Essays presented to Gerald Harriss (Hambledon, 1995), a Festschrift in his honour, edited by two of his former research students, Rowena E. Archer and Simon Walker, was published in 1995. Harriss' important contributions to medieval history were based upon his research into the growing financial demands and prerogatives of late medieval English government, which resulted in a series of important articles such as "Fictitious Loans", Ec.HR, 2nd series, 8 (1955-6), pp. 187–99; "Preference at the Medieval Exchequer", BIHR, 30 (1957), pp. 17–40; and "Aids, Loans and Benevolences", Historical Journal, 6 (1963), pp. 1–19. In his magnum opus, King, Parliament and Public Finance in Medieval England to 1369 (Oxford, 1975), Harriss placed the parliamentary-controlled system of royal finance in the context of the emergence of the crown as a corporate body separate from the person of the king, and its role in the development of English political society and the constitution. Harriss later benefited from the work of Simon Walker, particularly in relation to the retinue of John of Gaunt and the development of private forms of political authority alongside that of the crown.As well as succeeding McFarlane at Magdalen, Harriss also edited a posthumous collection of McFarlane's essays, Lancastrian Kings and Lollard Knights, in 1972. In 1997, Harriss edited Letters to Friends 1940-1966, a collection of McFarlane's correspondence with several of his distinguished students, including R. R. Davies, Karl Leyser, Alan Bennett, and Harriss himself, published privately by Magdalen College. Source: Wikipedia (en)
