Hello Listers,

I am hoping everyone is enjoying the afternoon and would like to post the answer from the POP QUIZ.

Quetion

Please tell me the name of the first meteorite that was etched?

Answer

KRASNOJARSK (1804 by William Thomson)


I would like to congradulate James B being the 10th Lister to send me the correct answer. He will be getting a 120mg Saratov meteorite fragment that fell in 1918 in Russia. And for those of you that would like to read up on the Krasnojarsk meteorite, here is an excerpt from Ernst Florens Friedrich Chladni (1756?1827) and the origins of modern meteorite research By Ursula B. MARVIN


For the next 130 years, from 1808 to 1939, von
Widmanst?tten was credited as the earliest discoverer of the
metallurgical patterns that are named for him in iron
meteorites. The first intimation of a possible rival arose
indirectly in 1939 when Robert T. Gunther (1869?1940), the
Oxford historian and antiquary with a special interest in the
Naples area, examined a mineral collection that contained
numerous fine specimens marked ?Dr. T.? Gunther (1939)
had no clue to the identity of Dr. T. until he came upon a
sample of Vesuvian lava that had been worked into a
commemorative medal honoring the French geologist,
Diodato Dolomieu (1750?1801). The back of the medal was
impressed with the name and date: ?G. Thomson Anglus
1805.? Seeking further information, Gunther contacted
Professor Alfred Lacroix (1863?1948), at the Mus?um
National d?Histoire Naturelle in Paris, who found a letter in
the archives that had been sent in 1801 from Naples in to the
paleontologist, Georges Cuvier (1769?1832), by ?G.
Thomson, gi? Professore di Anatomia ? Oxford.?

***

Gunther?s offhand statement of Thomson?s anticipation
of the Widmanst?tten figures elicited a letter to Nature from
Max Hey (1905?1984) of the Department of Mineralogy of
the British Museum (Natural History). Hey looked up the
1808 issue of the Atti dell?Accademia delle Scienze di Siena
that contained Thomson?s article on the Krasnojarsk
meteorite, which, he noted, was dated ?February 6, 1804.?
Hey remarked that the article is of particular interest to us
because it shows that Thomson studied the action of dilute
nitric acid on the nickel-iron and fully described and pictured
the etch figures, thus anticipating the work of von
Widmanst?tten which, was carried out in 1808 and published
first in 1812 (by K. A. Neumann). Although he documented
Thomson?s priority of publication, Hey made no suggestion
that the etch figures should be renamed for him. Here the
matter rested for two more decades.
