Barium was discovered by Sir Humphrey Davy at 1808 in England. Origin of name: from the Greek word barys meaning heavy Baryta (barium oxide, BaO) was distinguished from lime (calcium oxide, CaO) by Scheele in 1774.
During that research, a team from the University of California, consisting of Glenn Seaborg (1912-), Albert Ghiorso (1919-), Ralph A. James, and Leon O. Morgan (1919-), discovered a new element, which would eventually be named americium.
