History

Palladium was named after the asteroid Pallas, which was discovered at about the sametime. Pallas was the Greek goddess of wisdom.


Sources

Discovered in 1803 by Wollaston, Palladium is found with platinum and other metals ofthe platinum group in placer deposits of Russia, South America, North America, Ethiopia,and Australia.
