When did Sir Karl Popper become a naturalised British citizen?

dwm78 --

According to an authoritative biography, Karl Popper became a British
citizen in 1949.  The source for this information is "Karl Popper -
The Formative Years, 1902-1945 : Politics and Philosophy in Interwar
Vienna,"
by Malachi Haim Hacohen, Cambridge University Press (2002), at page 500.

You can access this information yourself online and read it in in
context by using Amazon.com's useful feature called "Search Inside
This Book."  To do that, first go to the Amazon.com listing for the
book, which you can find at this link:

Amazon.com: Karl Popper the Formative Years
http://www.amazon.com/exec/obidos/tg/detail/-/0521890551/qid=1091026152/sr=1-10/ref=sr_1_10/104-0356549-7527950?v=glance&s=books
  
Then click on the image of the book on that page, which will provide a
"search box" captioned "Search Inside This Book."

In that search box, enter "citizen in 1949" (in quotes), and in the
short list of search results, you will find a brief excerpt labeled
with the hyperlink "on Page 500."  That excerpt includes the complete
reference to Popper's grant of British citizenship:
"(Britain would naturalize him on November 1, 1946, and he would
become a citizen in 1949.  Austria would restore his citizenship a few
decades later.)"

If you want to read the context surrounding the quote, click on the
words "on Page 500" and you will see an image of that entire page.  At
the bottom of the page, you will see hyperlinks that allow to move to
the previous pages (498 and 499) or to the following pages (501 and
502) as well.


Additional Information:

I was struck by the fact that Popper apparently was naturalized three
years before he was granted citizenship, since I would have assumed
that those events would occur nearly simultaneously.  I don't have a
definitive explanation of that, but I did come across a website that
indicated that until the British Nationality Act of 1948, "[t]he law
on nationality was spread across many statutes, and much of it was
unwritten":

I am confident that this is the information you are seeking.  If
anything is unclear, please ask for clarification before rating this
answer.

Thank you - my first experience of Google Answers!  This fact is
(surprsisingly) not included in any of the obvious Popper
websites.Very impressed by the speed of your response and presence of
a cited reference.  dwm78

This proved to be tougher to nail down than I thought.  Malachi Haim
Hacohen's book, "Karl Popper -- The Formative Years," apparently
discusses his naturalization as an English citizen on page 500 but I
don't have access to the book:
Amazon.com
http://www.amazon.com/exec/obidos/tg/detail/-/0521890551/qid=1091026152/sr=1-10/ref=sr_1_10/104-0805329-1735916?v=glance&s=books

I've checked several biographies of him and even his Sept. 18, 1994
obituary in the New York Times but not had any luck pinning down the
year or date that he became an English citizen.  Perhaps someone with
access to Hacohen's book can answer this precisely.

As you're probably aware, he came to London from New Zealand to
lecture at the London School of Economics in 1945.  In 1949 he was
made professor of logic and scientific method.  He was knighted by
Queen Elizabeth II in 1965.
