The Kovako Braillewriter, a braille typewriter for the blind, was invented by Lieutenant Colonel Alexander M. Kovako of St. Petersburg, Russia. Kovako produced two models. The first was the Tiphlotype, which he exhibited in 1885 at the Amsterdam Exhibition for the Blind. Ultimately, it did not function well so this later, improved model was introduced. It was named the Stigmatype (ститматипъ), (sometimes referred to as the Stigmatique) and it sold for 80 Francs.
