Constance Frederica “Eka” Gordon-Cumming (26 May 1837 – 4 September 1924) was a travel writer and painter. She was born on 26 May 1837 at Altyre, near Forres in Scotland, the 12th child of a wealthy family. Her parents were Sir William Gordon-Cumming, 2nd Baronet, and Elizabeth Maria (Campbell) Cumming. She was the aunt of Sir William Gordon-Cumming, 4th Baronet. She grew up in Northumberland, and was educated at Fulham, London. She taught herself how to paint, and had help from artists visiting her home, including one of Queen Victoria's favorite painters, Sir Edwin Landseer. After spending a year in India in 1867 and writing in In the Himalayas and on the Indian Plains (1884) she became interested in travel.
Gordon-Cumming was a prolific travel writer and landscape painter who traveled the world, mostly in Asia and the Pacific. She painted over a thousand watercolors. Places she visited include Australia, New Zealand, America, China, and Japan. She arrived in Hilo, Hawaii in October 1879, and was among the first artists to paint the active volcanoes. Her Hawaii travelogue, Fire Fountains: The Kingdom of Hawaii, was published in Edinburgh in 1883.
Her best known books are At Home in Fiji and A Lady's Cruise on a French Man-of-War. The latter book resulted from an invitation to join a French ship put into service for the Bishop of Samoa so that he could visit remote parts of his far-flung diocese.
Miss Gordon-Cumming received much criticism from male writers of the era, perhaps because she did not fit in the traditional Victorian role of women, as she often traveled alone and unaided. Henry Adams said her books are a collection of anecdotes without much interest. In any case, her landscape drawings and watercolors seem to be universally admired.
