From 1672 he studied at the Albertina in Königsberg, then in 1674 continued his education at the university in Frankfurt an der Oder.[1]

In 1680, he undertook a trip to the Netherlands and to England. In 1687, he became the secretary of Princess Marie Eleonore of Anhalt-Dessau, and in 1689 the secretary of Heinrich of Saxe-Weissenfels, Count of Barby. In 1700 he returned to Berlin as a tutor to Friedrich Wilhelm of Prussia.[1]
