Ingham was born in Northampton. He went to Stafford Grammar School and Trinity College, Cambridge.Research

Ingham proved in 1937 that if
for some positive constant c, then
for any θ > /. Here ζ denotes the Riemann zeta function and π the prime-counting function.
Using the best published value for c at the time, an immediate consequence of his result was that
where pn the n-th prime number and gn = pn+1 − pn denotes the n-th prime gap.
