Interesting how this discussion has gone.
There is something appealing about lists by nationality and about misattribution. I agree that what's more important is who made the discovery than their nationality.
What's been missing for me are the sources of the information, otherwise anyone can assert anything, a real weakness on the net(and not just the net).
I haven't given myself the time to consult my books of firsts, of inventions, chronologies, dictionaries of dates.
Just one correction. That "shoulders of giants" quotation. It is in a letter of Newton's. And a 12th century writer said Bernard of Chartres(died c.1130) used to say it. However Burton in his Anatomy of Melancholy quoted Lucan (39-65 A.D.)saying that one Didacus Stella, a Roman general (fl.50 B.C.E.) said "Pigmies placed on the shoulders of giants see more than the giants themselves"(The Latin is given in Burton Stevenson's Book of Quotations), and Didacus is also fingered in Bartlett's 14th.

As Michael Caine might still say,"Not a lot of people know that", apparently including Lord Melvyn Barg.
And as Karl Popper would say,Science doesn't prove anything - what we "know" is just whatever has not yet been disproved.

Happy Hannukah and Happy New Year.
