WINCHENDON – Twenty-five years after the Sept. 11 terrorist attacks, Winchendon resident James Pelletier is expanding his longtime remembrance effort, with public-access television stations across Massachusetts set to broadcast a recording of the names of the 2,977 victims.

Stations serving Athol and Orange, Ashburnham and Westminster, Dracut, Fall River, Fitchburg, Gardner, Greenfield, Hubbardston, Leominster, Lunenburg, Saugus and Winchendon are expected to air the nearly three-hour recording on Sept. 11. Pelletier has asked stations to begin at 8:46 a.m., the time the first plane struck the World Trade Center, although exact start times may vary slightly by station.

Pelletier, an artist and poet, volunteered at Ground Zero following the attacks and later founded the all-volunteer organization Remember to Remember Sept. 11, which focuses on honoring those who died that day.

“Dignity is more powerful than destruction,” Pelletier said, describing the core belief behind the group’s work.

The recording project began in 2002, when Pelletier worked with the New York unit of Recording for the Blind & Dyslexic, now known as Learning Ally, to record the names of World Trade Center victims. It was later expanded to include those killed at the Pentagon and aboard the hijacked flights.

The recording has been presented as part of Sept. 11 remembrance efforts over the years. Pelletier said it was originally spread across about a dozen CDs that had to be played individually before later being condensed onto a single MP3 disc. His goal is to eventually have every public-access television station in Massachusetts air the program each Sept. 11.

“The reason is simply, the technology now exists to share it with the world,” Pelletier said.

For this year’s anniversary, he said he worked with IBM to make the recording available through its streaming service.

Pelletier also contacted AOTV about broadcasting the program locally. AOTV Executive Director Liz Walber said the station typically airs Sept. 11 remembrance programming and agreed to air the recording on both its television and radio stations.

Walber said Pelletier was having difficulty making the recording available in a format other public access stations could download. She said she took the existing audio file and added an image to create a video version for television. AOTV is hosting the downloadable file through its Google Drive for other stations to use.

“Because it was locally made, because we got to talk to James, it was a no-brainer for us to help them out and also put it up,” Walber said.

Pelletier’s remembrance efforts also include a new presentation of his poem, “Downtown Lower Manhattan,” through Learning Ally. He wrote the poem after returning from his volunteer work at Ground Zero.

“It’s a love poem about a place that is very deep in my heart and very deep in my soul,” he said.

Pelletier worked in the Wall Street community in the 1970s and was involved with two projects with the World Trade Center. He also had an exhibition of his sculptures in Battery Park in 1978.

According to Pelletier, the poem has received praise from the late former President Jimmy Carter and the Office of the Dalai Lama.

For the 25th anniversary, Learning Ally volunteer Sheila Kerwin narrated a new presentation of the poem, which Pelletier said makes it available to a wider audience. The presentation has been added to the organization’s Audiobook Solution library, and an accessible recording is also available online.

Pelletier said he wants people who remember the Sept. 11 attacks to share their experiences with those who were too young to remember them or were not yet born.

“I think that oral tradition is being lost,” he said. “I think people are not taking the time to share their memories with people under the age of 30.”

Pelletier also referenced an Irish belief that a person is not forgotten as long as someone continues to speak their name.

“And so having the victims’ names read out loud is a way of keeping them alive,” Pelletier said.
