Named after Keplerplatz, which honours the astronomer Johannes Kepler.
The square was named in 1871 after Johannes Kepler, like the Keplergasse in 1862. Kepler (born 27 December 1571 in Weil der Stadt, died 15 November 1630 in Regensburg) was an astronomer and mathematician. After Tycho Brahe’s death in 1601 he became imperial mathematician and court astronomer. The church of St John the Evangelist, consecrated in 1876, stands in the middle of the square.
