Ilarie Voronca (pen name of Eduard Isidor Marcus;[1]: 75 31 December 1903, Brăila – 8 April 1946, Paris) was a Romanian avant-garde poet and essayist.
Only a year later, Voronca adopted a change in style, adhering to the modernist manifesto published in Contimporanul and contributing to literary magazines such as Punct and Integral.
Soon after that, his creations gained a regularity, and he was published frequently — especially after he settled in France (1933) and began writing in the French language.
There followed: L'Apprenti fantôme ("The Apprentice Ghost"; 1938), Beauté de ce monde ("This World's Beauty"; 1940), Arbre ("Tree"; 1942).
He never finished his Manuel du parfait bonheur ("Manual for Perfect Happiness"), committing suicide later in the same year.
