Gettysburg’s Unknown Soldier

This item appeared in the Philadelphia Inquirer on Oct. 19, 1863:

Whose Father Was He?

After the battle of Gettysburg, a Union soldier was found in a secluded spot on the field, where, wounded, he had laid himself down to die. In his hands, tightly clasped, was an ambrotype containing the portraits of three small children, and upon this picture his eyes, set in death, rested. The last object upon which the dying father looked was the image of his children, and as he silently gazed upon them his soul passed away. How touching! how solemn! What pen can describe the emotions of this patriot-father as he gazed upon these children, so soon to be made orphans! Wounded and alone, the din of battle still sounding in his ears, he lies down to die. His last thoughts and prayers are for his family. He has finished his work on earth; his last battle has been fought; he has freely given his life to his country; and now, while his life’s blood is ebbing, he clasps in his hands the image of his children, and, commending them to the God of the fatherless, rests his last lingering look upon them.

When, after the battle, the dead were being buried, this soldier was thus found. The ambrotype was taken from his embrace, and since been sent to this city for recognition. Nothing else was found upon his person by which he might be identified. His grave has been marked, however, so that if by any means this ambrotype will lead to his recognition he can be disinterred. This picture is now in the possession of Dr. Bourns, No. 1104 Spring Garden [Street], of this city, who can be called upon or addressed in reference to it. The children, two boys and a girl, are, apparently, nine, seven and five years of age, the boys being respectively the oldest and youngest of the three. The youngest boy is sitting in a high chair, and on each side of him are his brother and sister. The eldest boy’s jacket is made from the same material as his sister’s dress. These are the most prominent features of the group. It is earnestly desired that all the papers in the country will draw attention to the discovery of this picture and its attendant circumstances, so that, if possible, the family of the dead hero may come into possession of it. Of what inestimable value it will be to these children, proving, as it does, that the last thoughts of their dying father was for them, and them only.

The description was reprinted in the American Presbyterian on Oct. 29, where it was read by Philinda Humiston of Portville, N.Y., who had not heard from her husband since Gettysburg. She identified the unknown soldier as Sgt. Amos Humiston of Company C, 154th New York Volunteers. His body was removed to the Gettysburg National Cemetery, and the outpouring of sympathy for his children led to the establishment of a Soldier’s Orphan’s Home in Gettysburg in 1866.

If the nth term of the Fibonacci series is prime, then n also is prime (where n > 4). For example, the 17th term, 1597, is prime, and 17 is prime.

05/27/2017 UPDATE: Further to the first series, 1979339333 is also prime! (Thanks, Alon.)

Food for Tomorrow

By 1941 Russian botanist Nikolai Vavilov had created the largest seed bank in the world, a collection of 400,000 seeds, roots, and fruits whose genetic material held the future of Soviet agriculture. Unfortunately it was located in Leningrad, which Hitler encircled that summer and began to starve.

The siege of Leningrad lasted two years and cost more than a million lives, and Vavilov’s scientists endured it surrounded by edible plants. “As they slowly starved, they refused to eat from any of their collection containers of rice, peas, corn and wheat,” two survivors remembered in 1993. “They chose torment and death in order to preserve Vavilov’s gene bank.”

The collection filled 16 rooms, in which no one was allowed to remain alone. Workers stored potatoes in the basement and guarded them in shifts, “numb with cold and emaciated from hunger.” Botanist Dmitri Ivanov died preserving thousands of packets of rice; peanut specialist Alexander Stchukin died at his writing table. In all, nine scientists and workers chose to die of starvation rather than eat the plants. Vavilov himself died in a labor camp in 1943, but today his bank is the largest collection of fruits and berries in the world.

Dante’s Dentist

http://www.google.com/patents/US353403

In 1886 Levi Deckard of Pennsylvania patented an electrified dental chair to provide “electricity as an anaesthetic” to people undergoing tooth extractions and other painful operations.

The dentist operates a foot-driven generator, the patient grips the electrodes, “and the desired shock is produced.” Deckard doesn’t explain why he thinks this will stop pain — but it certainly must be distracting.

The Duluth Speech

http://commons.wikimedia.org/wiki/File:View_in_the_city_of_Duluth,_Minn.--Superior_St,_from_Robert_N._Dennis_collection_of_stereoscopic_views.jpg

In 1871 the House of Representatives was considering subsidizing railroads to serve the Midwest, including tiny Duluth, Minn. Kentucky representative J. Proctor Knott rose, produced a bucket of sarcasm, and began ladling:

Duluth! The word fell upon my ear with peculiar and indescribable charm, like the gentle murmur of a low fountain stealing forth in the midst of roses, or the soft, sweet accents of an angel’s whisper, in the bright joyous dream of sleeping innocence. Duluth: ‘Twas the name for which my soul had panted for years, as the hart panteth for water-brooks. But where was Duluth? Never, in all my limited reading, had my vision been gladdened by seeing the celestial word in print. And I felt a profounder humiliation in my ignorance, that its dulcet syllables had never before ravished my delighted ear. …

Nevertheless, I was confident it existed somewhere, and that its discovery would constitute the crowning glory of the present century, if not of all modern times. I knew it was bound to exist in the very nature of things; that the symmetry and perfection of our planetary system would be incomplete without it, that the elements of material nature would long since have resolved themselves back into original chaos if there had been such a hiatus in creation as would have resulted from leaving out Duluth.

In fact, sir, I was overwhelmed with the conviction that Duluth not only existed somewhere, but that wherever it was, it was a great and a glorious place. I was convinced that the greatest calamity that ever befell the benighted nations of the ancient world was in their having passed away without a knowledge of the actual existence of Duluth; that their fabled Atlantis, never seen save by the hallowed vision of inspired poesy, was in fact but another name for Duluth; that the golden orchard of the Hesperides was but a poetical synonym for the beer gardens in the vicinity of Duluth.

I was certain that Herodotus had died a miserable death because in all his travels and with all his geographical research he had never heard of Duluth. I knew that if the immortal spirit of Homer could look down from another heaven than that created by his own celestial genius upon the long lines of pilgrims from every nation of the earth to the gushing fountain of poesy opened by the touch of his magic wand, if he could be permitted to behold the vast assemblage of grand and glorious productions of the lyric art called into being by his own inspired strains, he would weep tears of bitter anguish that instead of lavishing all the stories of his mighty genius upon the fall of Troy it had not been his more blessed lot to crystallize in deathless song the rising glories of Duluth.

Yet, sir, had it not been for this map, kindly furnished me by the Legislature of Minnesota, I might have gone down to my obscure and humble grave in an agony of despair, because I could nowhere find Duluth. Had such been my melancholy fate, I have no doubt that with the last feeble pulsation of my breaking heart, with the last faint exhalation of my fleeting breath I should have whispered, ‘Where is Duluth?’

The bill was defeated. See American Notes.
