Task: Question Answering
Input (English): Passage: Temperley writes: "After 1855 [Bennett] was spurred by belated honours, and occasional commissions, to compose a respectable number of significant and substantial works, though it was too late to recapture his early self-confidence." Works from his later years included the cello Sonata Duo for Piatti; a pastoral cantata, The May Queen, Op. 39, for the opening of the Leeds Town Hall in 1858; an Ode (Op. 40) with words by Alfred, Lord Tennyson for the opening of the 1862 International Exhibition in London; an Installation Ode for Cambridge University (Op. 41) with words by Charles Kingsley, which included a lament for the late Prince Albert; a symphony in G minor (Op. 43); a sacred cantata,The Woman of Samaria for the Birmingham Triennial Music Festival of 1867; and finally a second Piano Sonata (The Maid of Orleans, Op. 46). Many of these works were composed during his summer holidays which were spent at Eastbourne. The Ode for the Exhibition was the cause of a further imbroglio with Costa, who although in charge of music for the Exhibition refused to conduct anything by Bennett. Eventually it was conducted by Prosper Sainton, between works by Meyerbeer and Daniel Auber also commissioned for the occasion. The affair leaked into the press, and Costa was widely condemned for his behaviour.In March 1856 Bennett, while still teaching at the RAM and Queen's College, was elected Professor of Music at the University of Cambridge. He modernised the system of awarding music degrees, instituting viva voce examinations and requiring candidates for doctorates to first take the degree of Bachelor of Music. Two years later on 8 June 1868 the newly formed (later Royal) College of Organists awarded him an Honorary Fellowship.In 1858 came yet another clash involving Costa, when the autocratic Earl of Westmorland, the original founder of the RAM, saw fit to arrange a subscription concert for the Academy to include a Mass of his own composition, to be conducted by Costa and using the orchestra and singers of the Opera, over the heads of the Academy directors. Bennett resigned from the RAM at this overbearing behaviour, and was not to return until 1866. Towards the end of 1862 Bennett's wife died after a painful illness. His biographer W. B. Squire suggests that "he never recovered from the effects of Mrs. Bennett's death, and that henceforward a painful change in him became apparent to his friends." In 1865 Bennett again visited Leipzig where he was reunited with old friends including Ferdinand David, and his Op. 43 Symphony was performed. 
Question: What is the last name of the man who wrote that the musician who composed during his summer holidays "...never recovered from the effects of Mrs. Bennett's death"?
Output (English): Squire.
