Jacobs near Waynesboro, Franklin County, Pa., the son of Henry and Anna Maria (Miller) Jacobs. His grandfather, Martin Jacob, emigrated in 1753 from Preursdorf in Alsace, settling first in Fred- erick County, Mi, but later pushing into the wilderness of Washington County, Pa. He gave a portion of his land for a church and a school, the locality thence gaining the name of Jacob's Church. Michael Jacobs' mother died in 1810 and his father, a farmer, in 1822, leaving the boy to be reared by relatives. He entered the prep- aratory department of Jefferson College at Can- onsburg, Pa., in 1823 and graduated second in the class of 1828. For a short time he taught in a boarding school at Belair, Mi, but in April 1829 he went to Gettysburg, Pa., to assist his elder brother David at the Gettysburg Gymna- sium. In his effort to conduct the Gymnasium single-handed, David Jacobs (1805-1830), a man of saintly life and brilliant promise, had sacri- ficed his health and was already dying. In 1832, when the school was reorganized as Pennsyl- vania (now Gettysburg) College, Michael was elected professor of mathematics and natural sci- ences and held this post until his retirement, be- cause of failing health, in 1866. In 1832, having read theology privately, he was licensed by the West Pennsylvania Synod. In his doctrinal opin- ions he was a whole-hearted conservative; his only recorded outburst of indignation occurred on his reading S. S. Sdimucker's Definite Plat- form. On May 3, 1833, he married Julianna M. Eyster of Harr isburg. Although modest and even diffident, he exercised a strong influence over his pupils and eventually over a good part of the General Synod of the Lutheran Church. His scientific attainments, considering his isolation and straitened circumstances, were respectable. He constructed most of the physical and chem- ical apparatus that he used, won something more than local celebrity as a meteorologist, and suc- ceeded, about 1845, in preserving fruit by can- ning. This process, although it had been used in France for some twenty years, was then un- known in rural Pennsylvania. His Notes on the Rebel Invasion of Maryland and Pennsylvania and the Battle of Gettysburg (Philadelphia, 1864; 7th ei, Gettysburg, 1909) was based on careful personal observation. He served three terms as president of the West Pennsylvania Synod and three terms as treasurer. After his retirement he continued to live in Gettysburg, enjoying his books and his garden until a few days before his death, [There is a memoir by Jacobs' son, Henry Eyster Jacobs, in J. G.

JACOBS, WILLIAM PLUMER (Mar. 15, i842-Sept. 19, 1917), Presbyterian clergyman, was born in York County, S. C, the son of the Rev. Ferdinand and Mary Elizabeth (Redbrook) Jacobs. His father was the founder of the York- ville Presbyterian Church and conducted girls' schools in Yorkville (York), S. C., Charleston, S. C., Fairview, Ala., and Laurensville (Lau- rens), S. C. At the age of sixteen William en- tered Charleston College. He was a serious stu- dent and decided that year to give his life to Christian work. In 1859 he was appointed to re- port the proceedings of the South Carolina Sen- ate for the Carolinian and in 1860 he reported the session at which the ordinance of secession was passed. At nineteen he entered the Columbia Theological Seminary. One of his professors, James Henly Thornwell [q.vJ], so impressed Jacobs that later he named an orphanage for him. Resuming his journalistic activities, he reported at Augusta, Ga., 1861, the proceedings of the General Assembly of the Presbyterian Church in the United States, the first Assembly held by the seceding Southern Presbyterians. After finishing his course at Columbia he as- sumed the pastorate of a Presbyterian church of forty-seven members in Clinton, S. C., at that time a small crossroads village. Here, in 1864, he began a work that lasted half a century. The state was emerging from the war and entering the Reconstruction era, and he believed that a small church, properly guided, could be a great pow'er in the social welfare of the community. He saw the need and dreamed of a home for orphans; educational facilities were lacking and he planned a high-school association, which grew into a college, and a library association for adult education. In order to further these schemes he established in 1866 a paper called True Witness, which was succeeded by Farm and Garden, and this by Our Monthly (still issued by the Thorn- well Orphanage Press), By 1875 his dream of an orphanage was in part realized by the opening of the first cottage, housing eight orphans. Dur- ing the forty-three years of his presidency of Thornwell, as the orphanage was called, it grew to fourteen homes, housing more than three hun- dred children. The members of his church stood behind him and with their aid Clinton Academy, which developed into Clinton College in 1880, was established. This institution later became the property of the presbyteries of the State and 568
