Sydney Samuel Hough

FRS (11 June 1870, Stoke Newington – 8 July 1923, Gerrards Cross, Buckinghamshire) was a British applied mathematician and astronomer.

[1][2] Hough studied at Christ's Hospital and then obtained a scholarship to Cambridge.

When he first joined Gill, Hough was outstanding in applied mathematics but had little experience in practical astronomy — however, Hough learned quickly from Gill and provided valuable assistance.

Hough concentrated on the completion of Gill's programme and compiled five of the twelve volumes of the Southern African part of the Carte du Ciel.

Hough measured with high accuracy the positions of more than 20,000 stars.
