The Fan House for the Liberty Tubes

Update: Although it is often written that the fan houses were built in response to the near-disaster of the Tubes’ first traffic jam, it turns out that the ventilation system was planned from the beginning, with the fan house and stacks at their current location. Source: The American Contractor, July 14, 1923: “Fan Houses & Stacks: $133,000. 1 sty. 190×110. Liberty Tunnell, cor. Senate [sic, = Secane] & Ruth, Pittsburgh. Archt. A. D. Meeld, 708 Bakewell bldg., Pittsburgh. Owner The Commrs. of Allegheny Co., A. C. Gumbert, Court House, Pittsburgh. Brk. & limestone. Gen. contr. let to Williams & Hass, Empire bldg., Pittsburgh. Htg. & plmg. to United Gas Improvement Co., Broad & Arch sts., Philadelphia, Pa.”

Father Pitt keeps the original article below, but read it with that knowledge in mind.

When the Liberty Tubes opened in 1924, they had no ventilation system. They didn’t need one, the engineers said. Cars whooshing through the tunnels would carry the bad air out with them.

If you have ever driven in the Liberty Tunnels at rush hour, you can probably spot the flaw in that theory.

It did not take long for the flaw to become obvious. On May 10, 1924—when a transit strike was going on—a traffic jam filled the tunnel, and more than forty people passed out and needed medical attention. It was lucky no one died.

The fan house finally went into service in 1928. It has four giant chimneys, two for intake and two for exhaust. They’re a prominent landmark on the back side of Mount Washington, although it can be fiendishly difficult to find one’s way to them in the warren of precipitous streets.

We should note that sources disagree about whether the fan house was part of the original plan. In some tellings (like the Wikipedia article), it was a reaction to the disastrous traffic jam of May 10. In others (like this very interesting feature from WESA), it had been planned all along, but the tunnels were opened well before the ventilation system was completed. Father Pitt has not been able to sort out which version is the real story in the limited time he was willing to devote to research, and he invites anyone with a good source to speak up in the comments. (Update: Father Pitt himself found the good source, and you have seen the results in the update above.)

Church of the Holy Cross, Homewood

In many neighborhoods this would be the most distinguished building, but of course Homewood has Holy Rosary Church. Nevertheless, this is an important building in its own right. It was built in 1904 as St. James Episcopal Church, but in 1953 it was bought by a Black Episcopalian congregation, which obviously showers love on this building. It was designed by Carpenter & Crocker, and the grandson of William James Carpenter gives us the story of the church on a site dedicated to his grandfather’s work. You can also read the story of the congregation from the church’s own site (the link goes to a page where you can download a PDF file).

Duquesne Brewery, South Side

This started out as a fine Romanesque design for an industrial building; it sprouted more and more haphazard additions, and became something more like a European castle with its layers of contradictory history. Today, after an adventurous history of abandonment and adaptation, it is called “The Brew House” and is filled with lofts and artists’ studios.

A Black Stone Survivor: First Methodist, Knoxville

Few of these black stone buildings are left, but in some of the less prosperous neighborhoods we can still find uncleaned stones. Knoxville is a particularly interesting neighborhood from the point of view of the urban archaeologist: it was prosperous and now is not, so it retains some splendid buildings in their original state, many of them sadly abandoned and decaying. This church, marked “1st Meth. Prot. Ch.” on a 1916 map, is still in use as a nondenominational church, and old Pa Pitt very selfishly hopes that the congregation always sits at that middle point where it has enough money to keep the doors open and not enough to clean the black stones.

Addendum: The architect was Knoxville’s own Edwin V. Denick. “Fine New Church for Knoxville,” Pittsburg Press, November 1, 1908: “In the newly opened section of Knoxville, between Charles street and Rochelle street, the Knoxville Methodist Protestant Church congregation of the South Side is erecting a handsome stone building. The structure is under the direction of Edwin V. Denick, architect, and will occupy a plot 100×100 feet at the northeast corner of Zara street and Georgia avenue. The main auditorium will have a seating capacity of about 800. The subfloor is divided between gymnasium and The style is modernized Gothic in the exterior plan and design. The work is well in progress and it is intended to complete the structure about August 1, 1909.”

Old Engineering Hall, Oakland

Old Engineering Hall at the University of Pittsburgh is a fairly successful marriage of modernism and classicism. It is almost postmodern avant la lettre, with classically inspired details but a shape that owes nothing to the classical world. It was built in 1955, when it was still common for modernist buildings to apologize for themselves by including a few dentils and a suggestion of a Greek-key frieze. This was Engineering Hall for only about fifteen years; the School of Engineering moved out in 1971 (into the uncompromisingly modern Benedum Hall), and since then this building has been put to such miscellaneous uses that the university has never been able to come up with a better name for it than “that building that used to be Engineering Hall.”

Carnegie Library, Lawrenceville Branch

This fine little Renaissance palace, built in 1896, was the first of Carnegie’s branch libraries, and thus arguably the vanguard of the whole idea of branch libraries. It was also the first public library with open stacks, where patrons would just walk to the shelf and pick up the book by themselves. In other libraries—including much of the main Carnegie in Oakland until a few years ago—the patron would ask for the book at the desk, and a librarian would run back to the mysterious stacks and fetch it.

Like all the original libraries in the Carnegie system, this was designed by Alden & Harlow.

Saint Joseph’s Hospital, South Side

Built in 1907 (or 1911, depending on our source), this central section has not changed much except for the new windows too small for the openings. The architect was John T. Comès, famous for Romanesque churches like St. Augustine’s in Lawrenceville and St. Leo’s in Marshall-Shadeland. Here he gave the Sisters of St. Joseph a kind of Mediterranean Romanesque tower with a billboard on top. It was later encrusted with featureless modern buildings all around it, and the whole complex is now retirement apartments under the name “Carson Towers.”

This PDF has a picture of the original building. The caption that says “The sculpture over the front door is the only part of the original facade still visible on the building that is now Carson Towers” is obviously wrong; as even a quick glance will show us, almost nothing except the windows and the cornice (cornices often go missing, and somewhere there must be a huge cornice graveyard) has changed about this façade.

Under the Asphalt

Scratch any major street and you’ll find streetcar tracks, as we see here on Carson Street on the South Side, currently under construction.

The Knoxville Junior High School

This splendid Tudor Deco palace takes up a whole large city block; in fact, it’s the symbolic center of Knoxville, occupying the lot where the original W. W. Knox house stood until the early twentieth century. The school was built in stages, beginning in 1927; the Charles Street front was finished in 1935. The architects were Press C. Dowler and Marion M. Steen, and the building was placed on the National Register of Historic Places for its architectural significance, as part of a package deal with a number of Pittsburgh public schools.

The school closed in 2006. It may stand for many more years, since Knoxville is not a prosperous enough neighborhood to make it worth demolishing; but it will eventually become too dangerous to let stand, so it is in danger until another use is found for it.

The main entrance is designed to impress us with the idea that education is important but also delightful.

These shields above the entrance express an ideal of balance in public education: Art, Science, Trades, Play.

Even the side entrances are finely decorated.

Litchfield Towers, Oakland

These skyscraper dormitories were built in 1963 to designs by Dahlen Richey of Deeter & Richey. They were poetically named A, B, and C, but students immediately renamed them Ajax, Bab-O, and Comet.

The restored entrance looks like a scene from the modernist paradise that existed mostly in architects’ imaginations. But the original architect certainly did not specify the weirdly incongruous faux-antique lanterns.
