When Toni Morrison received her Nobel Prize in Literature in 1993, her remarks began with a reflection on the phrase once upon a time. In her signature, measured cadence, Morrison told the Swedish Academy she believed these were some of the first words we remember from our childhoods.

Exactly 100 years ago today, Chicago was in the throes of a brutal heat wave. Thousands flocked to the beaches lining Lake Michigan for some relief. Among them: a group of black boys that included 17-year-old Eugene Williams. Eugene, who was on a raft, inadvertently drifted over the invisible line that separated the black and white sections of the 29^th St Beach. One white beachgoer, insulted, began throwing rocks at the black kids. Eugene Williams slipped off his raft and drowned.

Because of her food journalism, the food world has been well aware of Samin Nosrat for several years. But she became a household name when two things happened: First, her book, Salt, Fat, Acid, Heat: Mastering the Elements of Good Cooking, became a runaway bestseller. The book explores the mysteries of cooking for the home chef and garnered just about every award a cookbook could get.

Poet Kevin Young says there are so many different kinds of poetry, even people who think they hate it should reassess. "I think of [poetry] more like music," Young told me last year. "Like, if someone said, 'I don't like any music,' I would be like 'Who are you? I don't understand.' They haven't found the right music to me, then."

Ebony magazine was more than a publication — to black America, it was a public trust. It held a place of prominence in millions of African-American households whose members did not otherwise see themselves in the mainstream media. So back in 2015, when Johnson Publishing Company announced it was spinning off its flagship magazine, Ebony, and also its news magazine sibling, Jet, people knew something was up.

Today, ethnic studies is an accepted part of academia. Many if not most college students have taken a course or two. But 50 years ago, studying the history and culture of any people who were not white and Western was considered radical. Then came the longest student strike in U.S. history, at San Francisco State College, which changed everything.

The groundwork was laid for the strike a couple of years before, when black students organized to press for a black studies department and the admission of more black students.

The value of civility is one of the few things Americans can all agree on — right? That's the common assumption. And yet it's an assumption that depends on everyone thinking they're a full member of the community.

But what about when they aren't?

John Carlos and Tommie Smith went to the 1968 Summer Olympics in Mexico City with a plan: If they won medals, they would stage a protest against racism and injustice on the world stage.

Smith and Carlos both attended San Jose State University, where black athletes had been quietly meeting to discuss whether they would even go to the Olympics.

Apartheid-era South Africa had been given permission to compete in the games, but with a threatened boycott by some of the Americans, the invitation was withdrawn and the boycott called off.
