John Goldingham

From Wikipedia, the free encyclopedia

John Goldingham was the first official astronomer of the Madras Observatory, appointed in 1802. Goldingham headed the Madras Survey School later which grew into the Guindy Engineering College and then Anna University. Born in London in 1767, Goldingham was hired by astronomer-sailor Michael Topping as his assistant in 1788.

Goldingham was put in charge of building an observatory in 1792, and later appointed as the Presidency Civil Engineer in 1800. Although a mathematician, he managed to learn both astronomy and engineering. In 1796, he married Maria Louisa Popham, niece of Admiral Sir Home Riggs Popham, in St. Mary's in Fort St. George. In 1802, Goldingham formulated the Madras time which was 5 hours and 30 minutes ahead of GMT thus paving the way for it to be adopted a century later as the Indian Standard Time in 1906.

In 1800 he designed the Banqueting Hall (now Rajaji Hall), for which he was granted a commission of 15% on all bills. After the Board of Directors found that Goldingham had drawn 22,500 pagodas¹ as commission on the 180,000 spent on the work till September 1801, the commission was suspended.

He then returned to his work as Government Astronomer, in the course of which he published two volumes of observations: one of them contains his observations on the length of the pendulum, the velocity of sound, of meteorolgical phenomena, as well as determinations of the longtitude of Madras, and a discussion of the longititudes of the three Presidencies.

He retired back to England, where he died at Worcester, in July 1849. He was a Fellow of the Royal Society, the Royal Geographical Society, and the Royal Astronomical Society.
