London Under by Peter Ackroyd

London is an ancient city. The Romans established a settlement their a thousand years ago, but they weren’t the first inhabitants of the valley. It sits on soil into which everything slowly sinks. Rivers that brought life to the valley became choked with filth and were buried. The ground under London is thick with history, and the infrastructure of a modern metropolis mingles with the remains of its ancestors. Peter Ackroyd describes what is beneath the surface of that great city in London Under.

Ackroyd goes back to the earliest settlers of the area and the archeological remains of their lives. Their holy places were overbuilt by Roman temples. The temples dedicated to Roman gods were overbuilt by churches. Old paths became Roman roads. The filth of a city covered these roads and turned them back into dirt paths. Modern people paved them anew with brick, and later asphalt or concrete. It’s all still there, though, one thing layered over the other, but often still following the outlines ancient paths.

As you might expect from a man with who has worked with water, some of my favorite chapters relate to the rivers and sewers. London was built around rivers. As the population grew, these rivers became open sewers, carrying away all manner of waste until they were too filthy and stinking to bear. These rivers were enclosed and became underground sewers. As the city grew, it overwhelmed the sewers and turned the Thames into a stinking mess. Eventually it inconvenienced Parliament enough that they engaged the problems seriously in the 19^th Century, putting in place interceptor sewers that carried the waste away from the city. Many of the sewers that are now more than a century old are still in use.

Another feature of London that fascinates my engineering side is the Underground. The city has the oldest underground railway system. The first lines are more than 150 years old. It was built in bits and pieces by competing private companies, though now it is a unified system. The Underground has become such a part of London life that a literature related to it has developed. The tunnels have been the settings of novels and the inspiration for poems.

World War II and the Cold War were another significant phase of buried construction. The British government built many tunnels and bunkers to protect government resources threatened by war. During World War II, so many people sought shelter in the Underground that the government was forced to provide shelter space for people escaping the bombs.

Like any modern city, London now has an extensive underground infrastructure. Pipelines carry drinking water, sewerage, electric and telephone wires, fiber optic cables and all the other things that connect people to services in their homes and workplaces.  These important systems are hidden underground, out of site and possibly too often out of mind, where their work apparently does not disturb the sleeping remains of the many things that had come before.

The Ten-Cent Plague by David Hajdu

Hajdu, David. The Ten-Cent Plague: The Great Comic-Book Scare and How it Changed America. New York: Farrar, Straus and Giroux, 2008.

Earlier this year, the last of the major comics publishers to use the Comics Code Authority dropped it in favor of their own rating standards. The seal of approval was one almost ubiquitous on newsstand comics. It lingered as sale shifted to comic book stores and older readers.

What led to the industry self-censorship represented by the little square seal is an interesting combination of social, political, and economic forces in American history. David Hajdu tells the story. (When The Ten-Cent Plague was published, major comics publishers were still using the seal.)

When comic strips first appeared in newspapers, the intent was to make the papers more appealing to the lower classes and immigrants who might not speak English, or even read. These cartoons appealed to the interest, problems and culture of this audience, along with other minorities, often thumbing their noses at the cultural establishment, the wealthy, political elites and others who had or represented power. As you might expect, the funnies had many detractors among the defenders of decent society.

This same countercultural element was transferred to comic books when they were invented in the 1930s. By the post-war years of the 1950s, the main countercultural was youth. People had been criticizing comics for their possible effects on children almost from the start, but the growing concern about juvenile delinquency (and possibly Communism) led to a successful campaign against comics. Rock and roll hadn’t been invented, so there wasn’t much else to blame.

Actually, a lot of the more reasonable explorations of the connections between comics reading and juvenile delinquency found it to be tenuous if it existed it all (delinquents read comics, but so did nearly every kid who could get an occasional dime). Detractors of comics thought they had evidence enough, especially Frederic Wertham, who’s Seduction of the Innocent added a sense of scientific respectability to the anti-comics camp.


The comics publishers reacted to save their industry from the wave of parental discontent and pending legislation. The Comics Code was a self-censorship standard like the film industries Hays Code, except much more restrictive. The code, and the forces that led up to it, almost killed the comics industry. It mostly eliminated the crime and horror comics that inspired the most ire through their excesses.

While Hajdu agrees that the crime and horror comics of the 1940s and early 1950s often had material that was unsuitable for children, he finds the roots of the anti-comics movement to be in the fundamental shift in culture between generations that occurred during the cold war. He also exhibits a lot of sympathy for the writers and artists that created comics, some of whom who left the arts altogether after the industry contracted.

Hajdu’s style is journalistic, like other works of popular history. The bibliography is extensive for those who are looking to make a study of comics. There is a touch of humor, which is bound to come up given the sometime goofy nature of comics and the ironies that abounded in the arguments both for and against the medium.

Lights Out by Ted Koppel

Much of the world, and America is particular, is heavily networked through a vast, distributed communication system of computers, cables, and transceivers. All this runs on electricity. Our major infrastructure is dependent on electrical power: water, sanitation, healthcare, communication and transportation. These systems, indeed even the systems that generate and distribute electricity are increasing controlled by networked computers.

This makes America extremely vulnerable to cyberattacks aimed at the electric system. If a major section of the power grid goes out, millions of people could be left without clean water, waste disposal and food. A well-orchestrated cyberattack could leave large parts of the country without power for as long as a year.

Journalist Ted Koppel explores this situation, and criticizes America’s state of unpreparedness and sometimes denial, in his book Lights Out. There are three major parts to his book.

First, he explores the vulnerability of the electrical system to cyberattack. I think he makes a fairly convincing case that the system is vulnerable and that some agents very likely already have the capacity to cause major damage to the system that could affect huge parts of the country.

Second, he looks into the state of our policies and preparedness. As you might expect for a nation of 50 co-sovereign governments, it is a patchwork. In addition, the major actors in preventing, planning for, and responding to catastrophes are focused on natural disasters or physical attacks by terrorists. These things shouldn’t be ignored, but the scale of a cyberattack on the electrical system could have a much larger scope in terms of the populations and territories affected.

Finally, he looks at how prepared the country is for the aftermath of such an attack. The answer is we are woefully unprepared. He looks into the prepper movement and the vast resources the Church of Jesus Christ of Latter Day Saints has put into readiness. He finds some models there, but no one has the resources to respond to such a massive disaster.

Of course, the issue is not simple. Preventing such an attack is difficult even if all the competing interests (utilities, federal agencies, local and state governments, privacy advocates, and many others) could agree on what to do, who should do it, and how far their authority should extend. It is all hugely expensive, especially preparing to respond to a massive outage, and it would take years to get ready.

Even so, Koppel clearly thinks we should acknowledge this vulnerability and start doing something about it. An imperfect plan, even if it is too little to late (it’s already too late because cyberattacks are already happening and major attacks could be launched with the press of a button), is better than no plan. He looks to the civil defense planning during World War II and the Cold War. Much of it was misguided or for show, but we learned valuable lessons that helped us make more effective responses and develop better policies.

Koppel writes as a journalist for a wide audience, and that was his intention. Readers do not need a background in engineering, utilities or security to understand the issues he brings up or their implications.
