The 1st photographs of a total solar eclipse

It’s been far too long since I indulged in a theme post. As total eclipse of the sun mania has struck the US, I’m jumping on the bandwagon too. The subject covers three of my favorite obsessions: the history of photography, the history of astronomy and historical firsts, all accompanied by that greatest of all obsessions, great high-resolution pictures.

William and Frederick Langenheim were born in Schöningen, Germany in 1807 and 1809 respectively. The were from a prominent family — their father Friedrich Wilhelm was mayor of Schöningen from 1808 until 1813 — but left what was then the Duchy of Brunswick in the 1830s. They immigrated to the United States and carved out careers as journalists. By 1842, they had opened a photography studio in Philadelphia.

The Langenheim daguerreotype studio quickly rose to preeminence in the city, thanks to the brothers’ great talent, inventiveness and embrace of new technology. In 1850 they debuted a new projectable photographic slides they called Hyalotypes. The device used to project them was a better-mousetrap version of the magic lantern which projected small drawn or painted images onto large screens. The stereopticon, as the Langenheim’s device became known, was a huge leap forward because it projected photographic images, not drawings, and because daguerreotypes capture even the most minute detail that cannot be seen with the naked eye, they could be magnified onto a screen at enormous dimensions, large enough that an auditorium of thousands could see spectacular images of, say, Niagara Falls or St. Peter’s Basilica without loss of resolution.

The brothers’ stereopticon had another feature that would prove momentous: a twin lense system that allowed the images to be faded one into the other, a smooth transition that far outshone the magic lantern’s choppy switch-overs. When they conceived of showing slides in an orderly progression, one dissolving into the other in a chronologically rational sequence, they unwittingly introduced the forerunner to the moving picture. The Langenheims charged people a dime to see pictures of natural, historical, architectural, artistic and scientific wonders projected on the big screen and the device was a huge hit.

A perfect subject for the stereopticon appeared in the skies over North America on May 26th, 1854. It was a total eclipse of the sun, the first one in the US since Louis Daguerre announced his new image-fixing process in 1839. The Langenheim brothers took eight daguerreotypes of the eclipse as it progressed. Only seven of them have survived. They are now in the permanent collection of the Metropolitan Museum of Art.

Although six other daguerreotypists and one calotypist are known to have documented the event, only these seven daguerreotypes survive. In the northern hemisphere, the moon always shadows the sun from right to left during a solar eclipse; these images therefore seem odd because they are, like all uncorrected daguerreotypes, reversed laterally as in a mirror.

It is noteworthy that these daguerreotypes are quite small, three exceptionally so. In order to produce any kind of image at all, the Langenheims were forced to use the smallest cameras available, since smaller cameras require proportionally less light and there was virtually no available light when the disk of the new moon eclipsed the largest part of the sun. The missing eighth image was probably made on the smaller plate size and showed nothing at all-a total eclipse.

As for our eclipse, now so easily captured by terrestrial and satellite technology, the National Archives in Washington, D.C. is going all out. They have secured safe solar telescopes from the National Air and Space Museum and will make them available to the public between 1:00 and 4:00PM so people can watch the eclipse up close and in total security. They’ve also created an exhibition, Solar Eclipses: Past and Present, from their pictures and records of other eclipses.

For all you eclipse watchers out there, don’t forget your protective eyewear. If you don’t have the opportunity to view the eclipse in person, you can follow its whole extraordinary path on NASA’s website.

In my undergraduate days I was a fan of the epidiascope.

Washington D.C., United States, Planet Earth, Current Time Zone offset: GMT/UTC – 4:00. Therefore, “between 1:00 and 4:00PM” should be 5 to 8PM UTC.

However, the ‘real thing’ seems to take place from 18:16 GMT (Lincoln Beach, Oregon) to 19:48 GMT (McClellanville, South Carolina), with a corridor of 110 kilometers (68.35 miles).

“On the day of the new moon, in the month of Hiyar, the sun was put to shame, and went down in the daytime, with Mars in attendance.”
——————-

“An astronomical event recorded on a clay tablet found in 1948 in the ancient city of Ugarit, in what is now Syria, was identified as a description of a total solar eclipse that occurred on May 3rd, 1375 BC. The dating of ancient solar eclipses provides reference points to fix the long-term evolution of angular momentum in the Earth-Moon system.

A new historical dating of the tablet, and mention in the text of the visibility of the planet Mars during the eclipse as well as the month in which it occurred shows that the recorded eclipse in fact occurred on March 5th, 1223 BC. This new date implies that the secular deceleration of the Earth’s rotation has changed very little during the past 3000 years.”

Found on the internet:

Joel 2:31

“The sun shall be turned to darkness, and the moon to blood, before the great and terrible day of the LORD comes.”

According to Stephenson, the text in Joel is the best reference in the Old Testament of a total eclipse of the sun and a total eclipse of the moon, which occurred at different times. Some scholars use this reference to the solar eclipse to date the book of Joel. Gaebelein, for instance, dates the book of Joel in the ninth century B.C. This date, according to Gaebelein, “is abundantly verified by different facts found in the book itself.” One of them is the solar eclipse that occurred on August 15, 831 B.C.

However, as I showed in my article on Joel (1987:125-130), the book of Joel was written in the post-exilic period. John Bright believes that Joel was probably composed in the Persian Period (1981:434). Stephenson associates the eclipse mentioned in Joel with the eclipse that occurred in 357 B.C. Stephenson said that astronomical evidence and Joel’s statement that the sun would be “turned into darkness” in Judah, suggests that Joel was a witness of the eclipse that occurred on February 29. 357 B.C.”

Was one of the most moving things I’ve ever seen. Perhaps only passed by the birth of my children.

If “daguerreotypes capture even the most minute detail that cannot be seen with the naked eye” (something I did not know), I wonder why I’ve never read about historical or forensic investigations being made by microscopic examination of daguerrotypes? Every reproduction of a daguerrotype that I’ve seen has been small—actual size at best. If tiny details are actually preserved, I would think that enlargements would be revealing.

Is it the resolution of the lens that is the truly limiting factor?
