 John Dumbleton became Master of Arts at Oxford and Bachelor of Theology at Paris. He was listed as Fellow of Merton College in 1338 and was also a founding Fellow of Queens College in 1341. He studied theology at Paris in the mid-1340s, returning to Oxford around 1347: he was listed again at Merton in 1348. His Summa Logicae et Philosophiae Naturalis was left unfinished at his death, probably from the Black Death in 1349.
