Clarence Bicknell, from 1897, was devoted to Esperanto as a universal language which would bring peoples of the world together.
He attended the first three Esperanto congresses (Bouogne 1903), Geneva (1906) and Cambridge (1907)), then Cracow in 1912 and Paris in 1914. By then, the rumblings of World War would have dominated the thoughts of the delegates and would frustrated their ideals.
We enjoyed this charming YouTube video of the Congresses sent to us by Helen Blanc-Francard. Thanks!
