EducationSwedish mineral name challenge

15th Dec 2011 21:04 UTCVan King Manager

For many years I have been trying to find out for whom tengerite was named. Dana named the mineral in 1868 for "C. Tenger" because Tenger was listed as a co-author with Svanberg on a paper about the, then, unnamed mineral. The only time I have found a "C. Tenger" who even had a somewhat technical background was a person who was an "agronomen" - agronomist. I have believed that Tenger was a student at Uppsala and probably graduated as a Ph. D. about 1836-1840. Anyone able to go to the university to see old books listing graduates or perhaps similar books scanned and available online?

Van,

I will dig a bit. Doesn't seem as if he has written any thesis or anything printed for that matter. Cannot find him in Libris http://libris.kb.se/form_extended.jsp?f=ext

I see there are some letters at the academy of science to Berzelius and Lindström

http://centrumdb.kva.se/brev/ipac/FrameSet.jsp

But no details about the man in the register more than "Chr. Tenger" which suggests that his name is Christian.


I will probably find out more at the University library.


cheers

Hi Van


In the following publication:


A DICTIONARY OF THE NAMES OF MINERALS INCLUDING THEIR HISTORY AND ETYMOLOGY (1896)

by ALBERT HUNTINGTON CHESTER E.M. Ph.D. Sc.D. Professor of Mineralogy in Rutgers College


It's simply recorded as follows:



TENGERITE. /. D. Dana, 1868, Dana Min., 710, after C. Tenger, who examined it.

Carbonate of yttrium, found as a thin, white coaling on gadolinite.


Not much, but something

Cheers

Dear Johann,


With the possible "Christian Tenge", I found one in geneealogical websites born 1800 (perhaps an OK birthdate for a student) and he was born at Westervik, Kalmar and Vestervik, Ostergotland depending on the website. Consistent. The same person appears in Sveriges Staatkalendar for ar 1883 utgifven efter Kogl. Maj:TS nadigste forordnande af dess Vetenskaps-Akademi published in 1882 and his full name is given as Johan Christian Tenger and he was born in 1800 in Vestervik. He was seemingly listed at a consulate. This would be normal as most people in the time period probably had careers outside of their training. As a political figure, it would be easier to locate a biographical sketch or obituary. This could be someone else also. The connection with mineralogy and Svanberg would be necessary.


Best Wishes, Van

Later in this book, there is a Carl Fredrik Tenger. f. d. Lojtnant 82.


Is this a book about people receiving pensions?

16th Dec 2011 16:59 UTCJohan Kjellman Expert

Hi Van,

I don't know what this book is about. Those guys are too young.

However, the biggest dig ever for Tenger has started - the word is out at two royal academies - and things are looking really good. More later.


cheers

Van here we go…

First a link to the "type description", or better original report, which is actually just a short note by Berzelius in his Årsberättelse om framstegen i fysik, kemi och mineralogi :

http://books.google.se/books?id=3wtPAAAAYAAJ&pg=PA206&dq=tenger+svanberg&hl=sv&sa=X&ei=lmP4TvP5FaL64QSJ3sCNCA&redir_esc=y#v=onepage&q=tenger%20svanberg&f=false


in translation something like this:

"A. F. Svanberg and C. Tenger have to the Science Academy Museum announced that they have found a new mineral from the Ytterby feldspar quarry. It is carbonated earth of yttria. It occurs mostly as thin white crusts, which in recent years has been found in the cracks of gadolinite, but it has also occurred in another association, in so thick masses, that one has been able to investigate it. Sometimes one sees signs of a radial crystallization." So far the "type description" or better original report.

It seems likely that both the mineralogical museum in Uppsala and the one in Stockholm should have something that we could designate as "original material".


Tenger then was hard to find anything on to begin with.

Eventually, I found two independent genealogies of the Tenger family and it seems they all stem from Västervik where the men mainly have been merchants and/or merchant skippers or marine officers.

I found 12 men with the initial letter C in one of their names, 10 were named Christian.

But only three candidates had the "right" age, they are closely related as the fathers of 1 and 2 and the grandfather of 3 are all brothers:

1. Christian Tenger 1794 - 1859, Merchant in Västervik

2. Anders Christian Tenger 1800 - 1842, Lieutenant, living in Ödeshög parish

3. Magnus Christian Tenger 1806 - 1862, Lieutenant, ”help-teacher” in chemistry, later director of the agricultural college in Orup, Skåne


No 1 only fits in age - no other correlation.

It turned out that nr 2 is the one who wrote to Berzelius the letters are now in the academy archives and there is nothing in them that suggests that he has anything to do with minerals.

I found a short biographical note on no 3, and it turned out that he was "repetitör i Chemie" at the artillery grammar School Marieberg near Stockholm from 1835-1837. Moreover I found out that Adolf Ferdinand Svanberg became teacher in mechanics and mathematics at the same place in 1835.

That is all I have but it seems to be a pretty strong case for no 3.

I will let you know if I find anything more.




Happy New Year everybody!
