Leon Foucault Facts
Jean Bernard Léon Foucault (French pronunciation (September 18, 1819 to February 11, 1868) was a French physicist. He is best known for his demonstration of the Foucault pendulum, a device demonstrating that the Earth rotates on its axis. He made a very accurate measurement of the speed of light.
Interesting Leon Foucault Facts:
Foucault was born in Paris and was the son of a publisher.
He received his early education at home and then attended College Stanislas.
He studied medicine under Alfred Francois Donne but he had an aptitude for mechanical devices and changed his major to physics.
He became interested in photography and worked with Armand Hippolyte Louis Fizeau.
Foucault discovered a way to take photographs through a microscope and he invented a strong light to illuminate the subjects.
In 1845 he took over Alfred Francois Donne's position as editor of the Journal des Debats.
In the early 1850's he invented his famous pendulum and in 1852 he further demonstrated the earth's rotation with a gyroscope.
For his proof of the earth's rotation he was awarded the Copley Medal of the Royal Society.
In 1855 he became the physicist of the Imperial Observatory where he experimented with telescopes and land-surveying equipment.
He studied the use of silvered concave mirrors to improve telescope technology.
In 1862 Foucault used a rotating mirror in an enclosed space to accurately determine the speed of light and he became interested in precision engineering.
In July 1867 he suffered a stroke and died the following February.
There is some speculation that the chemicals he used in his work contributed to his early death.
