 He inherited the family estate in Ludwigsdorf in 1623, but passed it on to his brother Balthasar in exchange for the right to keep a few small rooms in the family home.He lived a very reclusive life and rarely ventured forth from this room – only in 1634 to attend to those suffering from plague, and in 1640 to challenge the rhetoric of Georg Seidel, a Lutheran preacher from Oels whom Franckenberg regarded as intolerant.Tired of this and other confrontations, and mindful of the fact that events of the Thirty Years’ War were moving in the direction of Silesia, Franckenberg moved to Danzig via Breslau in 1641, where he lodged until 1649 with the astronomer Johannes Hevelius, who introduced him to Copernican astronomy.
