In 1898, he graduated from Alexandrovski Lyceum in Saint Petersburg and the same year started his career at the Ministry of Foreign Affairs.
In 1917, after October Revolution in Russia, Lev Urusov emigrated to France and lived there until his death in 1933.
He retained this position even after the revolution and remained the only official representative of Russia in the IOC in the years since.
After the end of the World War he repeatedly submitted proposals for incorporating Russian teams back into the Olympic movement.
[1] The rejection was based on the fact that Soviet Russia has not been recognized yet by the IOC while the emigrants were not representing a distinct existing country.
