Scientific American Archives 1845-1909 available until November 30, 2011

Scientific American has just opened its archives for the years 1845 to 1909 until the end of November.  Details can be found at

The archives is very useful for the meteorite historian - articles and letters relating to meteorites, meteors, aerolites, etc., can be downloaded for free until November 30.

To use the resource efficiently, click on the link "Advanced Search" in the upper right-hand corner of the web page, which will bring you to the following search page: American.

Enter your search word at the top, for example the word "meteorites", and then scroll down to the bottom of the page, and select sort by "Date - Oldest".  I pulled up 810 hits for this search, and if the articles are between 1845 and 1909, you can just click on the title and download the article for free.

The first item on my retrieval list was entitled "Meteorites - Their Origins", which was published on page 94 of the December 9, 1848 issue of Scientific American and discusses Charles Upham Shepard's views on meteoritic origins.

I haven't done much searching on the archives yet, but I am sure it will turn up some really nice items for those interested in the history of meteorites.  Happy searching!

Weston Revisted: Scholarly Reviews of "A professor, a president and a meteor"

Back in January 2011, I posted a review of Cathryn Prince's book, A professor, a president and a meteor. Up until recently, there have been few, if any, scholarly reviews of the work. The situation has changed with the publication, or upcoming publication, of three new reviews.

Ursula B. Marvin, Harvard-Smithsonian Center for Astrophysics, has written a detailed nine page review with references which is well worth the read.  It appears in the current issue of Meteoritics & Planetary Science 46, Nr 10, 1608-1616 (2011). For those who are not members of the Meteoritical Society and who do not receive the journal, the article can be previewed and purchased at I found Marvin's discussion of Nathaniel Bowditch's study on the Weston meteor and his relationship with President Jefferson to be particularly insightful in responding to Prince's comment that Jefferson asked Bowditch to "dispute Silliman's work on the Weston Fall."  As Marvin points out, Prince's comment is found on page 234 of the index to book, but the theme runs through the text.

Kristine C. Harper, Florida State University, has written a short two page book review, which offers some  some interesting comments disputing Prince's references to the work of Johannes Kepler. The review appears in the journal History: Reviews of New Books, 39:4, 112-113 (2011). The article can be previewed and purchased at

And lastly, I was honored to be invited to submit a shortened version of my Meteorite Manuscripts book review to Ambix, the scholarly journal of Society for the History of Alchemy and Chemistry, which should appear in the November issue.  More information on Ambix can be obtained at

As I mentioned in my first review, contrary to Prince, Silliman was not the first American scientist to have his work published in the French journal Annales de Chimie.  Robert Hare, his associate, had his paper on the oxygen-hydrogen blowpipe published in the journal five years before the Weston meteorite fall, and he received an international reputation as a result of his work. In her review, Marvin does not emphasize the importance of this point, initially stating that Silliman's report "was the first scientific paper in America (since Benjamin Franklin’s time) to win the admiration of the learned societies of Europe", but a few paragraphs later describing Hare as "a chemist who had gained international fame in 1801 as the inventor of the oxyhydrogen blowpipe."

In my opinion, all three reviews reach a consensus that Prince has overstated Silliman's contributions in the field of meteoritics.  An earlier biographer of Silliman, Chandros Michael Brown, had no such misconceptions about Silliman's accomplishments, stating at the beginning of his work, “but the bald truth is that Silliman’s contributions to science, as such, were negligible.” Although Prince used Brown's work as a reference, this fundamental perspective on the scientists life was completely ignored (see C. M. Brown, Benjamin Silliman. A Life in the Young Republic. Princeton, 1989, xiv). 

Prince is a well-intentioned author who is on firmer ground when discussing Silliman's real, long-lasting accomplishments. Silliman established the American Journal of Science and a school of chemistry at Yale, and he was an educator and promoter of science in the young American nation.

In the end, there is indeed a very real difference between capturing the imagination of the public and making fundamental scientific discoveries.

Royal Society Opens Archives of Publications

The Royal Society has announced that it is providing free access to all its journals 70 years or older.  This is of special interest to all historians conducting research on meteorites, since all of the material in the Philosophical Transactions of the Royal Society, first published in 1665, is available. Refer to the press release at for more information and for a link to begin a search of the journals.

Another source of historical information available from the Royal Society is its history of science journal, Notes & Records of the Royal Society. Content is normally restricted for one year, but after that period, the articles are freely accessible.

I was fortunate enough to have an article dealing with the Mooresfort meteorite published in December 2010. Since it was the 7th most-downloaded article for the year, it is freely accessible even though a year has not passed.

If you have not obtained a free copy, go to and scroll down to the link which reads "William Higgins at the Dublin Society, 1810–20: the loss of a professorship and a claim to the atomic theory", by Mark I. Grossman. Click on the link and you can download a pdf copy without charge.

Another article of mine entitled "Smithson Tennant: meteorites and the final trip to France" can be downloaded for free at

Early Use of Radium in the U.S. - George Barker's 1903 Columbia Lecture

Chemist and physicist George Frederick Barker (1835-1910) was instrumental in introducing radium to the US, and gave an important lecture entitled  “Radio-Activity in Chemistry” at Columbia University on March 19, 1903 [Columbia School of Mines Quarterly, 24, 267-302 (1903)]. For more information on Barker's life, see Edgar Fahs Smith National Academy of Sciences memoir (NAS Biographical Memoirs, 62).  You can download a copy by going to the NAS Biographical Memoirs webpage and clicking on the Barker, G. F. link.  Figures 1 and 2 display the front and back on an old cabinet photo of Barker that is in my collection.  Click on each photo to enlarge; click again to enlarge further.

In his talk, Barker showed three vials of radium salts, as well as a radiograph of a mouse, all of which he obtained from W. J. Hammer (1859-1934), author of the 1903 book, Radium and other radioactive substances.  Two radiographs of a mouse (one on a plate and the other caught in a trap) are shown in Hammer’s book (pages 38-39), but only one was used by Barker in his Columbia lecture (p. 290). Hammer worked for Thomas Edison, was an early experimenter with radium having obtained samples from Pierre and Marie Curie in 1902, and developed the infamous radium paint used on watch dials.  

Figure 3 displays a letter in my collection that was written by Barker to Hammer on March 15, 1903 in preparation for his Columbia lecture just a few days away, and is on University of PA Morgan Laboratory of Physics letterhead.  It reads in part:

“Dr. Chandler has asked me to repeat my talk before the Chem. Soc. of Columbia Univ. on Thursday evening (the 19th)… I would like to borrow for that evening your polonium metal & the three most active radium tubes.  Also, can you spare me the slide of the mouse (without the trap)?

Barker to Hammer, 3/15/1903. Copyright © Mark I. Grossman
Never mind the radiation concerns.  Seems like Barker did not want to disturb his audience with pictures of any dead mice caught in traps!

I am particularly fond of this letter because it not only mentions the radiographs that can be viewed in Hammer's book and Barker's lecture, it references Columbia chemist Charles Frederick Chandler (1836-1925) and the behind-the-scenes preparation for Barker's talk.

Correspondence of the Sydney Mining Museum - Part V - Meteorites

Another well-known correspondent of the Sydney Mining Museum was Friedrich Berwerth (1850-1918), who became head of the Mineralogical-Petrographical Department of the Natural History Museum in Vienna in 1895, and then curator of the Vienna meteorite collection in 1896 when Aristides Brezina (1848-1909) retired from the position in 1896.  A short biography with photo and signature of Berwerth can be found on the Naturhistorisches Museum Wien website and in Brandst├Ątter.

When George Card, curator of the Sydney Mining Museum, read about the fall of the Crumlin meteorite in the October 9, 1902 issue of Nature, he sent a communication to the journal which appeared in the February 12, 1903 issue (Figure 1 - click on image to enlarge, click again to enlarge further).  The note, entitled " A New South Wales Meteorite", reported on the fall of the 25-pound Mt. Browne meteorite on July 17, 1902.

 Figure 1:  Card's Feb. 1903 Mt. Browne Communication in Nature

The communication in Nature caught Berwerth's attention, because he wrote a letter to Card soon after it appeared (see Figures 2 and 3 - click to enlarge, click again to enlarge further).

 A rough translation of the German letter reads as follows:

Vienna, 29 March 1903

To Mr. G. W. Card

Dear Sir,

I read your notice about the Mount Browne meteorite that fell on 9 October 1902.  I am very interested in the stone.  Since you will break the stone in order to examine it I am taking the freedom to ask you to give me a sample for our large Viennese meteorite collection.  It is important in this place to receive meteorite material to study it.  I ask you kindly to leave me a sample to discover the value in case of a purchase.  I am sending you the new meteorite catalogue and some of my work about meteorites.

Hoping to hear from you, I am sincerely yours,
Prof. Friedrich Berwerth

Berwerth appears to have mixed up the date of the notice with the fall of the meteorite, which as noted occurred on July 17, 1902.  It is interesting to note the letterhead - Berwerth was definitely conducting official business.  Compare this letter with that of Brezina's in an earlier Meteorite Manuscripts post (Correspondence of the Sydney Mining Museum - Part IV).  Brezina's communication had no letterhead, and he was pursuing samples for his own collection after he retired.

Card published a subsequent communication in September 1903 and indicated that when the meteorite fell, it set a nearby hut on fire, although it did not hit the residence.  In addition, a photograph of the meteorite was included (Figures 4 and 5 - click to enlarge, click again to enlarge further).  A chemical analysis of the meteorite was conducted by H. P. White of the Geological Survey in 1904.

Berwerth's letter and the desire to obtain a sample of the Mount Browne meteorite for the famous Vienna collection underscores the importance of the Sydney Mining Museum holdings.
