James Hardy Wilkinson (09/27/1919–10/05/1986)

图灵奖获得时间：
1970年。第五位图灵奖获得者 。

图灵奖引用(Turing Award Citation) ：

“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. ”

【笔者译：】

“ ( 授 予 James H. Wilkinson 图 灵 奖 以 表 彰 其 在 )数值分析(numberical analysis)研究领域的杰出贡献。其工作加速了数字计算机(在科学计算中)的使用。Wilkinson在线性代数和向后误差分析(backward error analysis)的创造性工作也获得了非常大的成功。”

【笔者注：】

在数值分析中，我们知道著名的James H. Wilkinson多项式:

which has k roots: 1, 2, …, k.

The problem of finding the roots is ill-conditioned: A small change in one coefficient can lead to drastic changes in the roots. Wilkinson’s polynomial of degree 20 has 20 roots, but, as the graph below shows, the function becomes almost horizontal near the x-axis.

另外，James Milkinson也是Pilot ACE计算机的主要贡献者之一。Pilot ACE是英国最早期的计算机之一。
