Gerhard Schneemann (born at Wesel, Lower Rhine, 12 February 1829; d. at Kerkrade, Netherlands, 20 November 1885) was a German Jesuit.
After studying law for three years, he entered the seminary at Münster where he was ordained subdeacon in 1850. He became a member of the Society of Jesus, 24 November 1851, and was ordained priest on 22 December 1856.
For some years he taught philosophy at Bonn and Aachen, and subsequently lectured on church history and canon law in the Jesuit scholasticate at Maria Laach Abbey.
His first notable publication was "Studien über die Honoriusfrage" (Freiburg, 1864) against the opinion of Ignaz von Döllinger. Between the years 1865 and 1870, he contributed a number of dissertations to "Die Encyclica Papst Pius IX" and "Das öcumenische Concil", two series of papers that were published at Freiburg under the general title of Stimmen aus Maria-Laach, later called Stimmen der Zeit. In 1871 the Stimmen became a regular monthly review and for six years was edited by Schneemann.
He was the chief promoter in the collaboration and publication of the "Acta et decreta sacrorum conciliorum recentiorum", commonly called "Collection Lacensis", and died while preparing the documents of the First Vatican Council for the seventh and last volume. His work "Controfersiarum de divinae gratiae liberique arbitrii concordia initia et progressus" (Freiburg, 1881), was the occasion of a renewed controversy on the nature of grace and free will.
