Edouard Durussel (1842-1888) apprenticed in Switzerland but was trained at the Royal Mint, London, for three years; recommended by Antoine Bovy, he was employed as an engraver in Paris from 1865-67, after which he married in London and again worked as an engraver. In 1869, he settled in Berne and set up a die-sinking business, principally producing medals from 1876-88. This pattern for the gold 20 francs was one of his finest pieces, which he himself described as portraying a symbolic image of Liberty. All of his patterns are very rare, this one especially so; the dies were destroyed in 1890, shortly after Durussel's death.
