Arthur Kingsley Porter

Arthur Kingsley Porter (1883 – 1933) was an American art historian and medievalist. Porter's most significant contribution has been his revolutionary studies and insights into the spread of Romanesque sculpture. His study of Lombard architecture is also the first in its class.

Porter bought the late nineteenth century Glenveagh Castle (constructed 1870–1873) in County Donegal in 1929, and spent several months there each year, learning Irish and studying archaeology and culture. In 1933, he went out for a walk along the beach on Inishbofin Island Co. Donegal where he owned a holiday home and vanished. Other reports suggest he set off alone in his little boat and disappeared in a storm. Some refused to believe the truth of this St Brendanish death and insisted that Kingsley remained alive and in hiding. An inquest was inconclusive, but drowning was assumed to have been the most likely explanation for his disappearance.
