Twitter users remember Harper Lee and her powerful words

“I think there’s just one kind of folks. Folks.” — Harper Lee

Thousands took to social media to mourn Pulitz­er Prize-winning author and lifelong equal-rights defender Harper Lee, who died Friday at age 89.

Lee died Friday in her hometown—Monroeville, Alabama—where she wrote her famed 1960 novel, “To Kill a Mockingbird.”

“It has never been out of print and is perhaps the most widely loved American novel of the past half-century,” The Guardian reported. “The book was seen by many as saying something good, something important about America itself.”

The book’s message had underlying liberal values and established Lee as a proponent of fairness among races—an uncommon belief in the South at the time of its release.

The New York Times described “To Kill a Mockingbird” as a “stark morality tale of a righteous Southern lawyer who stands firm against racism and mob rule struck a chord with Americans, many of them becoming aware of the civil rights movement for the first time.”
