Mies' Barcelona Pavilion Walk-Around


There are gobs, oodles -- whatever term for large numbers -- of photos of Mies van der Rohe's iconic "International Style" German Pavilion built for a 1929 exhibition in Barcelona, destroyed after the event, and rebuilt in the mid-1980s. The Wikipedia entry on the Barcelona Pavilion (its common name) is here and another reference is here.

Unlike most modernist architecture, the Barcelona Pavilion oozed sex appeal and thereby served as inspiration for architects who had to hide in the bomb-shelters of Theory during the hard times of the Great Depression, the distraction of World War 2 and the five or ten years of post-war sorting-out that all took place before "significant" modernist buildings began appearing in number.

I confess that when in high school and college, I loved gazing at black and white photos of the original pavilion and lamenting its loss. And despite the aesthetic ruin manifested by across-the-board modernist architecture we have to live with today, I retain a soft spot in my heart for the pavilion -- van der Rohe's only real masterpiece (in my opinion, of course).

So when I recently found myself in Barcelona for the first time, the pavilion was on my must-see list along with certain works by Antoni Gaudí that I'll deal with later.

I mentioned above that many sets of photos exist of the rebuilt pavilion; they are all over the Web. Many are of nice, professional quality. Nevertheless, I thought I'd use this post to toss in my two bits worth of photos taken during a brief visit I paid while on my way to the big museum featuring Catalonian art. Here goes:

This is the Barcelona Pavilion in its present setting (it's that low, white structure in the background). From what I read, it's sited where the original was in 1929; presumably the large, open area was filled with other pavilions then.

Here's the entrance approach for those coming from the direction of the Plaça d'Espanya. You climb those steps and deal with the fellow on the platform to pay admission.

Admission paid, I entered and was facing towards the right side of the structure.

As in 1929 this area (can I call it a "room"?) has some Barcelona Chairs and hassocks. In the background is the same statue (so far as I know) by Georg Kolbe that was in the original pavilion.

Moving past the Barcelona Chairs to the pool area and statue. I included some of the structure at the left of the photo so that you can see how it is arranged.

I've walked a few steps and am now at the back side of the interior; here's how the statue's setting looks from this position.

Doing an about-face, I see this view along the back of the structure. That small enclosure in the background might have been office space in 1929: today, it's a bookshop.

These three photos are a kind of panorama of the back side of the pavilion, something not always pictured. It's quite possible that the place I was standing was occupied by other buildings making this vista unimportant in 1929, but I cannot confirm this.

Moving towards the front, here's a view of the large pool with its stony bottom. In the shady background is that shop.

Returning almost to the entrance, I see this. The seated man is the ticket seller.

Finally, a parting shot of the Barcelona Pavilion.

What's Not Where


I'm back from Spain, Portugal and Morocco. And still wiping the jet lag cobwebs from my brain -- but post, I must.

For starters, here are two slogans I came across:

This was taken at Casa Pepe, a road house just off the Autovia between Granada and Madrid. Pepe seems to be a huge fan of General Franco, the late Caudillo of Spain (I'll have more on Pepe's place in another post.) The slogan on the sign to the right can be translated as "This is Spain, not Europe."

I noticed this in Barcelona between the Plaça d'Espanya and the Museu Nacional d'Art de Catalunya. It's in English, presumably to get the message across to a wide foreign audience. Catalunya (better known to English speakers as Catalonia) is a region in northeastern Spain that has its own dialect which is slightly similar to dialects in southern France. Not all Catalonians consider themselves Spanish, it seems.

Do Political Paintings Age Well?


Painting overtly political subjects can be a risky task. There's the obvious risk of supporting a side that eventually loses -- will the winners seek retribution? But another risk is that, once an issue is no longer current, the paintings will be forgotten and the artist as well. Which might be why political paintings represent a rare genre.

Another consideration related to transitory political issues is painting technology. While a painting might take weeks or even months to complete, posters can be on the streets in a matter of days from when an inspiration strikes. This is why most political art is in poster form.

Before the 19th century most art was commissioned by the church, state, and rich or powerful individuals. Political content, such as it was, therefore was mostly in support of those who hired the artist. That is, anti-establishment painting subjects were rare because they were seldom funded. As painters became less reliant on traditional commission sources, they became increasingly able to create critical art.

Liberty Leading the People - Eugène Delacroix - 1830
As is noted here, Delacroix's famous work commemorates a successful regime change even though it appears to be a call to arms. The new regime (that of Louis-Philippe) eventually entered history's dustbin, but the huge painting lives on in the Louvre.

The Arsenal - Diego Rivera - 1928
The Russian revolution is glorified and a Mexican version encouraged in this mural that even includes Rivera's occasional wife Frida Kahlo as the central subject. Mexican governments at the time regarded themselves as "revolutionary" and tolerated such themes for murals on public buildings.

Eternal City - Peter Blume (1906-92) - completed 1937
I wonder how many people today would be able the grasp the context of this painting if they encountered it at New York's Museum of Modern Art and saw a plaque containing only the information above. The subject is anti-Fascism and the green jack-in-the-box figure represents Italian dictator Benito Mussolini. No one under age 70 can remember the living Mussolini who is increasing an historical footnote.

By Zina Saunders
This looks like a computer-generated "painting" (note the treatment of the plane's engine cowling) though in principle it could have been rendered in oil, acrylic or gouache. Like Blume's painting, it is likely to age poorly because it isn't very interesting artistically and deals with an ephemeral subject requiring specialized knowledge (i.e., Sarah Palin likes to hunt).

"Truther" poster by William Groshelle
Here is the sort of political-themed "art poster" common since the mid-1960s and reaching a climax during the presidency of George W. Bush (shown). Many current political-themed posters make use of computer-manipulated collages such as seen here; it's a quick way to create something with visual interest and realistic looking detail. Were this a painting, I doubt it or its artist would be long-remembered. It's too topical and historically questionable.

French Battleships: Steampunk to Sleek


The French are known for elegant design as well as a self-proclaimed devotion to la logique. For some reason, French battleships (cuirassés) designed before the Great War had looks that ranged from awkward to ugly. Perhaps logique triumphed over elegance. When battleship programs renewed in the 1930s all this changed and the new French battleships were among the most attractive in the world.

In fairness, nearly all the world's battleships designed before 1905 were awkward-looking. In part this was because they tended to sport several sets of different-sized guns. Starting with Dreadnought (launched 1906), battleships had a set of main guns and another of smaller guns for fighting off torpedo boats. In World War 2, secondary armament was devoted to anti-aircraft guns what cluttered much of the ships' superstructures. Nevertheless, appearance usually remained much less awkward than for pre-Dreadnought ships.

Below are two examples of French battleship architecture, one from each design era.


Voltaire - (Danton class) - 1911-1937
Voltaire was part of the 1906 battleship program whose initiation happened to coincide with the launching of Britain's Dreadnought, the first modern battleship. (The French Wikipedia entry on the Danton class is here.) French naval shipbuilding was a slow process, perhaps because the army was considered more vital. In any case Voltaire, which entered service in 1911, was what now is termed a "pre-Dreadnought" design that was instantly made obsolete at Dreadnought's 1906 launching.


Richelieu - 1940-1967
Richelieu (Wikipedia entry here) was still fitting out at Brest when France was about to surrender. However, it escaped and served with the Allies during World War 2. Its main armament is of interest because the eight guns are mounted in two forward turrets. Typical main armament at the time was nine guns, three to the turret, with two turrets mounted forward and one to the rear.

Airport Gate as Holding Tank


A byproduct of a recent round-trip between London and Paris was the experience of using British Airways' new Terminal 5 at London's Heathrow airport.

To most Americans, the mechanics of flight departure at Terminal 5 would be basically normal, given the usual expected minor variations between airports. But this actually is just one of two major passenger processing alternatives found around the world. Consider Heathrow's Terminal 3, where non-British Airways flights to North America originate.

At Terminal 3 onc encounters the usual drill. First is passenger check-in coupled with a few security-related questions and details. Then one moves on through the usual security inspection process. Once "sanitized," the next destination is a mini-mall full of duty-free and other shops where you can trade your excess pounds for anything from a Cadbury candy bar to a Gucci purse. So far, pretty standard stuff.

The big difference comes when one leaves the shopping zone for the departure gate. In America, a departure gate usually amounts to a section along one side of a long, glassed-in hall where can be found a door to the aircraft ramp, a check-in desk and lots of seats for waiting passengers. But in Heathrow 3, that long hallway is flanked by what amount to holding tanks -- rooms containing the usual ramp door, desk and seating.

At least you are free to leave the tank, something you can't do elsewhere. In some cases, passengers go through a final passport inspection before entering the tank: after, they're stuck. Seems to me this was how it worked in Copenhagen.

Perhaps some people find all this lots of jolly fun. I think it's the usual processed-meat airport experience raised to the next higher power. Moreover, I don't find it necessary; the normal U.S. style procedures work just fine and eliminate some of the totalitarian overtones.

For what it's worth, here are some airports where I had that warm, fuzzy holding tank experience: Vancouver and Toronto (in the 1980s -- things might have changed since), Copenhagen and Heathrow 3. Mercifully, I can't recall how things worked at places such as DeGaulle 1, Orly-Sud, Helsinki and Frankfurt.

Tri-Motor Aircraft, 1930-1950


Most aircraft either have a single motor or a number of motors evenly divisible by 2 (2, 4, 6 etc.). Odd-number engine counts such as five and seven are possible, but only tri-motor aircraft saw significant production in the odd-count, multi-engine category.

There are two main reasons for going the three-motor design route. One has to do with safety. In the days when reciprocating engines were the norm, reliability of such motors was often questionable. In the early days of aviation, motors were comparatively crude and their design imperfectly understood. By the 1940s, engine design was pretty well understood, but reliability was compromised by the quest for ever more power. In the case of radial, air-cooled motors, the route to more power was through adding cylinders and accessories such as turbocharging. The result was complexity that led to unreliability that plagued aircraft such as the B-29 bomber and Super Constellation airliner.

So, if four engines couldn't be justified, then why not have three if the loss of one motor on a two-motor plane was too risky.

Actually, this implies that only one working motor might not have the power to maintain flight. And this is the second reason for tri-motor craft: in many cases (especially in the years around 1930) two motors weren't really sufficient to power large (at the time) transports and bombers.

Tri-motor aircraft have some disadvantages. The odd engine count precludes having engines driving propellers turning in opposite directions in order to cancel out torque effects imparted by propeller rotation. A motor mounted at the nose of an aircraft usually impaired visibility for the pilot. Post-World War 2, the center engine would also occupy space that would ordinarily be used by a radar set.

The initial heyday of tri-motors was the early 1930s. Three-engined jet airliners were common for a number of decades starting in the early 1960s. But that's a subject for another time.

Below is a gallery of tri-motor aircraft in the years before 1950.


Ford Trimotor and three-engined Boeing 727
This photo was taken in 1964 or 1965 showing both planes in American Airlines livery. I saw this restored Ford at the 1965 New York World's Fair.

Fokker F.VIIb
This was a rival to the Ford. Pictured here is the one flown by Sir Charles Kingsford-Smith on some of his long-distance flights. It also was the type of plane that crashed, killing famed Notre Dame football coach Knute Rockne. A factor in the crash was Fokker's use of wooden construction for the wings, spelling commercial doom for the F.VII: Fords were all-metal.

Stinson SM6000
Yet another high-wing monoplane tri-motor.

Stinson Model A
This was a low-wing tri-motor representing a trend away from high-mounted wings for monoplane transports. Several airlines used it during the mid-1930s, as indicated here.

Pander S-4
Pander S-4 at Mildenhall, England
Pander was small Dutch aircraft company (Wikipedia entry here) that built the S-4 as a prototype fast mail plane. It was perhaps the sleekest piston-engined tri-motor ever built, but unreliable. It was destroyed in a crash in the 1933 London-Melbourne competition.

Junkers Ju 52
The Ju 52 (alias Tante Ju) was by far the most successful piston-engined tri-motor, nearly 5,000 being between 1931 and 1952.

Savoia-Marchetti SM79 Sparviero
Both bomber and transport versions were built of this general design. Three motors were used for the bomber because Italy lagged behind Germany, Britain and, to a lesser degree, France in engine horsepower.

Northrop YC-125C
Three-engined planes were considered passé after World War 2, yet for some reason Northrop produced the archaic-seeming YC-125 in test-batch numbers.

Martin Martin XB-51
This flashy prototype jet attack bomber classifies as pre-1950 because its first flight took place 28 October, 1949. The "T-tail" and positioning of the forward engines are tell-tales of the influence of World War 2 German design as well as active participation by Hans Multhopp who helped design the Focke-Wulf Ta 183 fighter that was never built, but influenced the later Saab J-29 (Sweden) and MiG-15 (USSR).

Racing Hydroplane Design Evolution


This probably isn't a big spectator sport in your neighborhood, but it was huge when I was growing up in Seattle. I'm talking about unlimited-class hydroplane racing.

This expensive sport was centered in Detroit for much of the first half of the 20th century and then caught fire in Seattle, as I'll explain below. Races are held elsewhere and there are pockets of interest in Madison, Indiana and a few other places, but Seattle and Detroit remain the heart of unlimited racing.

Being interested in design evolution, I've kept a casual eye out for changes to the physical form of unlimited hydros for years. The photos below summarize what's been happening these past 80 years.


Miss America X
Gar Wood's Miss America racers dominated the sport into the early 1930s. The Miss America shown above had a shallow V-bottom and "steps" such as are found on the bottoms of flying boats and float-plane floats. The concept was to lift the boat as high above water as possible so that it would tend to skip across the surface rather than plow through it. This goal is constant in power boat racing; what varies is the means used to maximize the effect.

Miss America X's four (!) engines
Miss America X was unusual in that it had four motors. Most unlimiteds make do with one and occasionally have two.

Tempo VI, owned by bandleader Guy Lombardo
Tempo VI, a pre-World War 2 design incorporates sponsons mounted on each side of the front part of the hull. These further raised the boat above the water; the "wetted area" comprised the rear underside of each sponson and the underside of the hull near the stern.

Miss Pepsi
Somewhat retrograde circa-1950 was Miss Pepsi which had a step-type hull similar to that of Miss America. Regardless, the Pepsi was very competitive against even the advanced designs exemplified by Slo-Mo-Shun IV (below).

Slo-Mo-Shun IV
Slo-Mo was designed by Ted Jones and owned by Seattle Chrysler dealer Stanley Sayres. It set a world straightaway speed record for boats in 1950, hitting 160 miles per hour on Lake Washington. Later that summer it traveled to Detroit and easily won the Gold Cup race which then was held in Seattle for the next few years.

Slo-Mo-Shun IV at speed
This shows Slo-Mo as she might have looked when setting the speed record. Note the characteristic high "rooster tail" of spray. This was a side-effect of Jones' design innovation. The wetted areas were small patches of the rear undersides of the sponsons. The rear part of the hull did not scrape the water as did Tempo VI. Instead, the final touch point of the so-called "three-pointer" was the propeller itself. It's the half-submerged prop that kicks up the rooster tail. For the last 60 years nearly all unlimited hydros followed this design approach.

Miss Budweiser, circa 1980
Front view of circa-1980 Miss Budweiser
As with Formula 1 racing cars, hydro designers decided that it was advantageous to improve driver visibility and improve comfort (sitting behind the engine exposed him to heat and fumes). Hence the "cab forward" design illustrated here.

Turbine-powered Miss Budweisers
For many years after World War 2 unlimited hydroplanes were powered by water cooled fighter plane engines-- Allisons at first, later by Rolls-Royce/Packard motors. But these were temperamental when modified to power racing boats and supplies of them were drying up. By the 1990s most designers switched to gas turbine power; note the air intakes shown in the photo. (The turbine drives a propeller, just as piston engines did.)

Another concern was driver safety. Unlimited hydro racing accidents cost the lives of a number of drivers over the years and resulted in serious, career-ending injuries to others. A solution that has worked well is the adaptation of cockpits from F-16 fighters for hydro use. Rather than being thrown out of the boat, the driver rides out the accident strapped to his seat in a waterproof enclosure with its emergency oxygen supply. These cockpits can be seen in the photo.

Flipped hydroplane -- shows plan view of recent designs
Slo-Mo-Shun IV had a spade-like profile when seen from above. This design proved to be too prone to the bow end lifting the boat into a spectacular back-flip. Some of this might have been due to aerodynamic lift if the boat's angle of attack changed, but the main reason had to do with air pushing on the underside of the hull, a force that becomes ever-stronger as the angle deviated from the horizontal. Over time the spade shape was abandoned for a "pickle fork" treatment that, suitably evolved by wind tunnel testing, resulted in the plan view seen here. Note the holes toward the front that lessen a potential flip-producing force. Obviously, flips still happen. But they now are more likely to result from digging into water stirred up by racing activity than being lifted higher after a bounce.

Many subtle improvements have been made, so today's hydros can lap a 3-mile racetrack-shaped course at speeds of 150 miles per hour -- not much less than Slo-Mo's 1950 straightaway record run. (Records after a 178 mph run in 1952 by Slo-Mo-Shun IV were set by prop-less jet-propelled boats. The current mark is just under 318 mph, set in 1978 -- Wikipedia entry here.)
