My father, Michael Gwinnell, who has died of leukaemia aged 78, was passionately committed to supporting the arts, especially classical music, which was a great love throughout his life.
As an investment expert with the asset management firm Schroders from 1967 onwards, Michael earned money that allowed him to become a modest philanthropist in the arts world. He also gave his time, advice and expertise to many musical charities, notably the London Suzuki Group, the Young Classical Artists Trust and the Viola Commissioning Circle. Later he worked for Atlantic Philanthropies, a private charitable giving foundation, as their head of investment.
