HOLDEN, EDWARD SINGLETON (Nov. 5, i846-Mar. 16, 1914), astronomer, librarian, descended from Justinian Holden who came with his brother Richard from England to America in 1634 and died at Cambridge, Mass., in 1691, was born in St. Louis, Mo. His parents were Ed- ward (originally Jeremiah Fenno) Holden and Sarah Frances (Singleton) Holden. After the death of his mother when he was three years old he lived with relatives in Cambridge, Mass., where he attended private schools. He was ac- customed to say that his interest in astronomy was aroused during visits to the Harvard Col- lege Observatory where his cousin, George P. Bond [q.v."], was an observer. In 1860-62 he was a student at the Academy of Washington University, St. Louis, and he graduated with the degree of B.S. at Washington University in 1866.

In 1876 he was sent by the government to London to study and report on possible improve- ments in the instrumental equipment of the Ob- servatory. In 1879, he was relieved, in part, from technical duty and appointed librarian, a position for which he was admirably fitted by his great familiarity with astronomical literature. Besides cataloguing the library, he prepared bib- liographies of special subjects, wrote annual re- ports of the progress of astronomy, and popular articles; with Newcomb, wrote Astronomy for High Schools and Colleges (1879), an
