Jacob was the son of the goldsmith, shopkeeper, councilor and mayor of Jena Erasmus Flach and his wife Dorothea Engelhard. After he had received his first education at the Jena City School, he was entered in the registry of the Jena University in the winter semester of 1553 and re-enrolled there in the winter semester of 1558. Here he first completed philosophical studies with Johann Stigel , Victorin Strigel and Johannes Rosa . He continued these studies on November 19, 1559 at the University of Wittenberg . Here he saw Philipp Melanchthon in the last years of his life and attended Erasmus Reinhold's lectures . After he had acquired the academic degree of a master's degree in philosophy in Wittenberg in March 1560, he returned to Jena.

Here he became an adjunct at the philosophical faculty in 1561 and began alongside medical studies under Johannes von Schröter , Gervasius Marstaller (* around 1520 in Freiburg im Breisgau; † June 3, 1578 in Celle) and Michael Neander .

These are doctoral disputes, where he acted as a present tense, and letters of invitation or congratulations on joining the rector's council. Flach became known as a connoisseur of local botany. He regularly carried out excursions with his students to the Jena area.
