7896 Švejk | Discovered 1995 Mar. 1 by Z. Moravec at Klet. |
Named for a literary character created by Jaroslav Hašek, Czech writer and humorist (1883-1923). His "good soldier" Josef Švejk is devoted to the disintegrating Austrian-Hungarian monarchy regime, but by his simplicity (or perhaps his ingenuity) he helps to reveal its flaws. |
