Eugène van Nijverseel, who used the pseudonym Evany, was the first assistant of Hergé. He worked with the creator of Tintin between 1929 and 1931, inking the installments of 'Tintin au Congo' and the 'Quick et Flupke' gags that appeared in Le Petit Vingtième. He also illustrated several covers for this supplement of Le XXe Siècle. He also took over the character of 'Totor' in the Le Boy Scout Belge and created a new run of gags from February to July 1930.
