Billionaire donates $7.5 million to repair Washington Monument

Daniel Gach and Emma Cardini from WJE rappel down the Washington Monument to assess earthquake damageDavid Rubenstein, the billionaire co-founder of private equity company The Carlyle Group and an avid history buff, has donated $7.5 million to the Trust for the National Mall to repair the Washington Monument. In December Congress allocated $7.5 million to fund the repair on the condition that the National Park Service raise matching private funds. Rubenstein’s donation thus not only grants the restoration efforts a hefty sum in itself, but also assures the Congressional funding.

The 555-foot obelisk, built in 1884 to honor the first president of the United States, was damaged by the 5.8 magnitude earthquake that struck the capital on August 23, 2011. Early assessments found a large four-foot-long, one-inch-wide crack and a number of smaller cracks in the monument, so for safety reasons the monument was immediately closed to the public. Later more detailed assessments found the damage was even worse than they first realized.

The $15 million will go to repairing all of the direct earthquake damage. It’s not enough, however, to cover some of the other issues plaguing the monument, like extensive water damage to the interior from the cracks in the marble and lost mortar at the peak of the obelisk. Some of the marble panels up top were cracked all the way through. The monument also needs structural reinforcement to protect the tallest obelisk in the world against future freak earthquakes, so here’s hoping there are more billionaire history buffs lying around somewhere.

The Washington Monument continues to be closed to the public and it looks like it will remain closed for the next two years. The Park Service is taking bids from contractors now with the aim of starting repair work by the end of August. They expect the repair to take 10 months to a year to complete.

The National Park Service website has an incredible photo gallery of the earthquake damage and the assessments done by civil engineers from the Difficult Access Team of contractors Wiss, Janney, Elstner Associates, Inc. (WJE).

The Difficult Access Team is my new obsession. The WJE team did preliminary damage assessments of the Washington Monument, Jefferson Memorial and Lincoln Memorial the day after the earthquake. That work was done visually — by helicopter for the top of the obelisk — but they had to return to the Washington Monument to do an in depth investigation by rappelling off the top. These are engineers, mind you. They could spend their lives in an office drafting things, but instead they badassedly rappel down a 555-foot marble needle. Two of the four are women, so yay sisterhood! Here’s one of those women, engineer Emma Cardini, starting her descent on September 28, 2011:

Here’s more dizzying video taken from the helmet of WJE engineer Erik Stohn:

If you’re wondering why they had to rappel this time instead of using a helicopter or scaffolding, according to NPS Acting Chief of Resource Management Jennifer Talken-Spaulding a detailed damaged assessment requires hands-on (literally) work. You have to be able to touch the stone, tap it, listen to the sounds it makes, see the condition of the mortar and marble. They also had to remove spalls, chunks of stone that have come loose and could pose a serious hazard to people on the ground. You have to do that by hand. Scaffolding takes a long time to build, and they wanted a thorough assessment of the damage before the cold winter set in.

This is what it looked like at the 500-foot level observatory when the earthquake hit. The shaking starts at 1:45, but watch the whole thing to see the security guard just hanging out and tourists walking around casually before things suddenly get hairy.

National Park scores deluxe pre-Civil War bathroom

Dunleith bathtub, shower and commode unitThe National Park Service has carefully dismantled and removed an 1850’s bathroom from the Dunleith Historical Inn in Natchez, Mississippi. One of only 20 antique bathrooms remaining in the United States, the Dunleith lavatory had hot and cold running water, a bathtub, a shower and a commode that were all part of a single large piece of furniture. The shower wouldn’t be out of place in a luxury home today; it has a 10-inch rain showerhead. An immense 400-pound zinc-lined cistern once contained the hot water for the system. (There was also a separate wash table with a marble sink which isn’t in the bathroom anymore, but the NPS hope to secure nonetheless to complete the set.)

The bathroom is thought to have been installed in 1859 by Alfred Vidal Davis who bought the Greek revival mansion that year. When the National Park Service workers were removing the bathroom, they found a packing slip from New Orleans plumbing company Price & Coulon. NPS historian Jeff Mansell believes the entire system was available for purchase from a catalog, hence the packing slip.

Ten-inch rain showerheadIt was installed on the third floor at the top of a forbiddingly steep staircase. Pipes carried water from the laundry room on the first floor where it was heated by boiler up to cisterns in the attic. When someone turned on the faucets or flushed the toilet, the cisterns drained down to the third floor. The toilet waste would then be piped to a septic tank that was also connected to the more traditional outhouses on the property.

That inconvenient third floor location saved its life, because bathrooms are gutted all the time but this one was so out of the way that subsequent owners never bothered renovating it. For the past decade it’s been used as a storage room. Now the Dunleith Historical Inn is renovating the space to make more room for paying guests. Recognizing the rarity and importance of the bathroom, they decided to donate the fixtures to the National Park Service.

Removing the cisternThe NPS accepted with alacrity, but removing the fixtures was an engineering challenge (LiveScience has a photo gallery of the process). Construction crews had to remove the commode, shower and bathtub separately, then build a ramp and use a forklift to get that 400-pound cistern out of the house.

For now the parts will be stored, but the NPS plans to install them in another Greek revival antebellum mansion: Melrose, a National Park Service property that dates to the 1840s. Melrose had some sort of washroom facility in the 1850s, but only the pipes remain so we can’t know what kind of fixtures were originally installed. The Dunleith bathroom will in all likelihood be installed in one of two dressing rooms at Melrose that are currently off-limit to guests.

Once the bathroom is installed, Mansell said, the room will be open for public viewing. He said he believes people will be surprised at the plumbing technology that was used in the bathroom.

“I don’t think (people) think of systems like this existing in the 19th century,” he said. […]

[John Holyoak, manager of Dunleith Historical Inn,] said moving the bathroom’s contents from Dunleith will allow the rare technology to be preserved and displayed.

“If we leave that bathroom where it is, no one will ever see it,” he said. “The benefit of having it moved is that it will be set up as a public display and tourists will be able to see something extremely unique.”

Sign me up. I have had a passion for historical bathrooms since I was a little kid squatting on the Roman latrines at Ostia.

Leonardo da Vinci live at a movie theater near you!

Okay, so you weren’t able to get to England or sell your kidney to buy a scalped ticket for the sold out blockbuster Leonardo da Vinci: Painter at the Court of Milan exhibition at London’s National Gallery. For the many of us all over the world in that sad boat, we will have to content ourselves with a viewing of an HD documentary on the exhibit: Leonardo Live (which isn’t live for us but was broadcast live originally).

Captured live on November 8, 2011, LEONARDO LIVE provides a virtual walk-through of the exhibit, with exclusive commentary from scholars and curators. Hosted by highly respected art historian Tim Marlow and presenter Mariella Frostrup, the exhibition brings together the largest number of da Vinci’s rare surviving painting and some international loans. While numerous exhibitions have looked at da Vinci as an inventor, scientist or draughtsman, this is the first to be dedicated to his aims and techniques as a painter.

When I last blogged about this, the screening dates hadn’t been published yet. Now they have and you can buy your tickets in advance. It opens in 450 theaters around the country on February 16. Since most of the screenings are a one-night-one-showing-only event, I suggest you book early. You can plug your zip code into this site to get a listing and map of the theaters nearest to you that are showing the movie.

For some fascinating background on the Herculean effort it took to put together this unprecedented exhibit, read this article from the Telegraph. It took five years from idea to exhibition, and it would never have happened if Queen Elizabeth II hadn’t agreed up front to allow Luke Syson, the National Gallery’s curator of Italian paintings before 1500, to offer loans of important Leonardo drawings from the Royal Collection in return for loans of Leonardo paintings.

So Syson started by negotiating the loan of the Lady with an Ermine from the Czartoryski Foundation in Cracow. Next he asked his colleagues at the Louvre for La Belle Ferronnière. With two such stunning portraits secured for the show, it would have been hard for Veneranda Biblioteca Ambrosiana in Milan to turn down his request for Leonardo’s Portrait of a Musician, because with the addition of the two versions of the Virgin of the Rocks it looked like every surviving picture painted by Leonardo in Milan would be in the show.

Every picture he painted in Milan (the frescoes in the Castello Sforzesco and The Last Supper excluded, of course, on account of they’re attached to walls) is fully half the total number of the Leonardo paintings known to survive.

New evidence of mass graves found at Treblinka

Treblinka on fire during prisoner revolt of August 2, 1943A team of archaeologists from the University of Birmingham have discovered new evidence of huge mass graves on the former site of the Nazi extermination camp Treblinka.

Since the Nazis razed the camp in November of 1943 after a prisoner revolt, leaving little visible evidence of the 800,000+ Jews they’d slaughtered in just over a year of operation, Holocaust deniers have claimed that Treblinka wasn’t a death camp at all, but rather a transit station where prisoners were sorted before being shipped off to other labor camps. (Interestingly, that’s just what the SS told new arrivals before making them undress and sending them to the “showers” for “delousing.”)

This is the first coordinated scientific attempt to locate graves at Treblinka. Led by forensic archaeologist Caroline Sturdy Colls, the research team used ground-penetrating radar and aerial and satellite imagery to look for burial sites without breaking ground, out of respect for Jewish Halacha law which forbids disturbing burial sites.

Bomb crater exposes buried bones, Treblinka, 1945Sturdy Colls said: “All the history books state that Treblinka was destroyed by the Nazis but the survey has demonstrated that simply isn’t the case.”

She added: “I’ve identified a number of buried pits using geophysical techniques. These are considerable in size, and very deep, one in particular is 26 by 17 metres.”

Treblinka excavator digging mass grave pitsDug by an enormous excavator from the quarry at the nearby Treblinka I forced labour camp, each of these large pits are thought to contain the charred remains of thousands of bodies. Some of the pits were used for burial, others as cremation pits. In March 1943, Heinrich Himmler visited the camp and ordered that all the bodies be cremated. The burial pits were opened and the corpses burned on cremation grates built out of railway tracks. There are pictures extant of the resulting ash heaps.

BBC Radio 4 will air a program following the Colls’ work at Treblinka. The Hidden Graves of the Holocaust first airs on Monday, January 23 at 8:00 PM.

A more personal witness to the horrors of the Holocaust can be found in a remarkable book recently published by the Auschwitz Memorial and Museum: The Sketchbook from Auschwitz. In 1947, Józef Odi, a former prisoner who was working as a watchman on the Auschwitz grounds, found 32 sketches on 22 pages rolled into a bottle and hidden in the foundations of a barracks near the gas chambers and crematoria.

These incredible works of art, beautiful and horrifying in equal measure, are the only drawings made in Birkenau to depict the extermination of Jews. They are signed with the initials MM, so we don’t even know the name of the artist. We know from some of the depictions that they were made in 1943 and that the artist was immensely courageous to make these detailed drawings recording the systematic mass-murder of Jews, including badge numbers of functionary prisoners, license plates of trucks and train cars.

This is the first time all of the MM sketches have been published.

Lost Darwin fossil slides found in British archive

Fossil wood Darwin collected on the Island of Chiloe, Chile in 1834University of London paleontologist Dr. Howard Falcon-Lang was looking through an old cabinet in the British Geological Survey archives for some carboniferous fossil-wood specimens. He opened a drawer labeled “unregistered fossil plants” and found hundreds of glass slides of thin, polished fossil plant sections. He fished out a slide and examined it with a flashlight, finding to his great shock the signature of one C. Darwin, Esq. That slide turned out to be a piece of fossilized wood Darwin had collected during his now-iconic voyage on the HMS Beagle in 1834.

The cabinet contained 314 slides of fossils collected by botanist Joseph Dalton Hooker, Darwin’s best friend who had helped him classify the specimens he had gathered in South America and the Galápagos Islands. Several other slides bear Darwin’s name, and experts think that some of the unlabeled specimens were also prepared by Darwin.

Fossil tree at Craigleith Quarry in Edinburgh, slide by William Nicol, 1831The collection also includes specimens collected by Hooker himself on his travels, pieces from the private cabinet of Reverend John Stevens Henslow, Darwin’s Cambridge mentor and Hooker’s father-in-law, and some very early rock sections made by pioneering geologist William Nicol in the late 1820s. Nicol first devised the technique of affixing a crystal or rock section to a slide then grinding it down until it was thin enough to view through a microscope just a few years earlier in 1815. Some of these slides are huge compared to their descendants today, six inches long and a tenth of an inch thick.

Cones of giant club mosses found in a coal measure by Hooker, 1846J.D. Hooker had first assembled the slide collection when he worked for the British Geological Survey from February 1846 to October 1847. At that time the Survey didn’t have a formal registration system for its specimens. One would be implemented in 1848 but by then Hooker was no longer in their employ or even in the country. He was traveling through India and the Himalayas, doubtless collecting more specimens, so was not available to help the BGS properly catalogue his own contributions to their archive. By the time he got back in 1851, the BGS was in the process of moving its collection to new offices.

In 1851, the “unregistered” fossils were moved to the Museum of Practical Geology in Piccadilly before being transferred to the South Kensington’s Geological Museum in 1935 and then to the British Geological Survey’s headquarters near Nottingham 50 years later, the university said.

The discovery was made in April, but it has taken “a long time” to figure out the provenance of the slides and photograph all of them, Falcon-Lang said.

A core of 33 important slides from the collection have been photographed and uploaded to the British Geological Survey’s website. More will follow until the entire collection is online.

If you’d like to know more about Darwin and Hooker’s work and friendship, the Darwin Correspondence Project has almost 1500 letters between Darwin and Hooker available online.
