Carruthers was born in Dublin, Ireland in 1949, and would graduate from University College Dublin with degrees in English and History.
He began research at the University of Paris-Sorbonne in France in 1977, and would become a third cycle doctor of both Comparative Literature and English Medieval Literature. Much later in 2016, he became a Professor Emeritus there.
For his expertise, Carruthers has appeared in three French-made documentaries concerning Tolkien and The Lord of the Rings: in 2013 he was interviewed for Simon Backès' 2014 documentary Tolkien: The Words, The Worlds. Later, Carruthers, John Howe, and French story-teller Nicholas Mezzalira were the primary expert cast of Olivier Simonnet's 5-episode documentary Looking for the Hobbit. Carruthers is introduced at Exeter College, Oxford University, meets some members of the Tolkien Society at The Eagle and Child, and informs John Howe about Tolkien's Medieval literature influences, among other things. Again in 2014, Carruthers was interviewed for the making of JRR Tolkien, le seigneur des écrivains, a project of François Busnel's talk-show La Grande Librarie.
