French Formulated an eponymous Law stating that the force of attraction between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them; A unit for the quantity of electricity was named after him.
Austrian Discovered (1842) that the apparent change in the frequency of sound, light, or radio waves is caused by a change in the distance between the source of the wave and the receiver.
