Maud MacCarthy (4 July 1882 – 2 June 1967), was an Irish violinist, singer, theosophist, writer, poet, esoteric teacher and authority on Indian music.
However, by 1891 she had returned to Britain to study the violin at the Royal College of Music, London, as a pupil of Enrique Fernández Arbós.
Despite strong opposition from family and friends, Maud and John Foulds left their respective spouses and lived together from 1918 onwards.
In 1929, while living in the East End of London, they met a young man at a local social event whom they commonly referred to as 'The Boy'.
Maud returned to India with John Foulds and William Coote in 1935 where 'The Brothers' continued their teachings through 'The Boy', making a profound impact on thousands of people in search of spiritual meaning.
