After Occupy faded from the headlines Mr. Pellagatti became a guide for a bus tour company. He is a member of the Guides Association of New York, he said, and licensed by the city’s Department of Consumer Affairs. Recently, he decided to start the Occupy tour, determined to tell the story of the movement and convinced that its importance would attract participants.

“We were a physical embodiment of poverty living in a modern-day Hooverville, showing the world that they had to pay attention,” he told the British visitors: a lecturer, a Ph.D. candidate and six undergraduates from the University of London studying protest movements.

The stop at Zuccotti Park was perhaps the strongest part of the tour, with Mr. Pellagatti drawing from the sort of personal experiences that few other guides would be likely to cite. He pointed out where the park’s library, kitchen and recycling center had been. He curled up on a granite bench to show where he had slept. And he described certain well-known visitors to the park, like the Rev. Jesse Jackson, who linked arms one night with a group of protesters to stop the police from removing a tent there; and Kanye West, who Mr. Pellagatti said once mistakenly interrupted a meditation session in the park by walking through a group of people sitting quietly in a circle.

Mr. Pellagatti acknowledged the darker side of the park, saying that drug use and sexual assaults had taken place there, though they did not define the movement. And he offered opinions on crucial but overlooked moments in Occupy’s history. One came during a rainstorm on the protest’s sixth day, Mr. Pellagatti said, when the police had forbidden the use of umbrellas, tents or tarps secured to trees, and protesters took turns holding up a plastic sheet as others huddled underneath “That’s when we went from being a bunch of strangers sleeping in a park to a movement that later spread to 82 countries,” Mr. Pellagatti told the tour members.
