AMMAN, Johann Conrad, a physician, and one of the earliest writers on the instruction of the deaf and dumb, was born at Schaffhausen, in Switzerland, in 1669. In 1687 he graduated at Basle, and commenced the practice of his profession at Amsterdam, to which he had to flee on account of his religious views. He first called the attention of the public to his method of training the deaf and dumb in a paper which was inserted in the Philosophical Transactions, and which appeared in a separate form in the year 1692, under the title Surdus Loquens. It was again issued, with much additional matter, in 1702 and 1728, under the title Dissertatio de Loquela. In this work, which Haller terms a vere aureum, ” he develops, with great ability, the mechanism of vocal utterance, and describes the process which he employed in teaching its use. This consisted principally in exciting the attention of his pupils to the motions of his lips and larynx while he spoke, and then inducing them by gentle means to imitate these movements, till he brought them to repeat distinctly letters, syllables, and words. As his method was excellent, we may readily give him credit for the all but universal success to which he laid claim. The edition of Caelius Aurelianus, which was undertaken by the Wet-steins in 1709, and still ranks as one of the best editions of that author, was superintended by Amman. He died about 1730....
AMMAN, Josτ, an artist celebrated chiefly for his engravings on wood, was born at Zurich in June 1539. Of his personal history little is known beyond the fact that he removed in 1560 to Nuremberg, where he continued to reside until his death in March 1591. His productiveness was very remarkable, as may be gathered from the statement of one of his pupils, that the drawings he made during a period of four years would have filled a haywaggon. A large number of his original drawings are contained in the Berlin collection of engravings. The genuineness of not a few of the specimens to be seen elsewhere is at least questionable. A series of copperplate engravings by Amman of the kings of France, with short biographies, appeared at Frankfort in 1576. He also executed many of the woodcut illustrations for the Bible published at Frankfort by Feierabend. Another serial work, the Panoplia Omnium Liberalium Mechanicarum et Sedentariarum Artium Genera Continens, containing 115 plates, is of great value. Amman’s drawing is correct and spirited, and his delineation of the details of costume, &c., is minute and accurate. He executed too much, however, to permit of his reaching the highest style of art. Paintings in oil and on glass are attributed ’ to him, but no specimen of these is known to exist,
AMMAN, Paul, a physician and botanist, w as born at Breslau on the 30th August 1634. In 1662 he received the degree of doctor of physic from the university of Leipsic, and in 1664 was admitted a member of the society Naturoe Curiosorum, under the name of Dr y ander. Shortly afterwards he was chosen extraordinary professor of medicine in the above-mentioned university; and in 1674 he was promoted to the botanical chair, which he again in 1682 exchanged for the physiological. He died on the 4th February 1691. Paul Amman seems to have been a man of acute mind and extensive learning; but a restless and irritable disposition led him to engage too much in controversy, and to indulge in raillery in his writings to a degree λvhich the nature of the subjects hardly warranted.
Amman’s principal works were— Medicina Critica, seu Centuria Casuum, in Facultate Lipsiensi resolutorum, variis Discursibus aucta; Paraenesis ad Docentes occupata circa Institutionum, Medicarum Emendationem; Irenicum Numae Pompilii cum, Hippocrate; Supellea> Botanica, et Manuductio ad Materiam, Medicam,; and. Character Naturalis Plantarum.

AMMANATI, Bartolomeo, a celebrated Florentino architect and sculptor, was born in 1511, and died in 1592. He studied under Bandinelli and Sansovius, and closely imitated the style of Michael Angelo. He was more distinguished in architecture than in sculpture. He designed many buildings in Rome, Lucca, and Florence, an addition to the Pitti palace in the last-named city being one of his most celebrated works. He also planned the beautiful bridge over the Arno, known as Ponte della Trinita— one of his celebrated works. The three arches are elliptic, and though very light and elegant, have resisted the fury of the river, which has swept away several other bridges at different times. Ammanati’s wife, daughter of Giov. Antonio Battiferri, an elegant and accomplished woman, published a volume of poems of considerable merit.
