Your uncle was a truly great American, but his obituary is marred by the author's weak grasp of history.

(A 1943 invention would not have been "crucial" to the Battle of Britain - a battle which concluded in 1940)

Here is a link to an article written about him just a few weeks before that expounds on some of the information. You are correct about 1943, I believe he first went with Alvarez in 1940, the 1943 invention I think was implemented later in the war, and a good observation by you, would have been after the Battle of Britian.
