Ri Sung Gi, World- Famous Korean Chemist
Pyongyang, May 11 (KCNA) -- Ri Sung Gi (1905-1996) was a Korean chemist who had become world-famous for inventing vinalon fibre.

He studied at a university in an alien land because of the Japanese colonial rule over Korea.

In Juche 28 (1939), he succeeded in making an invention of a synthetic fiber, called vinalon, from polyvinyl alcohol for the first time in the world and started research into its mass-production.

After the liberation of Korea, he took pains for development of national education and science in south Korea, but failed to materialize his desire.

He came to the northern half of Korea during the Fatherland Liberation War (1950-1953). Thanks to the deep care of President Kim Il Sung, Ri could continue to make the researches even in the wartime, laying scientific foundations for vinalon industry.

His efforts led to the creation of a large-scale vinalon industry relied on limestone and anthracite abundant in the country.

Later, he gained successes in improving its quality, increasing its variety and producing movilon fibre.

An academician, professor and doctor, he brought up a number of scientists and wrote many books.

He was also awarded titles of honorary academician and professor from abroad.

His book "Vinalon" was translated and published in many countries.

He, a deputy to the DPRK Supreme People's Assembly, was awarded many orders and medals, including Title of Labor Hero, Kim Il Sung Prize, Title of People's Scientist and Order of National Flag 1st Class, for his signal contribution to the nation's sci-tech development.
