The reference to "Skyscraper University" is the "Cathedral of Learning" at the University of Pittsburgh.

The Gulf Building (now called Gulf Tower) was the tallest building in the city, at 44 stories. They had an all-around observation deck from which you can see the whole city, the three rivers, and the steep climb of the inclined railway up the cliff on the other side of the river.
