It took less than an hour to raise more than $100,000 to change the lives of some Brooklyn schoolchildren.

Brandon Stanton, the photographer behind the widely popular “Humans of New York” blog, launched a fundraising campaign Thursday to help send a group of underprivileged students from Mott Hall Bridges Academy in Brownsville on a trip to see Harvard University.

He was hoping to raise $100,000 by Feb. 5, enough to fund the program for three years — but people have more than doubled the goal.

He shared a link to the IndieGoGo page on the HONY Facebook page — which has more than 11 million followers — and strangers stepped up, mostly making small donations between $1 and $25. All of that quickly ballooned to more than $220,000.

Stanton met a young boy from the school on Monday, who told him his principal, Ms. Lopez, was the most influential person in his life. This moved Stanton to want to get involved with helping the children.

“When we get in trouble, she doesn’t suspend us,” the young boy with a black winter jacket said. “She calls us to her office and explains to us how society was built down around us. And she tells us that each time somebody fails out of school, a new jail cell gets built.”

“And one time she made every student stand up, one at a time, and she told each one of us that we matter,” he added.

Turns out that’s not all Ms. Lopez does to make her students feel loved.

“We don’t call the children ‘students,’ we call them ‘scholars,’” she explained to Stanton, who went to the school Wednesday to meet her.

His post, which already had more than 60,000 likes, detailed his meeting with Lopez and their brainstorming session about how the HONY community could help the school.

He explained to his followers that many of the kids at the school have “very limited mobility” and “many have never left the city.”

Their idea to take the sixth-grade class on a trip to Harvard was a way to get them unstuck.

“I want every child who enters my school to know that they can go anywhere, and that they do belong,” Lopez said.

The trip, which would include all the transportation and accommodations, would cost about $30,000.

Stanton likely anticipated a big response to this fundraiser, as he has had many successful campaigns to help average New Yorkers since he started his blog in 2010.

“Each additional $30,000 raised will provide another class of students with their own trip,” he wrote on the IndieGoGo site.

“So let’s really hit it out of the park for these kids.”
