JACKSON, EDWARD PAYSON (Mar. 15, iS40-Oct. 12, 1905), educator, author, the son of Congregational missionaries, Rev. William C. and Mary A. (Sawyer) Jackson, was born in Erzerum, Turkey. When five years old he was brought by his parents to the United States, the journey from Erzerum to the Black Sea being made on donkeys, over what was practical- ly the route of Xenophon and the Ten Thousand. After study at Phillips Andover Academy, he entered Dartmouth College in 1856, remaining one year. In 1860 he enrolled at Amherst, where he completed his sophomore year, but did not graduate though he was given the honorary de- Jacksott gree of M.A. in 1870. Enlistment in Company D, 45th Massachusetts Infantry, September 1863, interrupted his studies, and he served as private and corporal in the battles of Kinston, White- hall, Goldsboro, Dover Crossing, and Bachel- der's Creek. He was mustered out but reenlisted in Company A, sth Massachusetts Regiment, and was made second lieutenant for bravery. After the war he taught at Whitehall, N. Y., served for one year as president of the Ladies' College, Ottawa, Canada, and then as principal of the High School at Holyoke, Mass., until 1870. For the next seven years he was principal of the High School at Fall River, Mass., and from 1877 to 1904, an instructor in the Boston Latin School. As a teacher he inspired his pu- pils with his own enthusiasm for the sciences, of which his favorite subjects were zoology and physics. He was a self-taught astronomer and made an unusual set of star charts for classroom use. Among his scientific publications are: An Astronomical Geography (1870); Manual of Zoology (1884); and The Earth in Space (1887). He also wrote a novel, A Demigod (1886), which appeared anonymously and aroused much interest and curiosity at the time. Character Building (1891), which is probably his best known and most influential publication, consists of the familiar talks of a teacher with his pupils on the conduct of life and was award- ed a prize by the American Secular Union for the best essay on the instruction of "children and youth in the purest principles of morality without inculcating religious doctrine." In ad- dition, he was a contributor to magazines, for which he wrote nearly a hundred essays, poems, scientific articles, and monographs on various subjects. Many of his articles had wide circula- tion and were used as supplementary reading in grammar and high schools. He was a member of the Authors' Club of Boston and had a wide circle of friends. His physical and mental activ- ities were unwearied, and his work as a teach- er was characterized by much originality. He was twice married: first, on Mar. 26, 1865, to Helen Maria Smith who died Mar. i, 1896; and second, June 24, 1904, to Mrs. Mary Elizabeth Clark. By the former he had three sons and one daughter.
