Yulii Borisovich Khariton (27 February 1904 – 19 December 1996) was a Russian physicist credited as a leading scientist in the Soviet Union's nuclear weapons program. Since the initiation of the atomic bomb project by Joseph Stalin in 1943, Khariton was the "chief Nuclear weapon designer" and remained associated with the Soviet program for nearly four decades. In honour of the centennial of his birthday in 2004, his image appeared on a Russian postal stamp by the Russian government.
Family, early life and education
Yulii Borisovich Khariton was born in Saint Petersburg, Russian Empire to an ethnic middle class Russian Jewish family, on 27 February 1904.:xii His father, Boris Osipovich Khariton, was a political journalist, an editor, and a publisher, who had attained a law degree from Kiev University in Ukraine.:xlii:xii His father worked for the newspaper Rech, the main organ of the Constitutional Democratic Party, and was a well known figure in the political circles of Russia. After the Russian revolution dismantled the Tsarist autocracy in 1917, Boris Khariton had clashes with the Bolsheviks as he was at odds with Vladimir Lenin's Soviet ideology.:xlii His father was exiled to Baltic states from Russia in 1922 at the age of forty six along with professors and journalists on one of the so-called Philosophers' ships, subsequently working for an emigrant newspaper in Latvia.
His father, Boris Khariton, remained there until Latvia's annexation by the Soviet Union in 1940 and, at the age of sixty-four, was then arrested by the NKVD and sentenced to seven years of work labour in a Gulag where he died.:xlii
Yulii's mother, Mirra Yakovlevna Burovskaya, was a theatre actress who performed at the Moscow Art Theatre. She left Russia in 1910 due to an illness that had to be treated at the European resort.:xlii Yulii was six years old when his mother left him and was taken care by an Estonian woman, hired by his father while in exile in Latvia.:134 Yulii's mother never returned to Russia and divorced his father, only to marry her psychiatrist, Dr. Max Eitingon.:xli
Yulii was home schooled by his Estonian housekeeper, hired by his father, who taught him German language.:xliii At the age of eleven, he began attending regular school.:xliii In Saint Petersburg, he went to attend a trade school which he completed at the age of fifteen and found work at a local mechanical workshop where he learned how to operate various machinery as a machinist.:xlii
In 1920, he enrolled in the Leningrad Polytechnical Institute to study the mechanical engineering but later chose to study physics, which he found to be more stimulating.:xliii He studied physics under Russian physicists, Abram Ioffe, Nikolay Semyonov, and Alexander Friedmann. Khariton was particularly fascinated with the work of Semenov whose research used the techniques of physics in chemistry, which Semenov called "chemical physics.".:xliii Khariton's talent was recognised by Semenov who supported his research project in investigations of the light-emitting ability of phosphorus combined with oxygen, and reported the results in both German and Russian languages.:xliv In 1926, Khariton completed his degree in physics from the Leningrad Polytechnical Institute and ended his research project as he prepared for his first foreign trip to England. :xlv
Before departing, he was introduced to Pyotr Kapitsa by Semenov who asked the latter to help Yulii secure a fellowship at the Cavendish Laboratory in England. In England, Khariton attended the University of Cambridge to do his doctoral in physics under Ernest Rutherford in 1926.:xlv At Cambridge, he worked with James Chadwick on investigating the sensitivity of the eye with respect to weak light impulses and alpha radiation. Khariton earned his PhD in 1928 from Cambridge University.:xlv
Soviet atomic bomb project
In 1928, Khariton decided to take up the residence in (Germany) to be near his mother, but was appalled and frightened by the political propaganda of the Nazi Party in Germany; therefore returning to Soviet Union while his mother left for Palestine.:xlv
In 1931, he joined the Institute of Chemical Physics and eventually headed the explosion laboratory until 1946, working closely with another Russian physicist Yakov Borisovich Zel'dovich, on exothermic chemical chain reactions..:xlvi
In 1935, he received his doctorate in physical and mathematical sciences. During this period, Khariton and Zel'dovich conducted experiments regarding chain reactions of uranium. He was elected as a corresponding member of the USSR Academy of Sciences in 1946, and as a full member in 1953.
He received the following honours:
- Three times Hero of Socialist Labor (1949, 1951, 1954)
- Six Orders of Lenin (1949, 1956, 1962, 1964, 1974, 1984)
- Order of the October Revolution (1971)
- Order of the Red Banner of Labor (1945)
- Order of the Red Star (1944)
