Elijah Hackleman was born at Cedar Grove, near Brookville, Franklin County, Indiana, on the 18th day of October, 1817. His parents and grandparents were of American birth, but his great-grandparents were natives of Germany. Abraham Hackleman, his father, was a native of Lincoln County, North Carolina, born September 25th, 1775, and at an early age moved to Abbeville district, South Carolina; and from there to Scott County, Kentucky, in 1802; and in 1807 came to what was then known as a part of Indiana Territory, now Franklin County. During the war of 1812 he served as a Federal officer in what was called the frontier service, guarding the western settlements from Indian depredations. In February, 1821, he moved to Rush County, about three miles southeast of where the town of Rushville was afterwards laid out. At that time this was the extreme settlement of civilization, and the west was an unbroken wilderness. Here Elijah Hackleman with his trusty axe began at an early age to carve out his own fortune, helped to fell the forest, clear the lands, build the fences, and cultivate the farm, and was subject to all the vicissitudes of pioneer life. Here he aquired habits of industry that have followed him through life.

The narrow limits of education facilities peculiar to pioneer times did not prevent his acquiring an education. He mentally devoured all the books accessible, and it was often said of him that he was never known to be without a book in his pocket, even when at work, availing himself of every opportunity to stock his mind with its contents. He was for some time a student of the Hon. Benjamin R. Reeve, who still resides in Rush County. He afterwards attended the best school the country afforded, the Connersville Seminary, where he soon became quite proficient in mathematics and astronomy. He read law with General P. A. Hackleman, his cousin, now deceased. He was a resident for a short time in 1835 and '36 of Cass County, Illinois, then a part of Morgan County, and during those years, in company with an older brother, Abner Hackleman, made extensive explorations west of the Mississippi River, through the present State of Iowa, and in the latter year returned to Rush County. He was married to Margaret Davisson, daughter of Aaron Davisson, of Monmouth County, New Jersey, on the 28th day of October, 1841.

Several years of his early life were spent in teaching school, and also discharging the duties of the office of Justice of the Peace. In May, 1849, he moved to Wabash County and improved a farm in Liberty Township. In 1852, he was elected Surveyor of Wabash County, and was continued in office three terms by the unanimous vote of the county. In 1859, was elected Clerk of the Wabash Circuit Court, and in 1863 re-elected, serving eight years, the constitutional limit, to the satisfaction of all. At the election in October, 1874, he was elected to the Senate from Wabash and Huntington Counties by the Republican party, a member of which he has been since the disorganization of the Whig party, and was one of the active members of the Senate at the last session of the Legislature.

Senator Hackleman is one of those affable, kind, unassuming gentleman, always ready to do an act of kindness, and to administer to the wants of his fellow-citizens; never had a personal difficulty with any one; never was sick a day in his life, except having a few shakes of the ague the first year he came to the county, so prevalent on the Wabash at that time. He is temperate, never having used intoxicating liquors; is a member of the Christian Church. The Senator has a well-selected library of several hundred volumes of rare and valuable books, where he spends most of his leisure hours, and, when engaged on his farm, can generally be found there. He has also in his library more than one hundred volumes of newspapers, carefully bound. He has for the last forty years kept a dairy of the most noted events coming under his observation, which he finds of value as matters of history.

Mr. Hackleman was the youngest of a family of ten children, of whom he alone survives. His eldest brother, Richard Hackleman, was long a resident of Hancock County, this State. Dr. James Hackleman was one of the early settlers of Wabash. Another brother, Abner Hackleman, was several years a member of the Territorial Legislature of Iowa, and conducted one of the first emigrant companies to Oregon. A fourth brother, Dr. Jacob T. Hackleman, was an early resident of Iowa. He died many years ago.

Senator Hackleman has resided for the last sixteen years in the city of Wabash, but spends a considerable portion of his time on his farm.
