JOHN BULWER (fl. 1654) Chirologia; or, The Natvrall
Langvage of the Hand. London, Tho. Harper, 1644.
 A work
dealing with communication by sign language and gesture, Chirologia won for its
author the appellation "Chirosopher." The work's chief concern is the
various ways in which the hand can be used to express both words and
abstract concepts. Bulwer maintained that signs are the natural language
of the all persons, not just of the deaf. An early pioneer in the
education of the deaf, Bulwer was the first to propose an "academy of the
mute." He developed the technique of lip-reading, first proposed in his
Philocophus; or, The Deafe and Dumbe Man's Friend (London, 1648),
and brought attention to the capacity to enjoy music through the medium
of the teeth. Bulwer knew of the manual alphabet, but makes no
suggestions with regard to speaking on the fingers. His work evidences
the strong influence of Juan Pablo Bonet (1579-1633), whose Reduction
de las Letras y Arte para Enseñar a Ablar los Mudos (Madrid,
1620) advocated training the student in speech through the reduction of
letters of the alphabet to their phonetic value. (Galland p. 31; Guyot

DENIS DIDEROT (1713-1784) Lettre sur les Sourds et Muets [et
Lettre sur les Aveugles] Amsterdam, 1772. Best known
for his
Encyclopédie (Paris, 1751-72) in these two essays Diderot
seeks to show the dependence of man's ideas upon the five senses, and the
way in which the intellect is affected when deprived of one of them.
Philosophically, the two pieces are important in that they expound an
early form of the principle of the relativity of knowledge. Lettre sur
les Sourds et Muets first appeared in 1751. Addressing the problem of
the origin, nature, and aesthetic value of language, Diderot maintains
that French has certain advantages over Greek and Latin. Within this
context he considers the effect of deaf-mutism. He first brought out
Lettre sure les Aveugles in 1749. In it he presents a theory of
survival by superior adaptation. As an example of adaptation, he
maintains that the blind might be taught to read through the sense of
touch. The two essays appear together in this edition, although the title
page lists only the Lettre sur les Sourds et Muets. (Guyot p. 42;

JAMES HATLEY FRERE (1779-1866) The Gospel According to Saint
Matthew. [London, Printed for the Blackhearth Society for Embossing
the Scriptures for the Blind by Barritt and Co., 1841] Known
also
as a Biblical exegete, Frere about 1838 introduced a phonetic system for
enabling the blind to read. To reduce the bulk of embossed books, Frere
based his system upon shorthand rather than the standard alphabet. His
system consists of raised characters, including straight lines, whole and
half circles, hooked lines, and angles, set in return lines; that is,
lines reading alterately from left to right and right to left. Frere
devised a cheap method for stereotyping his books, employing copper wires
formed in the shape of his characters and soldered on the embossing
plate. Saint Matthew is part of a nine-volume series of the New
Testament embossed in Frere's system. During his lifetime, he was also
able to have printed the Book of Isaiah (London, 1843-1849). His
system was not widely adopted because it was found to have adverse
effects upon pronunciation. This copy of Saint Matthew includes a
short pamphlet by Frere explaining how to teach his system.
SEBASTIEN GUILLIE (1780-1865) Notice Historique sur
l'Instruction
des Jeunes Aveugles. Paris, Imprimé par les Jeunes Aveugles,
1819. Guillie is the author of several works on the eye,
and on
education of the blind. Notice is a rare work, printed with script
letters in bold relief on light cardboard sheets, a technique invented by
Valentin Haüy (1745-1822). It includes a history of the Institution
Royale des Jeunes Aveugles de Paris, founded in 1784, of which Guillie
was director. A second section gives details on the manner of making
books in relief, and on teaching reading in relief. Notice is
essentially a revision of the first two chapters of part three of
Guillie's Essai sur l'Instruction des Aveugles (Paris, 1817). (BMC

CHARLES MICHEL DE L'EPEE (1712-1789) Institution des Sourds et
Muets. Paris, Nyone l'Aine, 1776.
Lawyer and priest, L'Epée turned his attention to the instruction of the deaf upon
being deprived of his priestly functions because of Jansenist sympathies.
In 1755 he founded his own school for teaching the deaf, which in 1791
became the Insitution Nationale des Sourds-Muets à Paris by action
of the National Assembly. In Institution des Sourds ed Muets, first
published in 1774, L'Epée puts forth his theories on teaching the
deaf to communicate by signs, a method which he was the first to fully
develop. He emphasizes the importance of having the pupil master signs
and writing before advancing to lip-reading and articulation.
L'Epée was much influenced by Joan Pablo Bonet's advocacy of
teaching a manual alphabet to the student, and by the Dissertatio de
Loquela (Amsterdam, 1700) of Jan Coenrad Amman, on the production of
vocal sounds. Opposition to his methods came chiefly from Giacobbo
Rodriguez Pereira (1715-1780). (BMC 111:738; Bibliothèque
Nationale XCV:186; Stojan 537)
WILLIAM MOON (1818-1894) The Three Epistles of Saint John,
Embossed for the Blind on Moon's Improved System. Brighton [Eng.] Printed at
W. Moon's Establishment for English and Foreign Books and Maps for the
Blind, 1856.
 After becoming blind in
1840, William Moon taught
himself to read by the aid of the various embossed systems then in use,
and became convince that none was really suited to the purpose. Aged
persons experienced difficulty in reading by touch, and the complexities
of stenographic systems made them hard to leard. Basing his efforts on
the work of James Hatley Frere (1779-1866), Moon in 1847 brought out a
system using only nine basic characters, placed in various positions to
represent the letters of the alphabet. In many instances, it is still in
use today along with that developed by Louis Braille (1809-1852) just
thirteen years earlier. Many works, both sacred and secular, were brought
out in embossed type using Moon's system during his lifetime. Epistles
of Saint John was taken from a larger series of the complete New
Testament. It appears to be a unique copy, prepared especially for Georg
V (1819-1878), the last king of Hanover, who was blind.
ROCH AMBROISE CUCURRON SICARD (1742-1822) Théorie des
Signes pour l'Instruction des Sourds-Muets. Paris, Imprimerie de
l'Instruction des Sourds-Muets, 1808. 2 vols. Originally
director
of the school for deaf-mutes at Bordeaux, the Abbé Sicard
succeeded Charles Michel de L'Epée at Paris upon the latter's
death in 1789. This is the first edition of Théorie des
Signes, in which Sicard adopts and develops L'Epée's views on
signs as the natural language of the deaf, giving the reader extensive
descriptions of various signs used by the deaf for both concrete objects,
abstract concepts, and grammatical relations. Appended to volume two is a
short essay by Sicard on Jean Massieu, one of several pupils to whom the
Abbé addressed question at public lectures, held in London, to
demonstrate his methods over against the oral method of teaching speech
then common in England. The Abbé Sicard's methods may also be
examined in his Cours d'Instruction d'un Sourd-Muet de Naissance
(Paris, 1800). (Bibliothéque Nationale CLXXII: 334; Guyot p. 14;
Stojan 542)
