# Umirzak Sultangazin

Umirzak Makhmutovich Sultangazin (4 October 1936, Karaoba, Sarykol District, Kostanay Region, Kazakh SSR, USSR — 23 May 2005, Berlin, Germany) was a scientist, mathematician, Doctor of Physical and Mathematical Sciences (1972), Professor (1974), Academician at the Kazakh SSR Academy of Sciences (1983), and an honorary member of the Russian Academy of Cosmonautics.

## Biography

Umirzak Sultangazin was born in the settlement of Karaoba (Sarykol District, Kostanay Region, Kazakh SSR) on 4 October 1936. After graduation from Kazakh State University in 1958 with a degree in Mathematics, Sultangazin successfully lectured until 1978 (as assistant, senior lecturer, associate professor and Computational Mathematics Chair).
In 1964 he moved to Novosibirsk to work at the Siberian Branch of the USSR Academy of Sciences, where he defended his Ph.D. thesis at the Institute of Mathematics on The splitting method for the kinetic equation of transfer. Together with Gury Marchuk, he proved the feasibility of using the splitting method for the radiative transfer equations and proved their convergence in this case. In 1968 he was hired as a senior researcher at the Computing Center of the Siberian Branch of the USSR Academy of Sciences in Novosibirsk, where he defended his doctoral dissertation on "The method of spherical harmonics for the non-stationary kinetic equation of radiation transfer" (in the field of Differential Equations) based on the results of his research. He became a Doctor of Sciences at the age of 36.
In 1978, Umirzak Sultangazin was invited to head the Institute of Mathematics and Mechanics at the Academy of Sciences of the Kazakh SSR, where he trained numerous young mathematicians. He became the President of Kazakhstan’s Academy of Sciences in 1988 and held this position until February 1994. Three regional branches of the Academy were established in the cities of Shymkent, Ust’-Kamenogorsk and Atyrau under his leadership.
On 26 March 1989 he was elected People's Deputy of the USSR by the scientists of the Academy of Sciences of the Kazakh SSR to represent the Karaganda-Oktyabrsk national-territorial electoral district No. 142 of the Kazakh SSR.
Sultangazin ran the Institute of Space Research at Kazakhstan Academy of Sciences from its establishment in 1991 (pursuant to Umirzak’s own proposal) until his death in 2005, spurring the growth of Kazakhstan’s space industry.
In 2004, Sultangazin led the implementation of the scientific and technical program titled National Space Monitoring System of the Republic of Kazakhstan. After his personal meetings with President Nazarbayev, the state program for the development of the space industry in Kazakhstan was launched.
On 23 May 2005, Umirzak Sultangazin, aged 68, passed away in a Berlin clinic after a serious illness.
