Musician and conductor June Boissier, known as June Gordon, the Marchioness of Aberdeen and Temair, has died aged 95.

She was also a teacher at Bromley High School for Girls (1936-1939) but more famously the musical director and conductor of Haddo House Choral and Operatic Society from 1945 to 2005.

She had served as Deputy Lieutenant for Aberdeenshire, was a Commander of the Order of St John of Jerusalem and held a variety of advisory and educational appointments. She was a governor of Gordonstoun School, of the Royal Scottish Academy of Music and Drama and of the Royal College of Music.

Despite her success and standing across the social and political spectrum she remained at heart an effective and enthusiastic music teacher .

She was appointed MBE in 1971 and CBE, for her chairmanship of the Scottish Children's League, in 1989.

Beatrice Mary June Boissier was born on on the Isle of Wight on December 29, 1913, to Arthur Paul Boissier, an assistant master and teacher of mathematics at the Royal Naval College at Osborne.

She studied an the Royal College of Music and in 1939 married David Gordon, later the fourth Marquess of Aberdeen. They lived at and ran the Haddo estate.

The Haddo House Choral Society was their joint interest and from small beginnings became one of Scotland's major cultural attractions, hosting a musical festival weekend each year.

Her achievements were put down to being able to foster the involvement of local audiences and amateur choruses with professional instrumentalists and singers – some highly illustrious, some young and new to the art - but always well-chosen. Recruiting her singers mostly from the villages and farms around her husband’s family seat some 20 miles north of Aberdeen, she shaped them into a choir that could tackle a wide range of work.

British composers, especially Elgar, were her special interest and she excelled in their work. She was hailed by the Royal Society of Edinburgh in 1981 as the first musician of her generation to grasp the importance of performing 'The Apostles' and 'The Kingdom' together."

In November 2003 the chorus, with James Loughran as conductor, sang The Dream of Gerontius for her in tribute to her 90th birthday.

She died at Ellon, Aberdeenshire, on 22 June 2009.

Her husband died in 1972 aged 88. She was survived by their four adopted children.
