Hector Hodler (1 October 1887, in Geneva – 31 March 1920, in Leysin, Switzerland) was a Swiss Esperantist who had a strong influence on the early Esperanto movement.
As a 16-year-old, Hector Hodler learned Esperanto with his classmate Edmond Privat, and founded soon afterward a club and the journal Juna Esperantisto ("The Young Esperantist").
In 1907 he took over the editorship of Esperanto magazine from its founder Paul Berthelot and made it a significant journal dealing with organizational questions from the language community.
He signed his articles with the initials A. R. The proposals of Rousseau and Carles were melded with his plans, were discussed in his magazine and received a warm welcome.
After the death of Harold Bolingbroke Mudie in 1916, the presidency of the World Esperanto Association was vacant until after the war, when Hodler was elected to succeed him.
