Jackson

man, philanthropist, church historian, brother of
George Thomas Jackson [q.v,,], was born in
New York, the son of George T. Jackson, who
came to New York from Dublin, Ireland, in
1834, and was associated in business with Cor-
nelius van Schaick Roosevelt, grandfather of
President Roosevelt. His mother was Letitia
Jane Aiken Macauley, daughter of Samuel Ma-
cauley, a New York physician of Irish birth.
Educated in the public schools and the college of
the City of New York (A.B. 1870; A.M. 1876),
he prepared for the ministry in Princeton Theo-
logical Seminary, 1870-71, and Union Theologi-
cal Seminary, New York, 1871-73. The interest
in church history wakened by the teaching of
Henry Boynton Smith and Philip Schaff [qq.v.~\
of the Union faculty led him to further study in
the universities of Leipzig and Berlin, with
travel in Palestine, 1873-75. He was ordained
May 30, 1876, and became pastor of the Pres-
byterian Church in Norwood, N. J. For the
pastoral office he was richly qualified by en-
thusiastic faith and buoyant friendliness, but
diffidence in public situations and a lack of art
in discourse led him to resign his ministry in
1880.

Returning to New York he gave himself to
social Christian activity and the promotion of
historical scholarship, devoting to these causes
painstaking labor and generous gifts from his
private means. From 1885 he served the Char-
ity Organization Society in various capacities
and for the last nine years of his life was its
vice-president. Convinced that poverty and
crime were closely related, he became recording
secretary of the Prison Association of the State
of New York and by his liberal gifts of money
secured the classification of its extensive collec-
tion of penological literature. To serve these
cherished purposes he edited nine volumes of
useful Handbooks JOY Practical Workers in
Church and Philanthropy (1898-1904) and
served as teacher in the Amity school for Chris-
tian workers. The cause of foreign missions also
claimed him. Hoping for a complete history of
missions in English and having made a mission-
ary bibliography with more than 5,000 titles, he
printed a selection of these in the Report of the
Centenary Conference on the Protestant Mis-
sions of the World . . ., 1888 (2 vols., London,
1889), and later with the cooperation of Rev.
George Gilmore furnished an enlarged and clas-
sified list to E. M. Bliss's Encyclopaedia of Mis-
sions (1891, vol. I, Appendix). Elected to the
board of trustees of Canton (China) Christian
College, now Lingnam University, May 28,1901,
he served henceforth on its faculty committee

Jackson

and from Apr. 15, 1905, to his death was presi-
dent of the board. Always a ready contributor
to the expenses of the College, he finally erected
Jackson Hall as a residence for its president and
provided in his will a legacy of $5,000.

As may be seen by his appreciation of SchafFs
zeal for Christian philanthropy, Christian union,
and theological scholarship (New York Evan-
gelist, Oct. 26,1893), Jackson was a devoted dis-
ciple of that eminent teacher. Many of SchafFs
projects were realized through him. For Schaff
he prepared the material for a Dictionary of
the Bible (1880), and he was associate editor
with Schaff in producing A Religious Encyclo-
pedia: or Dictionary of Biblical, Historical,
Doctrinal, and Practical Theology (3 vols.,
1882-84), better known as the "Schaff-Herzog
Encyclopaedia." He executed SchafFs plan of
a supplementary Encyclopedia of Living Di-
vines (1887) and as editor-in-chief brought to
pass the more elaborate New Schaff-Hersog
Encyclopedia of Religious Knowledge (13 vols.,
1908-14). In New York University, where he
himself, dispensing with salary, served as pro-
fessor of church history from 1895 to his death,
he commemorated his revered master by endow-
ing a Philip Schaff lectureship.

Independently, and with financial loss, Jack-
son produced in 1889 a Concise Dictionary of
Religious Knowledge (rev. ed., 1891; 3rd ed.,
1898). He was editor for religious literature in
Johnson's Universal Cyclopedia (1893-95, 1897
ff.) and for Protestant theology and religious
biography in the New International Encyclo-
pedia (1902-05). He defined church terms
for the Standard Dictionary (1895) and the
New International Dictionary (1900). Without
thought of compensation he edited for the Hu-
guenot Society of America several volumes of
their publication, and to the American Society
of Church History he was even more generous.
He was its secretary, conducted its correspond-
ence, made its programs, edited its Papers,
paid some of its deficits, and joyously provided
luncheon and dinner for its annual sessions. He
was one of the editors of the American Church
History Series (13 vols., 1893-97) and con-
tributed "A Bibliography of American Church
History" to Volume XII (1894). In 1895 he
projected the important series on "Heroes of the
Reformation," and for this at once began his
own biography of Zwingli. This volume, Hul-
dreich Zwingli, the Reformer of German Switz-
erland, his chief production, wrought with mi-
nute care and critical accuracy, appeared in 1901.
To make Zwingli's works accessible in English
he planned with the assistance of other scholars
