Who is Baudelaire from The Poetics of Space and what is their importance?

Baudelaire is a French poet. Baudelaire uses the term "vast" to describe for him most naturally, and ironically, the infinity of intimate space. Bachelard claims his use of the term is more appropriate with intimate meaning. Baudelaire does use the term in a number of cases that Bachelard calls "astonishing variety," for which he provides examples.
