Halliwell-Phillipps, James Orchard, a celebrated Shakespearian scholar and antiquary, born at Chelsea; studied at Cambridge; his love for literary antiquities manifested itself at an early age, and his research in ballad literature and folk-lore, &c., had gained him election as Fellow to the Royal and Antiquarian Societies at the early age of 19; devoting himself more particularly to Shakespeare, he in 1848 published his famous “Outlines of the Life of Shakespeare,” which has grown in fulness of detail with successive editions, and remains the most authoritative account of Shakespeare's life we have; his “Dictionary of Archaic and Provincial Words” is also a work of wide scholarship; having succeeded in 1872 to the property of his father-in-law, Thomas Phillipps, he added Phillipps to his own surname (1820‒1889).
