b. 1891
An early Australian Esperanto advocate, he helped spread the language through teaching, editing, and practical writing. His surviving work offers a window into how Australia was presented to international readers in the early 20th century.

by Lauri Laiho, Arthur Maurice Hyde
Born in Melbourne on April 5, 1891, Arthur Maurice Hyde was an Australian Esperantist and public servant. Sources agree that he joined the Melbourne Esperanto Club in 1907, and he later became a prominent figure in the movement in Australia.
He is noted as the author of Kurso en Esperanto (1918), described as the first Australian Esperanto textbook, and as the first editor of La Suda Kruco around 1920–1921. He also served as president of the Australian Esperanto Association in 1921, and reports about his work say he organized an Esperanto course among Chinese communities in New Guinea.
Hyde also wrote under the pseudonym Antoni Delsudo. Book records connect him with Aŭstralio: lando kaj popolo, a work introducing Australia and its people to Esperanto readers, and Project Gutenberg lists him among its authors. Some sources differ on details of his death, so it is safest to say that he was active across the first half of the 20th century.
