John Macnaghten Whittaker

In retirement he expanded his other interests in art and archeology, collecting watercolours and Persian antiques. He died 29 January 1984.

After the war he returned to Liverpool, becoming Dean of Science, then in 1953 moved to Sheffield to take up the post of Vice-Chancellor of the university. During his office the University expanded from 2500 to 7000 students, requiring the appointment of many new staff and the construction of many buildings. However, he also had to oversee the first closure of an English university department, the Department of Mining. His office covered the centenary celebration of the University in 1955, including a visit by the Queen. He retired from this position in 1965, and was honoured by being given the Freedom of the City of Sheffield.

During the Second World War he served with the Royal Artillery including time in the 8th Army on Field-Marshal Montgomery's staff in Egypt and Tunisia 1942/43. In 1944/45 he was Scientific Advisor to the Army Council and rose to the rank of Lt Colonel.

In 1933 he married Iona Mhari Natalie Elliott: they had two sons.

He was awarded a doctorate (DSc) in 1929, followed by a fellowship at Pembroke College, Cambridge, before becoming a professor of pure mathematics at Liverpool University in 1933.

In 1927 started his academic career as an assistant lecturer in Mathematics at Edinburgh University. In 1928 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were Ralph Allan Sampson, Charles Glover Barkla, Sir Charles Galton Darwin and George James Lidstone.

There were early papers (1926–28) on quantum theory, but his main work was on complex analysis. J. M. Whitaker also made some significant development in the cardinal function theory of his father, E. T. Whittaker. In 1948 he won the Adams Prize, jointly with Burkill, Chandresekhar, and Hayman. In 1949 J. M. Whitaker was elected a Fellow of the Royal Society, an honour already held by his father – they were the only parent and child to have this simultaneously.

He was educated at St Salvator's School in St Andrews then Fettes College in Edinburgh. He then studied Maths and Physics at Edinburgh University from the age of 15, graduating MA in 1924. He followed this by three years at Trinity College, Cambridge, gaining a second MA in 1927.
