John Todhunter (1839-1916) was a poet and playwright involved in the Irish Literary Society. Born in Dublin to a Quaker family of English origin, Todhunter, like many Irish writers of his generation was enamoured with Irish mythology and the bardic tradition. Todhunter’s most interesting work however is a historical biography of Patrick Sarsfield, the earliest authoritative historical work on Sarsfield, published in 1895.
