A. L. Armstrong, Dictionary of National Biography… (1912)
“ Harcourt ranks with the few men who could talk as brilliantly as they could write. He was an indefatigable worker, and his speeches, which were monuments of closely reasoned arguments, teeming with facts and illuminated by witty epigrams, were generally most diligently prepared and delivered by the aid of copious notes. He was at his best, however, when suddenly called upon to debate, and was never so happy as when he was fighting a hopeless battle against overwhelming odds. ”
