Correction to: In search of historical roots of the extraterrestrial impact theory, II: Two unknown German pioneers from the 1850s, Ludwig Pfeil and Karl Reichenbach (International Journal of Earth Sciences, (2021), 110, 3, (1109-1115), 10.1007/s00531-021-02004-0)

Due to erroneous information in the pictorial material available on the Internet in 2019–2020, a major amendment for Fig. 1 is required. The alleged portrait of count Ludwig von Pfeil, a land-owner from Lower Silesia, actually depicts Fürst (prince) Gebhard Leberecht von Blücher (https://www.alamy.de/fotos-bilder/prinz-bl%C3%BCcher.html?blackwhite=1), Prussian field marshal, a hero of the Napoleonic Wars (also related with Lower Silesia)! Fortunately, the quoted source of this image – “Illustrirte Zeitung” from 1856—was digitized by the Österreichischen Nationalbibliothe in 2021 (https://anno.onb.ac.at/cgi-content/anno?aid=izl). Thus, we can now exhibit lithographic likeness of true Ludwig Pfeil, an unknown German pioneer of the extraterrestrial impact theory.
