Mansel Treharne Thomas, OBE (12 June 1909 – 8 January 1986) was a Welsh composer and conductor, who worked mainly in South Wales.
He himself wrote vocal, choral (mixed, female, children's and male voices), instrumental (solo and chamber), band and orchestral music, specialising in setting songs and poetry.
[1] Mansel Thomas's composing career spanned almost 60 years and fell approximately into three periods: up to and including World War II, 1946 to his early retirement in 1965 and 1965–1979.
His first notable composition – "Daffodils"/"Cennin Aur" – was written in the mid-1920s for the newly formed Pendyrus Choir, which rehearsed next to his home in Tylorstown.
The recent availability of his works in publication has done much to regenerate interest and inspire performances not only in Wales but more widely in the UK and internationally in Europe, United States, Canada and Australia.
