notes: label: Description
content: Georges Ernest Fleuriais (1840-1895), a French naval officer, designed this type of gyroscopic artificial horizon, for use when the natural horizon could not be seen. This example was probably acquired for the Smithsonian by Samuel Pierpont Langley, the third Secretary of the Institution. The “A. Hurlimann à Paris” inscription is that of Alfred Hurlimann, a French instrument maker who showed examples at the Paris Exposition Universelle of 1889. An invoice in the Smithsonian Institution Archives indicates that it cost $200 (plus $8 for packing).
