塞思·卡罗·钱德勒1846—1913

他出生在美国马萨诸塞州波士顿。在中学求学最后几年他是哈佛大学天文台教授本杰明·皮尔士的计算员。

毕业后他成了天文学家本杰明·阿普索普·古尔德的助理。古尔德当时是美国国家大地测量局的主席。之后古尔德到阿根廷国家天文台当台长，钱德勒成为精算师，但不久又重新进行天文学研究。

他最有名的研究是钱德勒摆动（Chandler wobble），他花了三十年时间进行相关研究。

钱德勒也在天文学其他领域进行研究。他发现了北冕座T新星，改善了光行差的计算，以及计算小行星和彗星的轨道参数。

Seth Carlo Chandler, Jr. (September 16, 1846 – December 31, 1913) was an American astronomer, geodesist, and actuary.

He was born in Boston, Massachusetts, to Seth Carlo and Mary (née Cheever) Chandler. During his last year in high school he performed mathematical computations for Benjamin Peirce, of the Harvard College Observatory.

After graduating, he became the assistant of Benjamin A. Gould. Gould was director of the Longitude Department of the United States Coast Survey, a United States Government agency responsible for geodetic surveys. When Gould left to become director of the national observatory in Argentina, Chandler also left and became an actuary. However, he continued to work in astronomy as an amateur affiliated with Harvard College Observatory.

Chandler married Caroline Margaret Herman on October 20, 1870. They were married for 47 years and had several daughters together. Chandler died on December 31, 1913, in Wellesley, Massachusetts.

Chandler is best remembered for his research on what is today known as the Chandler wobble. His research on polar motion spanned nearly three decades.

Chandler also made contributions to other areas of astronomy, including variable stars. He independently co-discovered the nova T Coronae Borealis, improved the estimate of the constant of aberration, and computed the orbital parameters of asteroids and comets.

Chandler was awarded the Gold Medal of the Royal Astronomical Society in 1896 and the James Craig Watson Medal in 1894.

The crater Chandler on the Moon is named after him.
