Robert Isaac Jones

Robert Isaac Jones (1813 – 7 March 1905), also known under his bardic name Alltud Eifion, was a Welsh pharmacist, writer, and printer.

He gained some fame as the peddler of "Tremadoc Pills", which he claimed as an effective medicine for many different illnesses.

[1] Jones was a keen printer, starting a Tremadoc printing-press where he printed several Welsh-language publications.

[1] Jones also published a biography of early black Welsh gardener, John Ystumllyn (d. 1786), collated from his family and local area's oral sources.

He contributed to several religious journals - Yr Haul, Y Llan, and Cymru - and briefly refounded a pre-existing church periodical, Baner y Groes.
