Meitnerium was discovered by Peter Armbruster, Gottfried Münzenber (DE) and their co-workers at the Heavy Ion Research Laboratory (Gesellschaft für Schwerionenforschung, GSI) in Darmstadt, Germany in 1982. Named in honour of Lise Meitner, the Austrian physicist. It is a synthetic radioactive metal. Meitnerium was produced by bombarding bismuth-209 with iron-58.
