Steward Aneroid Barometer

<< >>
Description
This is a pocket aneroid barometer, 2 inches diameter. The face reads: “COMPENSATED / TEMP ALT. SCALE / 50° FAHT / J. H. STEWARD LTD / 406, STRAND / 457, WEST STRAND / LONDON / 6191.” The circumference of the face is graduated for altitude, from -10 to +1500 feet. An inner circle is graduated from 17.5 to 31 inches of mercury. A paper label in the lid of the leather case provides a correction to be applied to the altitude scale for mean air temperature above or below 50° Fahrenheit.
James Henry Steward opened an optical instrument shop at 406 Strand in 1857, a second shop at 457 West Strand in 1886, and a third shop at 7 Gracechurch St. in 1893. While Steward sold this instrument, he probably did not make it.
This was used by the Washington born intaglio artist Benson Bond Moore. The Archives of American Art transferred it to the National Museum of American History.
