|Thaddeus Lowe's Balloon Ascent, May 31, 1862, |
Smithsonian Institution Archives, SIA2011-0961.
The launch, a culmination of failure and determination, was watched by first Smithsonian Secretary Joseph Henry. Lowe’s test launches helped demonstrate the effectiveness of his hot air balloon reconnaissance for the North during the Civil War. From the basket, Lowe could use a telegraph to communicate troop movements to the ground.
Henry, who advised Lowe on his work, encouraged the Union Army to establish a balloon corps within the army. During the war, the balloon corps conducted reconnaissance which included tracking Confederate troop movements and reporting on Confederate artillery, among other valuable information.
