 In pursuit of an accurate printer for the Tabulae Rudolphinae, he moved to Ulm near the end of 1626 and remained there until the end of 1627. In July 1628 he went to Sagan to enter the service of Albrecht von Wallenstein (1583–1634). He died on November 15, 1630 at Regensburg, where he was to present his financial claims before the imperial authorities (for Kepler’s life, Caspar’s biography (1993) is still the best work. KGW 19 contains biographically relevant documents).
