The doctorate certificate that Albert Einstein obtained from the University of Zurich in 1906 will come up for auction in June, auctioneers Fischer Galerie said on Friday.
An honorary doctorate certificate awarded to the physicist by the University of Geneva in 1909 will also come under the hammer, the Lucerne-based auctioneer said.
Einstein, who revolutionised physics, was awarded the doctorate of philosophy by the University of Zurich's mathematics and natural sciences department after finishing his doctoral thesis titled "A new determination of molecular dimensions" which explains how the size of atoms could be determined.
During the same year, he came up with the formula for which he is best known -- e=mc2.
Three years later, the University of Geneva awarded him a honorary doctorate in physical sciences, noting that he had become "well worthy" of it.
He was in Bern in 1905 when he wrote the articles that formed the basis of his relativity theory of motion,.
Einstein was born in Germany in 1879 and died in the United States in 1955.
The auction would be held June 10 to 12, with a viewing scheduled between May 30 and June 7.
