Daniel Nicol Dunlop (28 December 1868, Kilmarnock, Scotland – 30 May 1935, London) was a Scottish entrepreneur, founder of the World Power Conference and other associations, and a theosophist-turned-anthroposophist.
He lost his mother at the age of five and was brought up by his grandfather on the Isle of Arran, where he learnt the trade of fishing.
In 1911, with Sebastian Ziani de Ferranti and others, Dunlop helped to found the British Electrical and Allied Manufacturers' Association (BEAMA) in London, which still exists today.
Together with Æ and Yeats he attended meetings of the Hermetic Society and in 1892 founded the magazine "The Irish Theosophist", which he edited until his departure from Dublin in 1897 for the United States.
In 1909 he initiated the Summer Schools, regular international meetings with theosophical lecture cycles and events where participants got to know one another more intimately.
In 1928 he organised the first and only World Conference on Anthroposophy and in 1929 he was elected General Secretary of the Anthroposophical Society in Great Britain.
Dunlop enlisted the help of fellow anthroposophist Walter Johannes Stein in the hope of founding a World Economic Organisation, but his death prevented this.
