George, an ingenious, but now almost forgotten writer, born at Old Aberdeen about 1626. He appears to have studied at Marischal College; and in 1657 he went to Oxford, where, according to Wood, "he taught a private grammar-school with good success for about 30 years." (Athen. Oxon. vol. ii., p. 506-7.) He died of a fever Aug. 28, 1687, and was buried "in the north body of the Church of St Mary Magdalen." In his work entitled Didascalocophus or the Deaf and Dumb Man's Tutor, printed at Oxford in 1680, he has the merit of anticipating some of the most scientific conclusions of the present age on the education of the deaf and dumb. "In prosecution of his general idea," says an eminent philosopher, who has done much to rescue the name of Dalgarno from oblivion, "he has treated, in one short chapter, of a Deaf Man's Dictionary; and, in another, of a Grammar for Deaf Persons; both of them containing a variety of precious hints, from which useful practical lights might be derived by all who have any concern in the tuition of children during the first stage of their education." (Dugald Stewart's Account of a Boy born Blind and Deaf, in Transactions of the Royal Society of Edinb., vol. vii.) Twenty years before the publication of his Didascalocophus, Dalgarno had given to the world a very ingenious piece entitled Ars Signorum, from which, says Mr Stewart, it appears indisputably that he was the precursor of Bishop Wilkins in his speculations concerning "a real character and a philosophical language." According to the testimony of Wood, Dalgarno communicated this piece to Wilkins before it was published, and it was from it that the latter took the hint of his celebrated work. It is highly discreditable to Wilkins that he takes no notice whatever of the name of Dalgarno; and Dr Wallis must share the same censure. That notice which the English professors, who borrowed from them, ungenerously withheld from the writings of the Scottish schoolmaster, was liberally bestowed upon them by Leibnitz, who has, on various occasions, alluded to the Ars Signorum in commendatory terms. The works of Dalgarno, which had become exceedingly rare, have been lately reprinted by the Maitland Club.
