A portion of the slurry wall was deliberately left exposed in the Foundation Hall of the National September 11 Memorial Museum.
Some of the heroes of Sept. 11, 2001, performed their lifesaving work at the World Trade Center many years before the attack.
Arturo Lamberto Ressi di Cervia, who died last month at 72, supervised the construction of the slurry wall around the trade center foundation in the 1960s. When the towers collapsed in 2001, and the wall began to strain under almost unthinkable pressures from the surrounding water table, his work paid off.
The wall held.
Because the slurry wall held, the 70-foot-deep foundation did not fill with groundwater. And because of that, the PATH tubes were not submerged. And because of that, the subway tunnels below the PATH tubes were not inundated.
How much worse could Sept. 11 have been? Imagine if Hurricane Sandy had followed the terrorist attack by a few hours.
Mr. Ressi’s supervision of the slurry wall construction “may have helped prevent the Hudson River from flooding parts of Lower Manhattan,” said George J. Tamaro, a former staff engineer at the Port Authority of New York and New Jersey who was closely involved with the construction of the trade center.
The once-lowly wall became a symbol of resilience in the months and years after the attack. Its importance was so widely acknowledged that a portion wasdeliberately left exposed in the colossal Foundation Hall of the National September 11 Memorial Museum, which is to open next year.
Of course, that wasn’t what Mr. Ressi set out to build in 1967, when he arrived in New York at age 27, just three years out of the University of Bologna, Italy, from which he held a doctorate in engineering.
He worked for Icanda, an Italian-Canadian contractor that specialized in slurry walls. First, trenches would be dug down to bedrock; about 70 feet below street level, in the case of the trade center.
Slurry — a muddy soup of water and bentonite clay — would be pumped into the trench to keep the sides from closing up until a giant cage of steel rebar could be lowered into the trench, after which concrete would be pumped in.
The concrete, heavy enough to displace the slurry, would harden into a wall that no one would actually see until it was completed all around, after which excavation could begin within the 11-acre area enclosed by the wall.
Without such a retaining wall, it would have been impossible to excavate the trade center site, much of which was on spongy landfill dating to the 18th century. And conventional foundation wall construction was ruled out because of the many underground obstacles, from ships’ ballast to the PATH tubes.
Before Icanda could begin, the Port Authority and City Hall had to work out differences over the development of the trade center. (Sound familiar?) That was when Mr. Ressi met a singer named Carol Marie Gerdts, and fell in love. “I basically was twiddling my thumbs for months,” he told my colleague James Glanz in a 2003 interview, “and as a result I got married.”
All else was stress. Icanda had no experience dealing with New York’s construction trade unions. It was employing a technique untried at such a scale, using jury-rigged tools, on a site that brimmed with uncharted obstacles and unhappy surprises, like a sudden 50-foot drop in the bedrock level where asmall valley had been carved by retreating glaciers.
Crews worked around the clock. When a crisis developed at 3 a.m., Mr. Ressi thought nothing of telephoning Mr. Tamaro at home. “If I wasn’t sleeping, why should he?” was his philosophy. “We would get a quick decision.”
Mr. Ressi prided himself in saying the main perimeter wall construction was finished in nine months, “pretty much on schedule.”
Thirty-five years later, in 2002, the architect Daniel Libeskind drew the world’s attention to the symbolic significance of the wall, when he proposed its preservation and exposure as part of the redevelopment of the trade center.
“My first experience at ground zero was going down to bedrock and being viscerally transfixed,” he said this week. “I realized this is not only about unimaginable destruction but about the power of resurgence.”
Mr. Libeskind recalled a “very emotional” conversation with Mr. Ressi in which he described his plan to expose the slurry wall. “I think he instantly understood why it was important to do that,” Mr. Libeskind said.
Indeed, he did. In their 2003 conversation, Mr. Glanz mentioned to Mr. Ressi that some engineers had expressed reservations about the idea.
“Oh, no,” Mr. Ressi said. “I was instead so pleased that that was the chosen scheme because I think it is — well, not only do I like the architecture of it, but I also like the idea of having that space open again. Although I promise you, I never thought I would have seen that wall again in my life.”
Maharaja Duleep Singh married twice, first to Bamba Muller and then to Ada Douglas Wetherill. He had eight children in total, six from his first marriage to Bamba:
He also had two children from his second marriage to Ada Douglas Wetherill:
All the eight children died without legitimate issue, ending the direct line of the Sikh Royalty.
Duleep Singh was much admired by Queen Victoria (Britain Queen, between (1838-1901), who is reported to have written of the Punjabi Maharajah: "Those eyes and those teeth are too beautiful". The Queen was godmother to several of his children.
Singh is considered as Britain's first Sikh settler, having been exiled to its shores in 1854, after being dethroned and having his country annexed by the East India Company in 1849.












While in exile, he sought to learn more about Sikhism and was eager to return to India. Though previous efforts were thwarted by his handlers, he re-established contact with his cousin Sardar Thakar Singh Sandhawalia, who on 28 September 1884, left Amritsar for England along with his sons Narinder Singh and Gurdit Singh and a Sikh Granthi (priest),Pratap Singh Giani. He also brought a list of properties held by Dalip Singh in India. All this renewed his connection with Sikhism.
The British Government decided in 1886 against his return to India or his re-embracing Sikhism. Despite protests from the India Office, he set sail for 'home' on 30 March 1886. However, he was intercepted and arrested in Aden, where the writ of the Governor General of India began. He could not be stopped from an informal re-conversion ceremony in Aden, far less grand and symbolic than it would have been in India, done by emissaries sent by Sardar Thakar Singh Sandhawalia, who was earlier planning the Pahaul ceremony at Bombay. Dalip was forced to return to Europe.
Duleep Singh died in Paris in 1893 at the age of 55, having seen India after the age of fifteen only during two brief, tightly-controlled visits in 1860 (to bring his mother to England) and in 1863 (to scatter his mother's ashes).

The same scene will transform into lush green agricultural field to give you a big relief after you have the city peripheries. But it continues to effect your memory for the dirty scene seen a while ago. I even cannot understand the difficult situation of a woman or a invalid person who has no where to go in the broad day light.
The Lok Sabha passed a long-awaited bill to ban manual scavenging--the clearing of human waste by hand from toilets--on Friday which outlaws employment of scavengers and will provide retraining and help for their families.
With more than 600 million people lacking even basic toilet facilities and being forced to defecate in open,
A 2011 survey by the Central Pollution Control Board showed that just 160 out of nearly 8,000 towns had sewerage systems and sewage treatment plants.
Workers stripped down to their underpants and equipped with just a hoe and a wooden bar can still routinely be seen clambering into the depths of septic tanks and sewers.
Rural development minister Jairam Ramesh's comment that "there are more temples in the country than toilets" had led to a controversy last year. He had said, "India has a godliness surplus and cleanliness deficit."
It is shame that even in 21st century, we continue to live in 18th. Why it took more than six decades to pass such a bill and stamp out the shame in an independent sovereign country.
