On November 13, 1745, Valentin Haüy was born in France, a well-known teacher who founded several schools and enterprises for the blind in Paris and St. Petersburg. According to the decision of the World Health Organization (WHO), this date became the basis for the establishment of the International Day of the Blind, the main goal of which is to draw the attention of the general public to those who have permanently lost their sight and found themselves in a difficult life situation.
Until the 18th century, the world did not know educational institutions for the blind. Valentin Gayuy first demonstrated his method of teaching the blind, using a typeface he invented. In 1784, in Paris, without the support of the government and charitable societies, at his own expense in his own house, he opened the world's first school for blind children called the Workshop of the Working Blind. The first student of Valentin Gayuy was the boy Francois de Lesueur, picked up on the church porch. Then 11 more of his homeless peers entered the school.
The education and upbringing of blind children was put on a scientific basis by Valentin Hayuy. He developed the relief-linear type "uncial". This typeface takes its name from a Latin word meaning "equal in length to one ounce". These were large, even letters, embossed in relief on thick paper. The main advantage of "uncial" was that with the help of this font it was possible to teach blind children to read and print books for the blind.
