Mr. Achebe grew up, and grew wiser: “These writers had pulled a fast one on me! I was not on Marlowe’s boat steaming up the Congo in ‘Heart of Darkness’; rather, I was one of those unattractive beings jumping up and down on the riverbank, making horrid faces.”

Mr. Achebe was a poet, professor, short-story writer and critic in addition to being a novelist. His more than 30 other books include the novels “No Longer At Ease” (1960) and “Anthills of the Savannah” (1987). He published several children’s books. He was also the author, controversially, of an essay called “An Image of Africa: Racism in Conrad’s ‘Heart of Darkness.’ ”

While many critics defended Conrad, Mr. Achebe didn’t back down from his assertion that the racism in Conrad was not merely the norm for its time. In a book of essays he quoted earlier writers who, he said, were less backward.

Mr. Achebe was a mentor and role model to a generation of African writers — he’s often referred to as the father of modern African writing. But like many novelists who find success with an early book, Mr. Achebe found himself almost solely defined by “Things Fall Apart.” He spent the last two decades in the United States, teaching at Bard College and then Brown University.

It’s been more than 50 years since the publication of Mr. Achebe’s pioneering and canonical novel; it no longer seems to stand, to a Western audience at any rate, for African writing as a whole. His talent and success have helped spawn an array of postcolonial writing from across the continent. Among the talented young Nigerian writers alone who cite him as an influence are Chimamanda Ngozi Adichie, Adaobi Tricia Nwaubani and Lola Shoneyin.

In 1990 Mr. Achebe was paralyzed from the waist down in a car accident in Nigeria. The following year he gave an interview to Bradford Morrow in Conjunctions magazine.

Mr. Morrow asked him about the accident, and Mr. Achebe spoke about it with stoicism and good humor. “Children are born deformed,” he said. “What crime did they commit? I’ve been very lucky. I walked for 60 years. So what does it matter that I can’t for my last few years. There are people who never walked at all.”

“Things Fall Apart” is, at base, about the strength that human beings find in community. His car accident offered him similar lessons. “It is an opportunity,” Mr. Achebe told Mr. Morrow. “It’s a lesson. It’s so much. It is an enrichment. I’ve learned so much. I’ve learned how much we depend on each other.”
