Dr Hyam was born on 16 May 1936, at Isleworth, Middlesex. He was educated at Isleworth Grammar School after which he did his National Service with the RAF (1954-1956, Instructor Training course). He was an undergraduate at St John's College, Cambridge from 1956 to 1960, where he received First Class honours in both parts of the Historical Tripos. His entire career since 1960 has been spent at Magdalene College Cambridge.
For most of his working life, he has been essentially an archival historian, exploiting especially the resources of The National Archives at Kew in order better to understand government policy towards the British Empire. His research took him to South Africa, Swaziland, Lesotho, India and Sri Lanka.
As a Fellow of the College, apart from teaching duties, his interests have focused on the College and the Old Libraries, the Archives, and the College Magazine (of which he was editor 1963-64, 1986-1997, and 2008-09). He is also an amateur calligrapher (exhibited, Ely Cathedral, 2016).
