Family and education

Leonhard Ennen's parents were simple farmers, the equivalent of sharecroppers in German agricultural society. From 1841 to 1844 he studied theology and philosophy at the University of Münster and the University of Bonn. Following his ordination, he served as vicar and head of the upper Stadtschule, city school, in Königswinter am Rhein, and he remained in this position from 1845 to 1857.

Archive development

While teaching at the school, he became interested in the history of Cologne. In 1849 his Geschichte der Reformation im Bereiche der alten Erzdiözese Köln appeared, in which he examined the impact of the Reformation on the archdiocese of Cologne. He followed this with his Der spanische Erbfolgekrieg und der Churfürst Joseph Clemens von Köln, a study of the War of the Spanish Succession and the role the Elector Joseph Clemens played in this contest, published in 1851. His superiors at the education ministry sent him to Paris, to study archive development and management: the fruit of this study, Frankreich und der Niederrhein, oder Geschichte von Stadt und Kurstaat Köln seit dem 30jährigen Kriege bis zur französischen Occupation, appeared in two volumes in 1855 and 1856. This study of France's relationship with the states of the lower Rhine during the Thirty Years War attracted attention to his talents as an historian, and on 1 August 1857 he was appointed director of the Historisches Archiv der Stadt Köln (Historical Archive of the City of Cologne).

With other historians, notably Anton Fahne (1805–1883), he helped to found the Historischen Verein für den Niederrhein (Historical Society of the Lower Rhine) in 1854, and served as the society's first secretary. He continued to identify, categorize, and publish volumes on the sources and documents of the history of Cologne. He died in Cologne on 14 July 1880.
