Solomon Andrews (inventor)

Solomon was born on February 15, 1806, in Herkimer, New York to Josiah Bishop Andrews and Mary Bissell. Solomon Andrew's daughter, Harriet Cornelia Andrews, married Frederick S. Hilton on June 15, 1858. Later in his life in 1863, Solomon's airship, Aereon, would fly for the first time. He would also live to see his second one fly too in 1866. Solomon Andrews died on October 17, 1872, in Perth Amboy, New Jersey. His widow died in 1881. ==Airships==

The difference of specific gravity between the balloon and the surrounding atmosphere could be converted by a system of inclined planes to steer the craft without a motor. He referred to his propulsion as "gravitation." The craft was not normally trimmed to be neutrally buoyant. Instead it would be cycled between positive and negative buoyancy. The resulting airflow across the body of the craft and attached airfoils would propel it. His first "Aereon" flew over Perth Amboy on June 1, 1863. This had three 80-foot cigar-shaped balloons, with a rudder and gondola. Buoyancy was controlled by jettisoning sand ballast or releasing hydrogen lift gas. and ended at Oyster Bay, Long Island. Andrews's airship company ultimately failed due in part to a nationwide economic recession and associated bank failures immediately after the war, and he never flew again. ==Other inventions==

Andrews also invented a sewing machine, a barrel making machine, fumigators, forging presses, a kitchen range, a gas lamp, a nicotine-filtering pipe, rekeying and a padlock which has been used by the U.S. Post Office since 1842. ==Legacy==

The Aereon Corporation attempted, in New Jersey in 1969, to replicate and improve on the airship designs of Solomon Andrews. This was written about in the book "The Deltoid Pumpkin Seed," by John McPhee (). This book and Andrews' work provided the inspiration for development of the Hyperblimp, and various embodiments of an underwater gliding toy, by inventor Daniel Geery. == Notes ==
