Sir Archibald Denny, 1st Baronet FRSE LLD (1860–1935), was a Scottish naval architect who was owner of the huge Clyde shipbuilding company of William Denny and Brothers and was granted a baronetcy in 1913, thereby giving birth to the Denny baronets of Dumbarton. Unusually as an owner, he also interested himself directly in the design of ships. He was president of the Institute of Marine Engineers. The company, usually simply referred to as Dennys, had the highest output and tonnage of any of the Clyde shipbuilders, ranking them as one of the world’s largest companies at that time.
