Does anyone know if there exists an English translation of von Neumann's early work in operator theory, in particular the paper *Zur Algebra der Funktionaloperationen und Theorie der normalen Operatoren*?


The full citation is


*von Neumann, J.*, [**Zur Algebra der Funktionaloperationen und Theorie der normalen Operatoren.**](http://dx.doi.org/10.1007/BF01782352), Math. Ann. 102, 370-427 (1929). [ZBL55.0825.02](https://zbmath.org/?q=an:55.0825.02).

If not, are there any expository works in English from around that time period covering von Neumann's work, maybe say pre-1950?



English translation of von Neumann's Algebra der Funktionaloperationen (1930)
If I am not mistaken this has been done by R. Lakshminarayanan
and you can find it in
