Oleg Tretiakoff

Parcours

Oleg Tretiakoff, diplômé de l'X (École polytechnique) et de SUPAERO (Institut supérieur de l'aéronautique et de l'espace), a commencé sa carrière au CEA (Commissariat à l'énergie atomique), à Saclay dans le service de Jules Horowitz, puis à Cadarache en tant que Chef du service des réacteurs nucléaires à neutrons rapides.
Après avoir inventé la première cellule braille piézoélectrique et construit le prototype du premier appareil à caractères Braille réactualisables, la digicassette* , Oleg Tretiakoff quitte le CEA en 1981.
Oleg Tretiakoff travaillera notamment avec Deane Blazie et la NSF (US National Science Foundation).

Quelques déclarations...

From

American Printing House for the Blind

"Blindness History Basics: A Brief History of the Refreshable Braille Display"

"The real breakthrough occurred when Oleg and Andie Tretiakoff introduced the first commercially available paperless braille machine in 1976 in Paris, France."
"For much of the last fifty years, refreshable braille development has simply been a refinement of Tretiakoff’s ideas."
"There are many refreshable braille devices on the market from many manufacturers, but until recently, all continued to rely on variations of Tretiakoffs piezo-electric cell."
From

Museum of the American Printing House for the Blind

"Elinfa Digicassette and adapter"

"Developed by Oleg Tretiakoff 1975-1977, the Digicassette combined a piezoelectric reed style braille display with a cassette tape storage system. See U.S. Patent 4044350."
"Piezoelectric cells became the dominant braille display technology over the next decade. Tretiakoff went on to work for Humanware."
From

American Council of the Blind

"Is There a New Optacon in Your Future?"

"According to Oleg Tretiakoff, who developed the first piezo-electric braille display in 1975, a new, improved Optacon is on the near horizon."
From

Museum of the American Printing House for the Blind

"VersaBraille System"

"Versabraille was inspired by the Elinfa Digicassette invented by Oleg Tretiakoff in France 1975-1977."
From

American Foundation for the Blind

"An Oral History Interview with Deane Blazie"

"Oleg designed the very first braille cell, based on piezo-electric crystals."
From

National Federation of the Blind

"Refreshable Braille Now and in the Years Ahead by Deane Blazie"

"Then in the late '70's Oleg Tretiakoff introduced the first Piezoelectric display.He eventually put it in a device, and it was sold around the country. Does anyone remember the name of that device? The company was Elinfa, and the device was the Digi-cassette."
"That's the truth. Oleg invented the first one and he tried to market it to TeleSensory but decided they could do their own, and in the early eighties TeleSensory introduced the VersaBraille with their own display based on Oleg's Piezo design."
