wonderful to see him mentioned here. he also wrote the lyrics to the national anthem of the GDR which are relatively peaceful in comparison with other anthems. Becher is entirely underestimated, but that Borges has mentioned him...and everything that has been edited by Hamburger is worth a look.
Thanks for highlighting this work - I'll look forward to reading more. Wasn't Michael Hamburger a great friend of Sebald? That's commendation enough.
