Carlos Drummond de Andrade

Carlos Drummond de Andrade () (October 31, 1902 – August 17, 1987) was a Brazilian poet and writer, considered by some as the greatest Brazilian poet of all time.

He has become something of a national cultural symbol in Brazil, where his widely influential poem "Canção Amiga" ("Friendly Song") has been featured on the 50-cruzado novo bill. Provided by Wikipedia
