"Observations of a Deaf and Mute on the Elementary Course of Education for the Deaf and Dumb, Published in 1779 by Abbé Deschamps, Chaplain of the Church of Orléans" is a valuable document that reflects the thoughts and impressions of the deaf and dumb author Pierre Deslauges regarding the educational process among the hearing impaired and speech. In his book, the author shares his observations and reflections on the shortcomings and advantages of the deaf and dumb education system in his time. The work provides a unique opportunity to better understand the needs and capabilities of people with such individual characteristics as deafness and muteness. Written with care and a sense of sympathy for the heroes, the book "Observation of a deaf and dumb person on the initial course of education of the deaf and dumb" remains relevant and informative to this day.
