Nietzsche's work spans philosophical polemics, poetry, cultural criticism, and fiction while displaying a fondness for aphorism and irony. Nietzsche died in 1900, after experiencing pneumonia and multiple strokes.
He lived his remaining years in the care of his mother until her death in 1897 and then with his sister Elisabeth Förster-Nietzsche. In 1889, at age 44, he suffered a collapse and afterward a complete loss of his mental faculties, with paralysis and probably vascular dementia. He became the youngest person to hold the Chair of Classical Philology at the University of Basel in 1869 at the age of 24, but resigned in 1879 due to health problems that plagued him most of his life he completed much of his core writing in the following decade.
