Jethro Bithelll was born at Hindley near Wigan in 1878. He was educated at Wigan Technical School and Owens College, in the Victoria University of Manchester, where he graduated with a first class degree in modern languages in 1900. He then studied German and Scandinavian literature at the Universities of Munich and Copenhagen.
From 1902-1904 he lectured in modern languages at Salford Technical College, and from 1904-1910 he was a lecturer in German at Manchester University. In 1910 he married his first wife, Ethel Rose Fisher (d 1946) and was appointed head of the Department of German at Birkbeck College London. In 1921 he was elected Reader in the University of London, but never became a full professor. He remained at Birkbeck until his retirement in 1938.
During World War One he served as a Private in the Royal Sussex Regiment, Oct 1916-Jan 1919. In 1947 Bithell married again to Dr Alice Emily Eastlake, a long standing friend of himself and his first wife.
Bithell belonged to the group of British born Germanisten who sought to turn German Studies in a new direction, breaking away from the positevistic and philological approach perpetrated by their German-born teachers. He believed, in common with other Germanisten such as William Rose, that literature was a social phenomenon and this attitude is best exemplified by his book Germany, 1932, a collection of essays on all aspects of the artstic and intellectual life of Germany set against its climate and geography. He was aware of a wider need for text book support in language studies and compiled dictionaries, readers and grammars in German and French.
His studies embraced medieval and modern language and literature from not only Germany, but also France, Belgium (including Flemish) and Norway. In retirement he continued to act as an examiner for schools and universities in German. Marking for the Higher School Certificate prompted him to compile his Anthology of German Poetry, 1880-1940, (1941) and two other anthologies followed. He had an abiding love of poetry in several languages. His superlative translation of the Minnesingers in 1909 earned him an entry in Who's Who and his translations from the work of Henrik Wergeland were considered by many to be a "tour de force".
He worked with Professor Andrew Gillies, who was editor of the Germanic Section of the Modern Language Review. During World War Two, the numbers of Germanisten available for review work were greatly reduced, and Gillies asked Bithell to oblige, which he did. At this time he popularised the work of Carossa, and demonstrated that not all Germans were Nazis or Nazi sympathisers. Bithell was also a keen supporter and contributor to German Life and Letters, which honoured his 80th birthday (1958) with a Festschrift volume.
