Ernst von Hesse-Wartegg (21 February 1851 – 17 May 1918) was an Austrian – American writer and traveller.
Ernst von Hesse-Wartegg's origins are unknown, but he was thought to have been born in or near Vienna, Austrian Empire.
He had a daughter born out of wedlock who tried in vain to prove her family roots in the 1930s.
In 2012 several research teams could not find more information, only in results published in 2017 it was demonstrated that Hesse-Wartegg was Austrian by birth, but adopted American citizenship in 1887.
In 1894 he went on a trip around the world with South and East Asia as major stops: India, Singapore, Hong-Kong, China, Japan and Korea.
