January 12, 1670, Hohenfelden, Germany (near Erfurt).
December 25, 1745, Siebleben, Gotha, Thuringia, Germany.
Schmidt’s father was Johann Jakob Schmidt, pastor at Hohenfelden. Johann the younger matriculated at the University of Jena in the autumn of 1688, and in 1691 went to Erfurt to attend lectures by Breithaupt and August Francke.
He spent part of 1692 traveling in northern Germany, and 1693–1696 mostly worked as a private tutor in Gotha.
On the twelfth Sunday after Trinity, 1697, he began work at Siebleben as substitute (curate in charge), and on fourth Sunday in Advent, 1698, as pastor there.
