Lowe’s Barometer, Udvar-Hazy Center, National Air and Space Museum
A barometer and case used by aeronaut Thaddeus S.C. Lowe during the Civil War is on display at the Boeing Aviation Hangar at the Steven F. Udvar-Hazy Center. “Barometers and thermometers tended to be very tall,” explains senior curator Tom Crouch. Back then, these instruments “used mercury and [had] to have enough mercury to accurately measure the pressure.” Udvar-Hazy also boasts a pair of Lowe’s binoculars and a wooden valve assembly from The Great Western balloon, constructed by Lowe in 1859.
