Five Francs 1979 Albert Einstein - Portrait, Coin from Switzerland - detailed information

The Five Francs coin is a circulating denomination of the Swiss Franc. Given that Switzerland has four official languages, the Franc has three different names: Franken in German, franc in French and Romansh, and franco in Italian. Initially when federal Swiss coinage was introduced in 1850, all "francs" (including the half franc) were full-bodied silver, while the centimes were either billon (low-grade silver) or base metal.

Normal circulating coins went through several transformations: with a seated figure of Helvetia on the obverse, then a portrait of Helvetia, then the current design by Paul Burkhard. The earliest coins were issued with the specifications of the Latin Monetary Union until in 1931 when the coins were made smaller and the content was slightly debased. Starting in 1936, the country also occasionally issued circulating commemorative one-year type 5 Franc coins in silver to mark various important occasions.

After these were demonetised in 1971 and the denomination became copper-nickel (CuproNickel), Swissimint issued an extensive series of commemoratives between 1974 and 1990 (in parallel with the regular design), after which time it stopped issuing commemoratives in this denomination and returned to the regular design only.

This 1979 Five Francs commemorative coin celebrates the 100th anniversary of the birth of Albert Einstein. It is the first of two coins issued for the occasion and features his portrait; the second 5 Fr. coin features his famous formula for mass/energy equivalence E=mc2.

Albert Einstein (1879 - 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). His work is also known for its influence on the philosophy of science. He is best known to the general public for his mass-energy equivalence formula E = mc2, which has been called "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory.

The son of a salesman who later operated an electrochemical factory, Einstein was born in the German Empire but moved to Switzerland in 1895 and renounced his German citizenship in 1896. Specialising in physics and mathematics, he received his academic teaching diploma from the Swiss Federal Polytechnic School (German: eidgenössische polytechnische Schule, later ETH) in Zürich in 1900. The following year, he acquired Swiss citizenship, which he kept for his entire life.

5 Fr. coins issued in 1979 have now been in circulation for 45 years.
