Notes
Henry Grandjean was one of the first to enter the South American Market. He was also one of the first to manufacture marine chronometers in Switzerland, and was an initiator of the Neuchâtel Observatory. Grandjean received a First Class medal at the 1851 Universal Exposition in London. In 1868 the company won an award for its marine chronometers. Henry died in 1879 but it appears that the company continued until 1899.
