Johann Konrad Ammann

Johann Konrad Amman (1669 – 1724) was a Swiss physician and instructor of non-verbal deaf persons.

Not to be confused with Johann Conrad Amman (1724–1811) or Johann Amman.

J.C. Amman

Johann Konrad Amman was born at Schaffhausen, Switzerland. After graduating at Basel in 1687 he began to practise at Amsterdam, where he gained a great reputation. He was one of the earliest writers on the instruction of the non-verbal deaf, and first called attention to his method in his Surdus loquens (Amsterdam, 1692), which was often reprinted, and was reproduced by John Wallis in the Philosophical Transactions (1698).

His process consisted principally in exciting the attention of his pupils to the motions of his lips and larynx while he spoke, and then inducing them to imitate these movements, until he brought them to repeat distinctly letters, syllables and words. He died at Warmond, near Leiden.
