What was the world's first supersonic wind tunnel? Who built it and how did it work?

All I've found so far is this Wikipedia article that says:

By the end of the war, Germany had at least three different supersonic wind tunnels, with one capable of Mach 4.4 (heated) airflows.

The citation in the article is a dead link.

    $\begingroup$ The German tunnels were in Aachen (1936, 0.1x0.1 m), Göttingen (1938, 0.11x0.13m) and Peenemünde (1939, 0.4x0.4m, Mach 4.4). $\endgroup$ – Gypaets Dec 10 '16 at 8:11
  • $\begingroup$ @mns Thanks but do you have a source so I can look them up? $\endgroup$ – DrZ214 Dec 10 '16 at 23:17

    $\begingroup$ I knew about the locations from different sources (Bölkow's "Erinnerungen", some googling...). For the years and cross-sections I looked in the same book as aeroalias answer. However, I'm surprised that the tunnel in Göttingen was built so late: reading the phrase before aeroalias citation ("The first suggestion to build a supersonic wind tunnel according to the vacuum-storage principle was made by Ludwig Prandtl in 1917. [...] however, the tunnel could not be realized until the end of World War One. During the same year...") I'd have though that it was built in the early 20s too. $\endgroup$ – Gypaets Dec 12 '16 at 13:13

The world's first supersonic wind tunnel started operating in National Physical Laboratory in Teddington, England in 1922.

It basically used a pressure tank upstream, which was used to generate supersonic flow in a cross section of 20.3 mm, which was used to study projectiles.

From the book Aeronautical Research in Germany: From Lilienthal until Today:

During the same year, the National Physical Laboratory (NPL) in Teddington/England started operating, for the first time ever, a supersonic wind tunnel based on the pressure storage principle ...
