In 1860, pharmacists John (1834–1907) and Frank Wyeth opened a drugstore with a small research lab on Walnut Street in Philadelphia. In 1862, on the suggestion of doctors, they began to manufacture large quantities of commonly ordered medicines. They were successful, and in 1864 they began supplying medicines and beef extract to the Union army during the Civil War.

In 1872, Henry Bower, an employee of Wyeth, developed one of the first rotary compressed tablet machines in the United States. This enabled the mass production of medicines with unprecedented precision and speed. It was successful, and the Wyeth brothers won multiple awards at the Centennial Exhibition. In 1883, Wyeth opened its first international facility in Montreal, Canada, and began vaccine production. Six years later a fire destroyed the brothers' original Walnut Street store, and they sold the retail business and focused on mass production.
I guess we can thank them for medicine "tablets".
