Merritt-Chapman & Scott, nicknamed "The Black Horse of the Sea", was a noted marine salvage and construction firm of the United States, with worldwide operations. The chief predecessor company was founded in the 1860s by Israel Merritt, but a large number of other firms were merged in over the course of the company's history. It was taken over in the 1950s by famed corporate raider Louis E. Wolfson. It ceased operation in the late 1960s or early 1970s.
