1669–1724
A Swiss physician working in Amsterdam, he became one of the early figures in teaching deaf people through speech and lipreading. His books on voice, articulation, and deaf education helped shape later European approaches to instruction.

by Johann Conrad Amman
Born in Schaffhausen in 1669, Johann Conrad Amman studied at Basel and later built a strong medical reputation in Amsterdam. Alongside his medical work, he became known for teaching deaf pupils and for writing about how speech is formed.
Amman is remembered as one of the earliest authors to describe methods for teaching deaf people to speak through careful attention to breathing, articulation, and lipreading. His works, including Surdus Loquens and Dissertatio de Loquela, were influential in the history of deaf education and speech study.
Although some of his ideas belong firmly to his era, his writing had a lasting impact on later teachers and scholars across Europe. He died in 1724, but his name remains closely linked with the early development of speech training for deaf learners.
