Michael Gwinnell (chairman)

Michael has known Lawrence since the latter was at the Junior Guildhall with Michael’s daughter Alice and was thus pleased to help him acquire the use of his Brenzi viola in 2005.  As well as acting as co-trustee with Nigel Brown of the Lawrence Power Viola Trust, Michael is co-trustee of the Lawrence Power Bow Trust.  A graduate of Corpus Christi College, Cambridge, the first half of his career was spent with Schroders in the City of London following which he was principal investment officer for a large off-shore foundation. Michael has been a trustee of numerous charities, mainly in the arts world, including Young Classical Artists Trust and The Almeida Theatre Company.

David Challen CBE

David is a music lover with particular interest in opera and is a trustee of Classical Opera and Mid Wales Music Trust.  He was an original contributor to the Lawrence Power Viola Trust.  A graduate of Trinity College Dublin and Harvard Business School, his distinguished career in the City of London commenced at J Henry Schroder & Co. of which he became Chairman. After Schroders’  investment banking business merged with Salomon Smith Barney he transitioned to senior roles in the European Investment Bank part of Citigroup, becoming Chairman of its EMEA Governance Committee.  He was Senior Independent Director at Anglo American and Smiths Group and recently retired as Deputy Chairman of the Takeover Panel.

Sir Christopher Hum KCMG

Christopher played the viola in the National Youth Orchestra of Great Britain but now focuses on the piano which he enjoys playing in chamber music with friends.  While Master of Gonville and Caius College, Cambridge he hosted the “topping out” concert and lunch party for the Lawrence Power Viola Trust.   Like Michael, he was a trustee of Young Classical Artists Trust.  A graduate of Pembroke College, Cambridge, his distinguished career in HM Diplomatic Service culminated in his appointment as Ambassador to the People’s Republic of China. He is Honorary President of the China Association, and in 2019 was awarded an MA in History of Art and Archaeology of East Asia by the School of Oriental and African Studies.
