Chandler, Seth Carlo

 

Born Sept. 17, 1846, in Boston; died Dec. 31,1913, in Wellesley, Mass. American astronomer.

Chandler graduated from Harvard University in 1861 and was a staff member of the Harvard Observatory from 1881 to 1904. His principal works are devoted to latitude variations and the motion of the earth’s poles. On the basis of approximately 33,000 observations he concluded that latitude variations consist of two periodic components: one with a period of a year and one with a period of 14 months (Chandler period). Chandler also investigated variable stars.
