Deng Jiaxian was a Chinese physicist, known as the Father of China's Atomic Bomb（原子弹）. Born in Anhui Province, Deng attended the National Southwestern Associated University in 1941 and went to America for a further study in physics. He studied a lot and got much useful knowledge.

After Deng's graduation, he didn't accept the high-paid positions and superb research conditions provided by the American government or universities. Instead, he returned to Beijing in 1950 to work on nuclear research（核能研究）.

Deng faced great difficulties at that time because there was no such research information to learn from and few scientists. He worked with a group of recent college graduates and used abacuses for calculation. It took about a month to finish a stage of calculation and about a year to calculate it nine times.

For about eight years Deng worked very hard at the Gobi Desert nuclear testing site in northwest China.

In October 1964, under Deng's leadership, China successfully tested its first atomic bomb. In June 1967, China's first hydrogen bomb test was also carried out successfully. In 1979, a parachute failure happened during one experiment, which caused an atomic bomb to crash to the ground but it did not set off. Deng knew the danger in cleaning up the crashed bomb. "You are young; you can't go to do this, " Deng said to his colleagues. So he picked up the broken pieces of the bomb himself instead of sending his team.

Deng's wife, a doctor, learned that Deng had touched the broken pieces of the atomic bomb, and ordered him to return to Beijing for a full body checking. The results showed that he had been badly hurt by deadly nuclear radiation（辐射）. However, he still chose to return to the test site and continued to solve the problem himself.

In 1986, at age 62, Deng passed away because of the radiation. As a national hero, he was awarded the Two Bombs and One Satellite Merit Medal in 1999.
