The little park outside the Stonewall Inn in Manhattan, the site of a major turning point in the gay rights movement nearly 50 years ago, became a permanent beacon last year when it was named a national historic monument.

But those who remember the night Stonewall patrons defiantly clashed with the police have dwindled over the years. Their stories risk going untold.

On Sunday, Senator Chuck Schumer of New York announced a $1 million grant from Google.org, the internet giant’s philanthropic wing, to The Lesbian, Gay, Bisexual & Transgender Community Center, to start a project preserving the oral histories and human experiences of the people who stood up and fought back during those tense days in 1969. The initiative is in conjunction with the National Park Foundation, which will create an educational curriculum for students and a digital platform intended to magnify the reach of the monument beyond the small triangle of parkland in the West Village.

“The purpose is to spread the word about the Stonewall uprising and the progress we have made as well as the distance we have to go,” Mr. Schumer said. “And it sends a great message to Washington, especially in these times: We celebrate our diversity and cherish it, we don’t shrink from it and we don’t fear it.”
