An online slideshow and story from DNAinfo.com reveals some of the large artifacts that are heading for the National September 11 Memorial & Museum in the fall.

According to DNAinfo’s Julie Shapiro, “The items include a 47,000-pound piece of the North Tower’s antenna and a 10,000-pound elevator motor that once propelled workers up into the skyscrapers.”

The 9/11 Memorial will open September 11, 2011, and the museum will open in 2012.

MyGoodDeed, a 9/11 non-profit organization, announced its plans Wednesday to organize the largest day of service in U.S. history on Sept. 11, 2011 in honor and commemoration of the 10th anniversary of the attacks, according to PR Newswire.  The announcement was made during the National Conference on Volunteering and Service in New York.

MyGoodDeed spearheaded the effort to establish Sept. 11 as an annual National Day of Service and Remembrance, which was signed into law by President Obama in April 2009.  The National September 11 Memorial & Museum is working with MyGoodDeed towards this day, along with numerous other non-profit organizations.

Approximately $1 million has already been raised, through private grants and federal support, to encourage the September 11 National Day of Service and Remembrance.  It was also announced that a special website will be launched to help organizations sign up for the day of service.  The goal is to enroll as many as 100,000 organizations before the 10th anniversary.

Volunteer service projects, open to the public, will be organized for September 10-11, 2010, in New York, Washington, D.C., Boston and Philadelphia.  Regional affiliates hope to encourage and mobilize volunteers through organized service projects in remembrance of the 9/11 victims.  Projects will occur in cities across the country and featured on HandsOnNetwork.org, and service opportunities will be posted on 911dayofservice.org.

The 9/11 Memorial will open at the World Trade Center site on Sept. 11, 2011, and the museum will open one year later, with service as an important element in its exhibits.

The first director of the World Trade Center and the man behind the twin towers' original construction recalled picking the architect for what were once the world's tallest buildings and his ongoing relationship with the Frenchman who walked a high wire strung between the two skyscrapers.

The WTC's first director, Guy Tozzoli, chatted Monday with museum staff of the National September 11 Memorial & Museum. He was hired in 1962 by then-named Port Authority of New York to head the development, construction and management of the World Trade Center, a complex aimed to revitalize lower Manhattan.  He was responsible for the entire project and chose architect Minoru Yamasaki.

Yamasaki originally designed several 80-story towers for the site, but Tozzoli was persistent in increasing the design to feature twin 110-story buildings.  Tozzoli said he has the tendency to keep making things bigger, even now.

He now serves as president of the World Trade Center Association, an organization he founded in 1970 to connect countries through economic activity.  At its inception, the association had only 15 participants from 15 countries.  Today, there are 325 "World Trade Centers" in cites across 92 countries.  In 1999, Tozzoli was nominated by the South Korean and North Korean governments and was accepted as a candidate for the Nobel Peace Prize for his work.

“I like what I do,” said Tozzoli, who at the age of 88 still heads the organization.

Tozzoli oversaw the World Trade Center in New York from its construction in the 1960's until its destruction on Sept. 11, 2001.  His office was located on the 77th floor of the North tower, and he enjoyed his time working there.  "I loved it," he said.

When speaking about the towers, Tozzoli said, “Windows on the World was my favorite place,” a restaurant he hopes to see recreated in one of the future towers.

Tozzoli also joked about his relationship with Philippe Petit, the French high-wire artist who “danced” across a tightrope between the twin towers in 1974.  The pair, who are now friends, speak at public lectures together.

“It’s really fun,” said Tozzoli, who loves sharing stories like Petit's high-wire act. “They become part of you," he said, still remembering the day mountain-climber George Willig scaled the 110 stories in 1977.

On Sept. 11, Tozzoli watch the towers he built burn and collapse while he was arriving late to work from the Holland Tunnel.

“I wanted to go down and be with the people,” he recalled.  But he was turned away after showing a police officer his credentials.  "He said, 'I don't care if you're the pope.'"

Now, Tozzoli said he wants “to help people do it all over again” and he said he's “looking forward” to visiting the 9/11 Memorial when it is completed next year.

Tozzoli also hopes to still be around when the new towers are finished.  He joked, "I'm older than God."

The above photographs, taken by New Yorker Hiro Oshima, show the images he saw when he evacuated his lower Manhattan residence on Sept. 11.  The images are now part of the National September 11 Memorial & Museum’s Make History initiative.

Make History is a collective telling of the events of 9/11 through the eyes of those who experienced it, both at the attack sites and around the world.

Oshima has contributed many of the images he captured on Sept. 11 to the Make History archive.  Oshima, who witnessed the collapse of the towers, had moved to lower Manhattan in 1999.  He used to consider Windows on the World, atop the World Trade Center, his “neighborhood bar.”

Oshima, like many others, was evacuated from his building on 9/11.  His photographs show his movement from lower Manhattan to Battery Park and then onto New Jersey.  After Sept. 11, Oshima moved in with his college roommate in the East Village.  It wasn’t until December that his building was accessible.

The Make History archive currently contains more than 1,000 photographs and 300 stories.  Visitors to the site can upload their own pictures, videos and stories about 9/11 and the impact it had globally.

Make History has been recently recognized by an award academy that notes great achievements in the online community.

Since construction officially began on the National September 11 Memorial and Museum in 2006, the World Trade Center site has transformed.

Where one used to see mostly mounds of dirt and tons of construction equipment, now two structurally defined Memorial pools are visible along with construction on One World Trade Center, the skyscraper commonly known as the Freedom Tower.

The photograph on the left, above, shows an aerial view of 9/11 Memorial construction in August 2007.  At that time, 580 metric tons of jumbo steel l-beams, to be used for the memorial and museum, had just arrived at the Port of Savannah, Ga., after a 4,000-mile journey from Luxembourg in central Europe.  The steel didn’t officially arrive on site until later that year.  More than 8,000 tons of steel are being used to construct the 9/11 Memorial and 100 percent of the steel has since been installed at the site.

The photograph on the right, taken last month by resident photographer Joe Woolhead, shows the highly anticipated construction of the North and South memorial pools, where dark granite panels are currently being placed.  The pools are about an acre in size, and they are situated within the footprints of the original towers.  Ten large pumps will create 40 pounds of pressure to circulate 52,000 gallons of water per minute for the artificial waterfalls.  These will be the largest man-made waterfalls in the country.

The 9/11 Memorial will open Sept. 11, 2011.

The asking price for David Rohde's release was $25 million.

Tomorrow evening, two-time Pulitzer prize winner Rohde will discuss his seven-month captivity with the Taliban as part of the "9/11, Today and Tomorrow" Speakers Series.  The New York Times reporter is set to talk about the Taliban mini-state currently training suicide attackers and roadside bomb-makers who kill Afghan, American and Pakistani soldiers.

The "Escaping the Taliban" event featuring Rohde is Wednesday, June 23 at 6:30 p.m. at the 9/11 Memorial Preview Site, 20 Vesey St.  Doors open at 6 p.m.

Rohde has covered conflicts in Afghanistan, Bosnia and many other countries. From November 2008 to June 2009, he was held captive by the Taliban until his eventual escape. He is also the co-author of the forthcoming book “A Rope and A Prayer: The Story of A Kidnapping.”  A five-part series that Rohde wrote on his captivity and escape for The New York Times was recently awarded the 2009 George Polk Award for foreign reporting.

Due to space limitations, RSVP is recommended to guarantee a seat up to 15 minutes before programming begins.  A suggested donation of $10 per person will help support ongoing programming.

After watching the Sept. 11 attacks unfold, Michael Ragsdale started a personal campaign to collect fliers, cards and brochures that marked the day’s events and the subsequent months.

“I decided to collect stuff that I felt would be ignored,” he said.

Seeing the North Tower on fire, Ragsdale said he knew something unprecedented was happening and sensed the towers may not exist much longer.  He quickly went down to the site, feeling compelled to grab any memorabilia.  He took a couple hundred World Trade Center brochures shortly before the towers fell.

Ragsdale, who has been an autograph collector since 1997, began collecting this 9/11 ephemera over the 14 months following the attacks.

“I had the opportunity to do it, so I did it,” he said.

Ragsdale collected pieces such as event fliers that organizations handed out on the streets.  One flier read: “Protest Fire Bombings Against Arab Stores."  He also collected warning signs posted around ground zero and the World Trade Center site, including one that said, “Crime Scene Search Area: Stop."

He said the most shocking piece he collected was a sign he got from around ground zero that read “Warning: Poison.”

Ragsdale's ephemera collection was acquired by the National September 11 Memorial & Museum for display in future exhibitions. The collection has more than 4,100 pieces.  These collected items are to become part of the showcases highlighting the aftermath of the attacks.

This photo, taken of a man making a call the first day the New York Stock Exchange opened after the Sept. 11 attacks, was captured by Harry Zernike. It can now be viewed through the National September 11 Memorial & Museum’s Make History initiative.

Following the events of 9/11, major communication lines in lower Manhattan were down, making it impossible for business to run as usual.  The New York Stock Exchange reopened September 17 after almost a week of inactivity, as did many other downtown businesses.

Make History is a collective telling of the events of 9/11 through the eyes of those who experienced it, both at the attack sites and around the world.  The archive currently contains more than 1,000 photographs and 300 stories.  Visitors to the site can upload their own pictures, videos and stories about 9/11 events and the impact it had globally.

Since construction began on the National September 11 Memorial & Museum, there’s been one man who’s seen every angle, view and development.

Joe Woolhead, the photographer capturing the World Trade Center site and memorial and museum’s construction, is working together with Silverstein Properties to document the progress.

Born and raised in Dublin, Woolhead now works and lives in New York City with his wife and son.  He became a professional photographer on Sept. 11 after capturing the events of that day and the subsequent days.  His shots were published all over the world.  The event led to many more opportunities for Woolhead, including work with the premier photography agency, Sipa Press.

In May 2004, Woolhead began to work with Silverstein Properties.  Now, he works at the World Trade Center site photographing the ongoing construction.  Due to his work at the site, Woolhead has invested more of his time in architectural photography.

Woolhead’s photos have been featured in The New York Times, Time, Town & Country, Esquire, Gotham, New York Post, Daily News, and Wall Street Journal, along with many other national and international publications.
