It's good to work on another of your questions.
Martin Fleischmann was born in 1927 and is almost certainly living in
semi-retirement in England.
There's a limit to what I can say here, without disrespect for his
privacy (and Google Answers rules) but I can refer you to a conference
where he gave a paper last year. I'd also point out that there has
been no news of his death in likely places, such as the London Times.
"Martin Fleischmann, now a naturalized British subject, was born March
29, 1927, in Karlsbad, Czechoslovakia . ."
Although many articles spell his name Fleishman, Fleischmann is the
spelling given in the Royal Society membership list:
This webpage shows that Fleischmann contributed a paper to the 10th
International Conference on Cold Fusion, held in August 2003:
You may be able to find out if Fleischmann will participate in the
2004 Conference by keeping an eye on this website:
(Here's a picture of Fleischmann at the 2002 conference.)
The Times and Sunday Times (London)
Most recent reference 2002:
I found nothing about his life since the August 2003 conference in the
Lexis-Nexis UK newspaper database.
Hoping you are happy with this information - but please ask for
clarification if I can be of any further help -
