John Christopher "Charlie" Martin CBE (21 September 1926 – 22 March 1999) was a UK-born physicist, known colloquially as "the father of Pulsed Power". He was educated at Kings College, London. He was instrumental in the development of a US Nuclear Weapons Effects programme in the 1970s and received thanks in the history of the Defence Nuclear Agency. He was later awarded the Defence Nuclear Agency Gold Medal in 1977, one of only a few non-US citizens to receive it.
