Emil Grigoryevich Gilels[a] (19 October 1916 – 14 October 1985) was a Russian pianist. He is widely regarded as one of the greatest pianists of all time.

Following his activities in Brussels, a scheduled tour and American debut at the 1939 New York World’s Fair was aborted because of the outbreak of the Second World War. Sergei Rachmaninoff, living in exile from Russia, had heard of the reputation of Gilels, and began to listen to Gilels’ radio performances. Rachmaninoff subsequently regarded Gilels as his pianistic successor, and sent him his medal and diploma. This medal, engraved with the profile of Anton Rubinstein, and the diploma were once presented to Rachmaninoff to symbolize his succession from Rubinstein, and Rachmaninoff himself added Gilels’ name to the document. Gilels treasured these relics all his life.
