梭罗 is the standard Chinese rendering of Henry David Thoreau (1817-1862) - author of
《瓦尔登湖》 (Walden) and
《论公民的不服从》 (Civil Disobedience). His writings on nature, simplicity, and resistance shaped figures from Tolstoy to Gandhi to MLK. The same characters also transliterate the Indonesian city Solo (Surakarta) on Java, as in the folk song
《梭罗河》 (Bengawan Solo).
