Hugo Ferdinand de Waal (16 March 1935 – 6 January 2007[1]) was Principal of Ridley Hall, Cambridge from 1978 to 1991 and the suffragan Bishop of Thetford from 1992 until 2000.[2]
He was born at Jember on East Java and educated at Tonbridge School and Pembroke College, Cambridge,[3] before embarking on an ecclesiastical career with a curacy at St Martin in the Bull Ring[4] after which he was Chaplain at his old college then Rector of Dry Drayton. Following this he was Vicar of St John the Evangelist, Blackpool[5] and then (his final appointment before appointment to the episcopate) principal of Ridley Hall theological college in Cambridge (1978–91).
He was made a deacon on Trinity Sunday 1960 (12 June) at St James' Church, Handsworth and ordained a priest the Trinity Sunday following (28 May 1961) at St Augustine's Church, Edgbaston — both times by Leonard Wilson, Bishop of Birmingham; he was consecrated a bishop on 17 January 1992 at Westminster Abbey.
In retirement he continued to serve the Church as an honorary assistant bishop within the Diocese in Europe until his death.
