Jean Tardieu (1903-1995) was a poet, a playwright (of short pieces), a philosopher too apparently. He worked first in publishing and then, very notably and for a long time, in radio broadcasting. Among his writerly preoccupations were existence, identity, and meaning. His way of playing with language reminds me of Ionesco.
