George Brassai - Graffiti (published 1961)
"Best known for his photographs of nocturnal Paris and its demimonde, Brassai also took pictures of wall carvings and markings over three decades. He was interested in how the images eventually altered, either through additions by later graffiti artists or because of the vagaries of time.”
From a 1964 interview with Brassai:
Brassai, we can say that you’ve been the photographer of Paris’s walls. How did you get so interested in all of these graffiti that made you so famous, in addition to all of these other activities?
Well, I often walked through Paris and I often observed the walls and I thought that everything that takes place on the walls is very interesting.
There are even cracks in the walls, and there are graffiti that people secretly painted there, and I started taking pictures of these things as of 1930-1932.
I had little notepads on which I wrote down the addresses, I could follow their development, because it was a collective work, there were many other people who painted and continued a graffito.
And they say that Picasso followed many of the graffiti artists.
In fact, Picasso himself really likes them, he’s done graffiti, in Montmartre, many of them, and he told me, in a bank, one day he was waiting, he found, he made a graffito, on a wall, and then the manager found out that it was a graffito by Picasso, so he had the wall taken apart, and now it’s in his apartment, along.

Berlin Central Station by Christoph Sevcnikar
The mega Berlin Train Station, Berlin Hauptbahnhof, architect Meinhard von Gerkan and Jürgen Hillmer, the STUDIO HAMBURG Gerkan, Marg & Partners, is capable of receiving more than 1,500 daily trains and 25,000 passengers. Its construction lasted ten years have meant that some conflicts between the German rail company Deutsche Bahn and the architect, in deciding to first shorten the time of execution of the work by modifying the project. It shortened the cover of the station at 100 meters and the lower floors that serve as the underground heat exchanger to be covered, causing no daylight arrived as planned in the initial project.
The construction of the new Berlin Hauptbahnhof is a masterpiece of logistics. While conducting the excavations, groundwater levels were constantly monitored by monitors at once that they were going up the bridges and 1.5 million cubic meters of earth were removed in barges, which otherwise would have required a convoy 1300 trucks miles long.
A complex part of the construction was related to the foundation, as the building rests on a sandy soil on the banks of the river Spree. To overcome this difficulty concrete ponds were constructed at a depth of 25 meters that were filled with groundwater.
Another of the engineering feats that took place in this construction was the laying of a metal bridge that crosses the station across. Because of the risk posed by building it as the station was crowded with people, it was decided to run for a weekend in which the station was closed to the public for 54 hours. Then the structure was built in two parts vertically and 1,200 tons each, and then joined as a drawbridge.
