Object Details
- Description
- This pamphlet describes and illustrates the operation of a pantograph designed by L. Blondeau, a geographical draftsman employed by the Bureau des Cartes et Plans of the French Ministry of War. According to the instructions, the instrument was manufactured by Molteni & Cie., opticians and manufacturers, which had the address 13 Boulevard St. Denis in Paris. L. Blondeau took out his French patent for a pantograph in 1841, the same year that the firm Molteni & Cie. was established. Molteni & Cie. was at the address 13 Boulevard Saint-Denis in 1844, but by 1854 had moved to another address. This dates the instructions to the period 1841-1853.
