John Jones (1818–1898), also known as Ioan Bryngwyn Bach and Y Seryddwr, was a Welsh amateur astronomer.[1]

Jones was born at Bryngwyn Bach, Dwyran, Anglesey, and received only an elementary education. From the age of twelve, he worked as a farm labourer, and later in the slate industry. Unusually for someone of his background, he was not only a musician and poet but proficient in several languages. However, he is noted mainly for his interest in astronomy: he constructed his own telescopes, including "Jumbo", reputed to be the first silver-on-glass reflecting telescope in Wales.[2]


Jones was praised by Samuel Smiles in his 1884 book Men of Invention and Industry, and in 2004, he was voted no 93 in a poll of 100 Welsh Heroes run by the BBC.[3] A plaque in his honour was erected by Ynys Môn County Council at Brynsiencyn.
