Swiss Protestant (Protestant Heritage) minister, historian of the Reformation, and advocate of Evangelical (Free Church) Christianity.

The son of Protestant refugees from France, Merle d'Aubigné studied theology at Geneva and was ordained in 1817. While studying in Germany during the anniversary celebration of the German Reformation at Eisenach, he decided to write a history of Martin Luther (Luther, Martin) and his time. After further work in Berlin, where he was influenced by the church historian J.A.W. Neander, he served as pastor at Hamburg and court preacher in Brussels. Returning to Geneva, he became a professor in the theological school of the Evangelical Society of Geneva.

Merle d'Aubigné's major work, in two parts, consists of the popular Histoire de la Réformation du seizième siècle (1835–53; History of the Reformation of the Sixteenth Century, 1838–41) and the more scholarly Histoire de la Réformation en Europe au temps de Calvin (1863–78; History of the Reformation in Europe at the Time of Calvin). Although considered partisan toward the Presbyterian church organization, he revitalized Protestant church historical scholarship and assembled more source documents than any other historian up to his time.
