This is true in the UK, but in the US his works would fall under the
despicable old US law, based on the years since publication, and also
based on whether the books were printed in the US, whether they were in
English, whether the author was a US citizen, and whether all the
bureaucratic rules were followed and forms filled out. (It used to be
quite possible to lose copyright in the US merely by putting the
copyright notice in some other location than the verso of the title
page; "The Lord of the Rings" lost its US copyright because more than
1000 sets of unbound sheets were imported from the UK to be put into
bindings by the US publisher.

50 years, in all civilized countries. In many, the WWII years didn't
count toward the 50.
