He was educated in the primary school at Melin-y-Wîg — a name revived by him — 1910-18 , and Bala grammar school , 1918-24 , before entering the University College of Wales at Bangor in 1924 . There he became secretary of the Students’ Union and succeeded in making Welsh jointly official with English . He was a leading member of the society of the three G's — ‘ Y Tair G ' — one of the three streams that united to found Plaid Genedlaethol Cymru — in Aug. 1925 . He was appointed secretary of the college branch of the Party when it was formed in Nov. 1926 , and topped the poll when he stood as a nationalist in a mock election. He graduated in 1927 .
After he had taken a post as a teacher in London in 1928 a branch of the Party was founded there with J.E. again as secretary . As a result of his extraordinary organising talent the branch flourished and became the largest in the Party. He returned to Wales in 1930 as secretary and organiser of Plaid Genedlaethol Cymru . In Glan-rhyd (Presb.) chapel on 27 July 1940 he m. Olwen Roberts , the sister of John Iorwerth Roberts , and they had a son and daughter.
He possessed a tough character, a strong mind and patience. The great strength of his personality was often camouflaged by his gentleness. In addition to his work as secretary of the executive committee of the Party , he organised the annual conference and summer school , and also rallies. He developed these into strong organisations but he also stimulated the formation of branches up and down the country. Apart from his responsibilities at local and parliamentary elections (he himself stood as a candidate in Caernarfon in 1950 ), he organised many special campaigns, such as those for radio and television, for a development corporation, against the extreme schemes of the Forestry Commission and against the appropriation of land in Wales by the War Office ; the military camp at Trawsfynydd was twice surrounded by members of the Party. The campaign against the flooding of Cwm Tryweryn became very strong; but no doubt the campaign against the Bombing School in Llŷn in 1935 was the most notable, with the imprisonment of Saunders Lewis , Lewis Valentine and D.J. Williams . These numerous operations demanded great effort in gaining the country's support. He contributed more than anyone to the great feat of keeping Plaid Cymru together during World War II .
He took care of press releases and all publicity, and occasionally he had to shoulder most of the load in publishing the Party's papers, Y Ddraig Goch and Welsh Nation . More than a hundred books and pamphlets were published during his term as secretary . He also built up the St. David's Day Fund as the Party's main financial source.
He lectured and prepared television series on gardening , on which he was an expert. In addition to a valuable volume on the subject, he wrote a travel book about Switzerland . But his most valuable work is Tros Gymru , which is a mine of information on Plaid Cymru up to 1945 . In addition to all this, he was the Sunday school teacher of a large class of young women in Heol y Crwys (Presb.) chapel , Cardiff .
In 1962 ill health compelled him to relinquish his post as secretary of Plaid Cymru and take a lighter position as its advisor . He was on his way home from the office, during the general election, when he d. suddenly, 30 May 1970 . He was buried in Melin-y-Wîg cemetery. He is regarded as the chief architect of Plaid Cymru .
