In 1961 werd lawrencium ontdekt door Albert Ghiorso, Torbjorn Sikkeland, Almon Larsh en Robert M. Latimer aan de Universiteit van Californië - Berkeley. Zij produceerden het element door 3 milligram californium te bombarderen met boorionen in de Heavy Ion Linear Accelerator (HILAC). Het hieruit ontstane element met een atoomnummer 103 en een massa van 257 verviel met een halveringstijd van 4,2 seconden onder uitstraling van alfadeeltjes weer uiteen.
