This is a list of inventors whose deaths were in some manner caused by or related to a product, process, procedure, or other innovation that they invented or designed.

Direct casualties

Art

• Luis Jiménez (1940–2006) was killed while creating the Blue Mustang, a blue horse statue located on the grounds of the Denver International Airport, when a section of it fell on him and severed an artery in his leg.^[1]

Automotive

• Sylvester H. Roper (1823–1896), inventor of the Roper steam velocipede, died of a heart attack or subsequent crash during a public speed trial in 1896. It is unknown whether the crash caused the heart attack or the heart attack caused the crash.^[2]
• William Nelson (c. 1879–1903), a General Electric employee, invented a new way to motorize bicycles. He then fell off his prototype bike during a test run.^[3]
• Francis Edgar Stanley (1849–1918) was killed while driving a Stanley Steamer automobile. He drove his car into a woodpile while attempting to avoid farm wagons travelling side by side on the road.^[4]
• Fred Duesenberg (1876–1932) was killed in a high-speed road accident in a Duesenberg automobile.^[5]

Aviation

• Ismail ibn Hammad al-Jawhari (died c. 1003–1010), a Kazakh Turkic scholar from Farab, attempted to fly using two wooden wings and a rope. He leapt from the roof of a mosque in Nishapur and fell to his death.^[6]
• Jean-François Pilâtre de Rozier was the first known fatality in an air crash when his Rozière balloon crashed on 15 June 1785 while he and Pierre Romain attempted to cross the English Channel.
• Robert Cocking (1776–1837) died when his homemade parachute failed. Cocking failed to include the weight of the parachute in his calculations.^[7]
• Otto Lilienthal (1848–1896) died from injuries sustained in a crash of his hang glider.^[8]
• Percy Pilcher (1867–1899) died after crashing his glider, having been prevented from demonstrating his powered aircraft.
• Franz Reichelt (1879–1912), a tailor, fell to his death from the first deck of the Eiffel Tower while testing his invention, the coat parachute. It was his first attempt with the parachute; he had told the authorities he would first test it with a dummy.^[9]

Chemistry

• Marie Skłodowska Curie (1867–1934), born Maria Salomea Skłodowska, was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. On 4 July 1934, she died at the Sancellemoz sanatorium in Passy, Haute-Savoie, from aplastic anaemia believed to have been contracted from her long-term exposure to radiation, some of which was from the devices she created.^[17]
• Sabin Arnold von Sochocky (1883–1928) invented the first radium-based luminescent paint, but eventually died of aplastic anemia resulting from his exposure to the radioactive material.^[18]
• Andrei Zheleznyakov (died 1993), a Soviet scientist, was developing chemical weapons in 1987 when a hood malfunction exposed him to traces of the nerve agent A-232. He spent weeks in a coma, months unable to walk, and years of failing health before dying from its effects six years after being exposed.^[19]

Industrial

• William Bullock (1813–1867) invented the web rotary printing press.^[20][21] Several years after its invention, his foot was crushed during the installation of a new machine in Philadelphia. The crushed foot developed gangrene and Bullock died during the amputation.^[22]

Maritime

• Henry Winstanley (1644–1703) built the
