Carl Myers (1842-1925) was a meteorologist, photographer and balloonist. In 1875, Myers and his wife Mary ("Carlotta, Queen of the Air") began experimenting with balloons and made their first ascensions in 1880. Myers constructed and flew a variety of balloons and airships, and worked on the following technical advances: he developed a varnishing machine for producing fabrics impervious to hydrogen gas; he produced a portable system for generating hydrogen gas; he patented an apparatus for guiding balloons; and he made the first balloon ascension using natural gas as the lifting medium. Myers manufactured balloons for the U.S. Weather Bureau's rainmaking experiments and also supplied the United States Army Signal Corps (USASC) with twenty-one balloons for use in Spanish American War. Myers retired in 1910. The collection consists of 91 images of the following: balloons, airships, and aeronautical gear in various stages of construction and flight; interior and exterior views of the Carl Myers Balloon Farm; and a number of portraits taken of the family and visitors, including Thomas C. Benbow, a noted pioneering aeronaut. It also contains correspondence written by Myers to Professor Henry Allen (H.A.)
