Daniel Angelocrator

Daniel Angelocrator (1569 – 1635), real surname Engelhardt, was a German Reformed minister.

Life Daniel Angelocrator was born Daniel Engelhardt on 19 October 1569 in Korbach, in the Landgraviate of Hesse-Kassel.

He studied theology at the University of Marburg and the University of Franeker from 1588 to 1589. Early in his career, he worked as a tutor, accompanying two young aristocrats during their studies at Marburg and Helmstedt.

In 1594, a disagreement with his father over his Calvinist beliefs led him to leave home.

In 1617, he published Doctrina de ponderibus, monetis et mensuris per totum terrarum orbem usitatis, a treatise on weights, measures, and coinage used in different parts of the world, which was expanded in a later edition of 1628.
