Short answers, pulled from the story.
Charles Baudelaire is best known for Les Fleurs du mal (The Flowers of Evil), a collection of lyric poetry first published in 1857. He is also credited with coining the term modernity (modernite) to describe the fleeting experience of life in an urban metropolis, and Marshall Berman has credited him as the first Modernist.
Baudelaire, his publisher, and his printer were successfully prosecuted for offenses against public morals following the publication of Les Fleurs du mal in 1857. Six poems were suppressed due to their themes of sex, death, and lesbianism. The judgment was officially reversed on the 11th of May 1949, and the six banned poems were reinstated in France.
T. S. Eliot stated in a lecture delivered in Aix-en-Provence in April 1948 that he was "an English poet of American origin who learnt his art under the aegis of Baudelaire and the Baudelairian lineage of poets." Eliot also quoted the last line of Baudelaire's poem "Au Lecteur" directly in Section I of The Waste Land.
Baudelaire first encountered Poe's work in 1847 and spent roughly two decades translating it into French. His translations, published in several volumes between 1856 and 1865, were considered among the finest French versions of Poe. Baudelaire saw in Poe a precursor and tried to be his French contemporary counterpart.
Jeanne Duval, a French-born actress, was Baudelaire's long-term mistress. Their relationship began around 1842, when she was formerly the mistress of the photographer Nadar, and continued on and off until the end of Baudelaire's life. Baudelaire's family rejected her, but he continued to support her financially even when he had little money himself.
Charles Baudelaire died in Paris on the 31st of August 1867, after suffering a massive stroke in 1866 and spending more than a year in a semi-paralyzed state. His funeral was held at the Saint-Honore d'Eylau church with a few dozen persons in attendance, and he is buried in the Cimetiere du Montparnasse in Paris.
