Education

Ingham was born in Northampton. He went to Stafford Grammar School and Trinity College, Cambridge.[1]

Research

Ingham supervised the Ph.D.s of C. Brian Haselgrove, Wolfgang Fuchs and Christopher Hooley.[3] Ingham died in Chamonix, France.

Ingham proved in 1937[5] that if

for some positive constant c, then

for any θ > (1+4c)/(2+4c). 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

gn < pn5/8,

where pn the n-th prime number and gn = pn+1pn denotes the n-th prime gap.
