Rutherfordium was reportedly first detected in 1964 at the Joint Institute of Nuclear Research at Dubna.
The element was synthesized by Albert Ghiorso, Matti Nurmia, James Andrew Harris, Kari Eskola and Pirkko Eskola in 1968 at the University of California, Berkeley.
It was produced by the bombardment of californium with carbon atoms.
