His association with this journal resulted in it being termed an "important voice for the symbolists" (Harry Ransom Humanities Research Center 2004).

When his parents died, Dujardin was the sole heir to their fortune, and he used some of this money to finance the plays Antonia in 1891 and Le Chevalier Du Passé in 1882.

He continued his involvement with journalism throughout his life and this resulted in numerous disputes with authorities, including charges of treason, though he was never convicted.

Dujardin had expensive and lavish tastes for clothing which was deemed "dandyish" for his time, and was known to frequent Parisian night life.

His frivolous lifestyle eventually reduced his finances so he began numerous financial ventures, including gambling and real estate.
