Nicholas Charles HandyFRS (17 June 1941 – 2 October 2012) was a British theoretical chemist. He retired as Professor of quantum chemistry at the University of Cambridge in September 2004.
Handy wrote 320 scientific papers published in physical and theoretical chemistry journals.
Handy developed several methods in quantum chemistry and theoretical spectroscopy. His contributions have helped greatly to the understanding of:
