Johann Heinrich Alsted, "the true parent of all the Encyclopædias", was a German-born Transylvanian Saxon Calvinist minister and academic, known for his varied interests: in Ramism and Lullism, pedagogy and encyclopedias, theology and millenarianism. His contemporaries noted that an anagram of Alstedius was sedulitas, meaning "hard work" in Latin.

The Herborn Academy was a Calvinist institution of higher learning in Herborn from 1584 to 1817. The Academy was a centre of encyclopaedic Ramism and the birthplace of both covenant theology and pansophism. Its faculty of theology continues as the Theological Seminary of the Evangelical Church of Hesse and Nassau. The institution held the principle that every theory has to be functional in practical use, therefore it has to be didactic.
