Sydney Goldstein FRS[1] (3 December 1903 – 22 January 1989) was a British mathematician noted for his contribution to fluid dynamics.
"[1] He was especially known for his work on steady-flow laminar boundary-layer equations and on the turbulent resistance to rotation of a disk in a fluid.
[4] After his mother died he moved to live with an aunt and attended Bede Collegiate School in Sunderland.
At Manchester the influence of Osborne Reynolds and Horace Lamb in fluid dynamics was still felt there and had a strong effect on Goldstein.
Having made a major contribution to the establishment of the Technion, he found the administrative load too heavy[2] and moved again, accepting the chair of Gordon McKay Professor of Applied Mathematics at Harvard University in 1954.
