WALCH, JOHANN ERNST IMMANUEL, the eldest son of the celebrated J. G. Walch, was born at Jena on the 29th of August 1725, where he completed his studies, and where he was appointed professor of divinity in 1759. Natural history divided his studies with ecclesiastical history, and he has left behind him a great number of works in both of these departments of learning. He died December 1, 1778.
The principal works of J. E. I. Walch are as follows:—De Christianorum sub Diocletiano in Hispania Persecutione, 1751; Marmor Hispaniae, 1750; Acta Societatis Latine Jenensis, 4 vols.,
1752-55; Dissertationes in Acta Apostolorum, 3 vols., 1756-61; De Arte Critica Veterum Romanorum Litteraria, 1771; Das Steinreich systematisch entworfen, 2 vols., 1769; and his celebrated Georg Wolfgang Knorr's Sammlung von Merkwürdigkeiten der Natur, &c., 3 vols., 1768-73. This work has been translated into French in 1776, and into Dutch in 1779.
