ployment as a tutor in English. Out of curiosity
he attended a Methodist church on Vine Street
between Fourth and Fifth and was converted late
in 1839 bytne Rev« William Nast [q.v.]. Though
diffident of his qualifications, he yielded to Nast's
persuasions and prepared himself for ordination.
In September 1840 he married Amalie Therese
Nuelsen, born in Germany at Norten near Han-
nover, who had been converted from Catholicism
to Methodism in Cincinnati. She bore him eight
children, was his capable assistant in his work,
and lived to mourn him. His missionary career,
which first brought Methodism to the Germans
in the upper Mississippi Valley, to Germany, and
to Switzerland, began in 1841, when Bishop
Thomas Asbury Morris sent him to open a mis-
sion in St. Louis. Rowdies blocked the doors
of his chapel with cow dung and threatened to
tar and feather him, but he persisted and made
converts. He then set up preaching stations at
Galena, Dubuque, and other points and became
presiding elder of the St. Louis German District
in 1844 and of the Quincy German District in
1845. I*11§48 he petitioned the General Confer-
ence to send him to Germany to begin activities
there. After a year of rest he sailed in October
1849, established his headquarters in Bremen,
and started a congregation. As helpers were sent
to him, he carried the work to other towns in
Germany and even into Switzerland. In the north
he won followers by his command of his boyhood
Plattdeutsch. For twenty-two laborious years
he acted as pastor, book agent, editor of publica-
tions, founder and director of a hospice and semi-
nary, superintendent of missions, and presiding
elder of the Oldenburg District He was the au-
thor of a Handbuch des Methodismus (Bremen,
1853; 1854), a Geschichte des Methodismus,
Erster Thett (Bremen, 1870; 1871), tracts, and
other items. Methodism was distinctly unwel-
come in Germany, but through Jacoby's sagac-
ity and devotion it gained a foothold. Weary
with years of unremitting toil, he returned to the
United States late in 1871 and became pastor
of the Soulardgemeinde in St. Louis and soon
after presiding elder again of the St. Louis Dis-
trict Before many months he was mortally ill.
While awaiting death he compiled Letzte Stun-
denf oder Die Kraft der Religion Jesu Christi im
Tode (1870).

JADWIN, EDGAR (Aug. 7, i86s-Mar. 2,
1931), soldier, engineer, was born at Honesdale,
Pa., the son of Cornelius Comegys and Charlotte
Ellen (Wood) Jadwin. His father, a merchant,
served a term in Congress (1882-84), and the
family traced ancestry back to colonial forebears
in Virginia and Pennsylvania, the first of the
name having been Jeremiah Jadwin who settled
about 1683 on the neck between Chesapeake and
Delaware bays. After a common-school educa-
tion, young Jadwin attended Lafayette College,
Easton, Pa., for two years. He entered West
Point in 1886 and graduated four years later with
the highest honors of his class. He was commis-
sioned second lieutenant, Corps of Engineers,
and after duty with various river and harbor im-
provements, 1890-97, became an assistant to the
chief of engineers, 1897-98. The war with Spain
found him promoted to major and lieutenant-
colonel, 3rd United States Volunteer Engineers,
with command for a time of a battalion of his
regiment at Matanzas, Cuba, where he effected
many sanitary reforms. His subsequent service
included engineering projects on the Pacific coast
and in the vicinity of Galveston, Tex., with con-
struction of a deep-sea channel between Galves-
ton and Houston and engineering safeguards fol-
lowing the great hurricane of the year 1900. He
had reached the grade of major, 1906, when he
was selected by General Goethals as one of his
assistants in the construction of the Panama Ca-
nal. As such, he was division engineer of the
Chagres Division, 1907-08, resident engineer,
Atlantic Division, 1908-11, and his more impor-
tant accomplishments included construction of a
ship's channel through Gatun Lake, and build-
ing the great Gatun Dam and Spillway, as well
as a breakwater at the Atlantic terminus of the
Canal. He was on important engineering work
in the Tennessee District, 1911, assistant to the
chief of engineers at Washington, 1911-16, and
in charge of the Pittsburgh District, 1916-17,
with membership on the Ohio River Board of
Flood Control. Promotion to the grade of lieu-
tenant-colonel had come in 1913.

With the outbreak of the World War, Jadwin
was appointed commanding officer, isth United
States Engineers (Railway),on July6,1917,and
with his regiment overseas was soon engaged in
vast construction projects. He was appointed
brigadier-general, National Army, Dec. 17,1917,
and served as chief engineer of advanced lines of
communication, until Feb. 17, 1918, and as direc-
tor of light railways and roads, American Expe-
ditionary Forces, until Mar. 19, 1918, when he
