(Eugène) Arnold Dolmetsch (24 February 1858 - 28 February 1940), was a French-born musician and instrument maker who spent much of his working life in England and established an instrument-making workshop in Haslemere, Surrey. He was a leading figure in the 20th century revival of interest in Early Music.
Dolmetsch's early life 
The Dolmetsch family was originally of Bohemian origin, but (Eugène) Arnold Dolmetsch, the son of Rudolph Arnold Dolmetsch and his wife Marie Zélie (née Guillouard) was born at Le Mans, France, where the family had established a piano-making business. It was in the family's workshops that Dolmetsch acquired the skills of instrument-making that would later be put to use in his early music workshops.
He studied music at The Brussels Conservatoire and learnt the violin with Henri Vieuxtemps. In 1883 he travelled to London to attend the Royal College of Music, where he studied under Henry Holmes and Frederick Bridge, being awarded a Bachelor of Music degree in 1889.
The early music revival 
Dolmetsch was employed for a short time as a music teacher at Dulwich College, but his interest in early instruments was awakened by seeing the collections of historic instruments in the British Museum, and, after constructing his first reproduction of a lute in 1893, he began building keyboard instruments. William Morris encouraged him to build his first harpsichord. He left England to build clavichords and harpsichords for Chickering of Boston (1905–1911), then for Gaveau of Paris (1911–1914).
He went on to establish an instrument-making workshop in Haslemere, Surrey and proceeded to build copies of almost every kind of instrument dating from the 15th to 18th centuries, including viols, lutes, recorders and a range of keyboard instruments. His 1915 book The Interpretation of the Music of the XVIIth and XVIIIth Centuries was a milestone in the development of authentic performances of early music.
In 1925 he founded an annual chamber music festival, the International Dolmetsch Early Music Festival, which is held every July at Haslemere, in the Haslemere Hall.
Dolmetsch was active in the cultural life of London, and his friends and admirers included William Morris, Selwyn Image, Roger Fry, Gabriele d'Annunzio, George Bernard Shaw, Ezra Pound, George Moore, whose novel Evelyn Innes celebrates Dolmetsch's life and work, and W. B. Yeats.
He was responsible for rediscovering the school of English composers for viol consort (including John Jenkins and William Lawes), leading to Sir Henry Hadow's tribute that Dolmetsch had "opened the door to a forgotten treasure-house of beauty". He was also largely responsible for the revival of the recorder, both as a serious concert instrument, and as an instrument which made early music accessible to amateur performers. He went on to promote the recorder as an instrument for teaching music in schools.
The Dolmetsch family 
Arnold Dolmetsch was married three times. On 28 May 1878 he married Marie Morel of Namur, Belgium (a widow, ten years his senior) but was divorced in 1898. His second wife, to whom he was married on 11 September 1899, in Zürich, was Elodie Désirée, the divorced wife of his brother. This marriage ended in divorce in 1903. Thirdly, he was married on 23 September 1903 to Mabel Johnston, one of his pupils.
Dolmetsch encouraged the members of his family to learn the skills of instrument-making and musicianship and the family frequently appeared together in concerts, playing instruments constructed in the Dolmetsch workshops. Following the death of Arnold Dolmetsch at Haslemere in 1940, his family continued to promote the building and playing of early instruments.
