Georges Bontemps

Georges Bontemps was a director of an eminent French glass manufacturer in the 19th century, moved to England to work and is accredited with the re-invention of a technique for making ruby-coloured glass that was first used by the Venetians in the 16th century. He was a jury member at the 1862 International Exhibition in London and the Exposition Universelle (1867) in Paris. Provided by Wikipedia
