This was a shipbuilding company with shipyards in Pittsburgh and Wilmington, Delaware. It was founded in 1891 and went public in 1936. In 1998, it was bought out by the mining company Carmeuse for $192 million, which is the equivalent of $319.2 million today. On March 5, 1942, it received the Army-Navy "E" Award for outstanding wartime production, and it was the first corporation to be given it. Dravo Corporation ranked 72nd among U.S. corporations in the value of World War II military production contracts. Sadly, everyone who worked on either shipyard between the 1920s and the 1980s was exposed to asbestos, a toxic mineral. Exposure to asbestos is responsible for asbestosis, lung cancer, and mesothelioma, among other respiratory system diseases.
