Lansdowne. It has a limestone foundation and a hipped roof of standing seam metal.","why_significant":"The house is significant as the birthplace and boyhood home of Zachary Lansdowne, a figure in the development of rigid lighter-than-airships for the U.S. Navy in the 1920s. He commanded the airship Shenandoah, which broke apart in a thunderstorm over Noble County, Ohio, in September 1925. The house is also valued locally as the home of an early 20th century military hero.","narrative":"Built about 1870 for James M. Lansdowne, this simple two-story frame house at 338 East Third Street in Greenville sits on a limestone foundation under a hipped metal roof. Tall, narrow windows and a bracketed cornice with a paneled frieze are its main features. Later changes include synthetic shingle siding, solid shutters in place of louvred ones, and removal of the right half of the turn-of-the-century porch. The house matters because of Zachary Lansdowne, born there on December 1, 1888. He became a Navy officer and a pioneer of rigid lighter-than-air ships, served as liaison with the Zeppelin Works in Berlin, and wrote an airship operation manual later adopted by the Navy. As commander of the airship Shenandoah, he circled Greenville in 1924 to speak with his mother by radio. He died in the ship's crash over Ohio in September 1925. The house remains a local link to that aviation and military history.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Listed as a private residence in good condition, altered, and occupied.
