Morse Diving was an American manufacturer of diving equipment, founded in 1837 in Boston, Massachusetts. The company originated as Fletcher & Morse Co., a brass‑goods manufacturer for the marine industry, and later operated under the name Andrew J. Morse & Son. Over the course of its history the firm produced a range of diving apparatus, most notably commercial diving helmets such as the Mark V and the “#15 Shallow Water Diving Helmet.”
