Although he became one of the first professors at Princeton's Institute for Advanced Study (where no teaching was required) in 1936, he continued to lecture at Oxford during Trinity terms until 1948.

[1] Lowe wrote several important works on early medieval palaeography, including The Beneventan Script (his 1914 study of the oldest extant manuscript of St Benedict's rule), and his collected Palaeographical Papers, 1907–1965 (published posthumously in 1972).

He remains best known, however, for the eleven-volume Codices Latini Antiquiores (CLA) which offers a palaeographical guide to all extant Latin literary manuscripts copied in scripts antedating the ninth century.

[1][2] An internationally respected authority in his field, Lowe received formal recognition from numerous academies, institutes, and scholarly societies.

Towards the end of his life he told one of his daughters that, were he to adhere to a religion, he would opt for Roman Catholicism.
