G. W. Manning at Stakenbridge. "Old Joe" is the students' name for the Joseph Chamberlain Clock Tower at the University of Birmingham, which received its charter in 1900 and is now celebrating its centenary. Birmingham, England's "second city", prospered from metal-working trades, from which enlightened industrialists founded the university.
