John Martyn Roberts

Martyn John Roberts FRSE DL (1806–1878) was a 19th-century Welsh scientist and inventor who performed experiments with his unique galvanic battery for controlled explosion and contributed to innovations in conductors, photography theory, voltometry, electric light and much more.

He was born in Wales on 2 August 1806 the son of Caroline Yalden of Lovington and her husband, John Roberts.

[3] He also in the same year patented a device to reduce friction on ships propellers but this lapsed in 1867 due to non-payment of the £50 stamp duty.

He is buried in Llangenny Churchyard with his son beneath a majestic ornately decorated obelisk.

He was a deeply caring man whose innovations characterise a most humanitarian inventor of science but who sadly, lies unknown, forgotten and uncelebrated in "The Land of his Mothers & Fathers".
