b. 4 Feb. 1874 at Talysarn, Caerns. , son of James Wallace and Katherine Fagan . He was educated in the local school, Denstone College , and Gonville and Caius College , Cambridge , and graduated in 1898 . He was for a short period chemistry master in Abertillery secondary school (his successor in that post was Thomas Jacob Thomas , ‘ Sarnicol ’; see below ), and then went to study under the professors Dobbie and Winter at University College , Bangor .

In collaboration with the Welsh Plant Breeding Station between 1919 and 1939 Fagan became one of the leading British scientists studying the chemistry of grass and its conservation . He was a pioneer in this field and his articles, most of which were published in the Welsh Jnl. of Agric. , bear testimony to his ability, dedication and leadership as an agricultural scientist . His meticulous and accurate analyses were of inestimable value to plant breeders , and according to R.G. Stapledon (see below) Fagan laid sure foundations for understanding the innumerable factors affecting the nutritive value of grasses, clovers, and other grassland plants. He continued his researches to the end of his life, but did not receive the commendation which was due to him for his pioneering work, possibly because he was by nature unassuming, and reluctant to extol the value of his own researches.
