Although he wanted to complete an educational trip to France the following year, he accepted the appointment as high school professor of mathematics and poetry in Gdansk in the same year. Crüger was in contact with Tycho Brahe and Johannes Kepler , with whom he discussed research results. Among his students were Johannes Hevelius and Andreas Gryphius , whom he later strongly influenced. In Danzig he belonged to Martin Opitz's circle of poets .
