Geskiendenis
Lawrencium was discovered by Albert Ghiorso, Torbjørn Sikkeland, Almon Larsh and Robert M. Latimer in 1961 at the University of California, Berkeley.
It was produced by the bombardment of californium with boron atoms.
Lawrencium was the last member of the actinide series to be discovered.
