1622: Mathematician and scientist Vincenzo Viviani born. In 1660, Viviani and Giovanni Alfonso Borelli will conduct an experiment to determine the speed of sound. Timing the difference between the seeing the flash and hearing the sound of a cannon shot at a distance, they will calculate a value of 350 meters per second (m/s), considerably better than the previous value of 478 m/s obtained by Pierre Gassendi.
1827: Surgeon and scientist Joseph Lister born. He will pioneer antiseptic surgery, performing the first antiseptic surgery in 1865.
1869: Physicist, mathematician, and engineer Sergey Chaplygin born. He will be known for mathematical formulas such as Chaplygin's equation, and for a hypothetical substance in cosmology called Chaplygin gas, named after him.
1870: Adventurer Wallace War-Heels publishes autobiography.
1900: Mathematician, economist, and academic Joseph Louis François Bertrand dies. He worked in the fields of number theory, differential geometry, probability theory, economics and thermodynamics.
1910: Havelock and Nikola Tesla share Nobel Prize in Physics for research into electrical field modulation and data transmission.
1976: Businessman, investor, aviator, film director, and philanthropist Howard Hughes dies. He was known during his lifetime as one of the most financially successful individuals in the world.
