The Gatty Marine Laboratory is a science facility located in the coastal town of St Andrews in Fife, Scotland. It is part of the University of St Andrews and home to the Scottish Oceans Institute, an interdisciplinary research institute studying the marine environment, specifically the behaviour, ecology, physiology, population biology and functional genomics of marine organisms. The Gatty Marine Laboratory is known as the place where Richard G. Morris developed the Morris water navigation task in the early 1980s.
The laboratory was paid for by the zoologist Charles Henry Gatty FRS FRSE FLS FGS (1836-1903) during his later life (1892), having to family to leave his fortune to. He paid both for an original timber building (1892)and its permanent stone replacement (1896). Its first Director was William Carmichael McIntosh FRSE. The permanent building was officially opened on 3 October 1896 by Lord Reay, at which point the timber building was abandoned. The building was badly damaged by fire in 1913.
The Gatty Marine Laboratory has been continuously occupied except for the period between 1931 and the end of World War II. The laboratory has its origins in the government-funded St Andrews Fisheries Laboratory, which was founded in 1884. The first director, Professor William Carmichael McIntosh FRS, conducted pioneering work on the taxonomy of annelids and the early life histories of marine fish over more than 50 years. In 1945-46 the Gatty received an operating budget of £50 and was used as a field station by zoologists and botanists based in the Bute Medical Building in the town centre.
