Logical empiricism dominated Anglo-American academic philosophy by the late 1930s.

Evidence

In the Institute itself, we have been having afternoon or evening discussions, as we did last summer. They are partly to do with economic problems and partly with philosophical ones. In the latter, so-called logical empiricism plays a large part. As is well known, this is currently the favourite philosophical fashion in academic circles … It is impossible to exaggerate the way in which this approach has triumphed across the whole field in scientific circles, particularly in the Anglo-American world. — Rolf Wiggershaus, The Frankfurt School, 748

• QUESTION: Which specific logical empiricists figured in the Institute’s internal debates? The quote ends mid-letter and names no one — worth chasing if the source letter is recoverable.
