To Thomas Bruff
Monticello June 7. 12.
I have duly recieved your letter of May 30. and am very happy to learn that your manufactory of solid shot is likely to get into operation; while their quality will command a preference in the private demand, there can be no doubt but the same circumstance will ensure you the public supply. having other occasion to write to the president I have with pleasure added a recommendation of yourself and your manufactory to his attention. wishing you all possible success, I tender you the assurance of my esteem & respect.

Thomas Bruff (ca. 1772–1816), dentist and inventor, moved about 1799 from Chestertown, Maryland, to a succession of residences in and near Washington, D.C. Between 1797 and 1813 he received five patents for improvements in tooth extraction, coffee grinding, silver-spoon manufacture, and production of musket balls and shot by pressure. Bruff met TJ in 1801 in connection with his unsuccessful efforts to obtain congressional support for his perpetual time and motion machine, and he subsequently described other inventions to TJ, including a fire engine and a horizontal windmill. TJ paid him for dental services on three occasions between 1803 and 1808 and later recalled his “inexhaustible ingenuity.” Bruff constructed a pressed-shot factory, which was destroyed in the Washington Navy Yard fire of August 1814. He died in New York City (List of Patents description begins A List of Patents granted by the United States from April 10, 1790, to December 31, 1836, 1872 description ends , 15, 16, 25, 68, 126; Keene, N.H., Rising Sun, 23 Dec. 1797; Centinel of Liberty, or George-Town and Washington Advertiser, 29 Nov. 1799; New York Mercantile Advertiser, 26 Sept. 1801; PTJ description begins Julian P.
