**James Hardy Wilkinson** (

27
September,

1919 –

5
October,

1986) was a prominent figure in
the field of

numerical analysis,
a field at the boundary of

applied
mathematics and

computer
science particularly useful to

physics
and

engineering.

## Early life

Born in
Strood, England, he attended
the Sir Joseph Williamson's Mathematical
School in Rochester. He studied at Trinity College,
Cambridge, where he graduated top of the class.
## Career

Taking up
war work in 1940, he began working on ballistics but transferred to
the National Physical Laboratory in 1946, where he worked with Alan Turing on the ACE
computer project.
Later, Wilkinson's interests took him into the numerical analysis
field, where he discovered many significant

algorithms.

## Recognition

He received the

Turing Award in 1970
"for his research in numerical analysis to facilitate the use of
the high-speed digital computer, having received special
recognition for his work in computations in linear algebra and
'backward'

error analysis." In the
same year, he also gave the

John von
Neumann Lecture at the

Society for
Industrial and Applied Mathematics.

The

J.
H.
Wilkinson
Prize for Numerical Software is named in his honour.

## Personal life

He married Heather Ware in 1945. They had a son.
