Aspirin
Felix Hoffman
Aspirin was invented by Felix Hoffman.
Hoffmann first claimed to be the "inventor" of aspirin (as opposed to just the synthesizer) in a footnote to a German encyclopedia published in 1934, saying that his father had complained about the bitter taste of sodium salicylate, the only drug then available to treat rheumatism. The large doses (6–8 grams) of sodium salicylate that were used to treat arthritis commonly irritated the stomach lining and caused patients considerable pain and irritation.

Computer
Charles Babbage
Computer was invented by Charles Babbage.
Babbage is credited with inventing the first mechanical computer, the Difference Engine, that eventually led to more complex electronic designs, though all the essential ideas of modern computers are to be found in Babbage's Analytical Engine, programmed using a principle openly borrowed from the Jacquard loom. Babbage had a broad range of interests in addition to his work on computers covered in his book Economy of Manufactures and Machinery. His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century.
