Extractions: Haldan Keffer Hartline December 22 March 17 ) was an American physiologist who was a cowinner (with George Wald and Ragnar Granit ) of the Nobel Prize in Physiology or Medicine for his work in analyzing the neurophysiological mechanisms of vision. Hartline began his study of retinal electrophysiology as a National Research Council Fellow at Johns Hopkins University Baltimore , receiving his M.D. in . After attending the universities of Leipzig and Munich as an Eldridge Johnson traveling research scholar, he became professor of biophysics and chairman of the department at Johns Hopkins in . He joined the staff of Rockefeller University New York City , in as professor of neurophysiology. Hartline investigated the electrical responses of the retinas of certain arthropods, vertebrates, and mollusks because their visual systems are much simpler than those of humans and are thus easier to study. He concentrated his studies on the eye of the horseshoe crab (Limulus polyphemus). Using minute electrodes in his experiments, he obtained the first record of the electrical impulses sent by a single optic nerve fibre when the receptors connected to it are stimulated by light. He found that the receptor cells in the eye are interconnected in such a way that when one is stimulated, others nearby are depressed, thus enhancing the contrast in light patterns and sharpening the perception of shapes. Hartline thus built up a detailed understanding of the workings of individual photoreceptors and nerve fibres in the retina, and he showed how simple retinal mechanisms constitute vital steps in the integration of visual information.

Extractions: ALFRED NOBEL (Fig.1) nacque a Stoccolma il 21 Ottobre 1883 e morì a Sanremo il 10 Dicembre 1896. Fu cittadino del mondo nel senso che passò la sua vita in quasi tutti i paesi dell'Europa. Nato in Svezia passò la sua adolescenza a San Pietroburgo in Russia, operò in molti paesi europei vivendo per lo più a Parigi. Trascorse gli ultimi anni della sua vita in Italia a San Remo dove abitò in una splendida dimora tuttora facente parte della fondazione Nobel. Parlava e scriveva correttamente in sei lingue, fu chimico ed ingegnere celebre per le sue redditizie attività industriali e per le sue invenzioni (compresa quella della dinamite). Ebbe interesse per la letteratura e la poesia e finanziò a più riprese movimenti pacifisti. Nel 1895, un anno prima della sua morte, elaborò il suo famoso testamento. Ma poichè diffidava degli avvocati, volle stendere da solo le sue ultime volontà, commettendo una serie di errori che furono superati solo grazie alla abilità del suo esecutore testamentario Ragnar Sohlman.

Extractions: Haldan Keffer Hartline was born in Bloomsburg, Pennsylvania, on December 22nd, 1903. His parents were teachers there in the State Normal School (now Bloomsburg State College) where he received his early education. His father, Daniel S. Hartline, was Professor of Biology, but a man whose wide interests also included Astronomy and Geology. It was through his father that Keffer became interested in Natural Sciences. Keffer Hartline attended Lafayette College in Easton, Pennsylvania, graduating in 1923 (B. Sc.). His college teacher of biology, Beverly W. Kunkel, encouraged him to undertake research; his first scientific paper concerned visual responses of land isopods. Summers at the Marine Biological Laboratory at Woods Hole added to his biological training; there he was especially influenced by Jacques Loeb, Selig Hecht, and Merkel H. Jacobs. In the autumn of 1923 he entered the Johns Hopkins School where he was encouraged to continue his research interest in vision in the Department of Physiology under E. K. Marshall and C. D. Snyder. Dr. Snyder let him use his Einthoven string galvanometer with which Hartline undertook the study of the retinal action potential using frogs, decerebrate cats and rabbits. He learned to obtain electroretinograms from intact animals, and recorded clearly recognizable retinal action potentials from human subjects. He also used intact insects for quantitative studies.

The origin of Herdleins, the early ancestors of present day Hartlines and Hartleins in America, was that region of Germany known as the State of Bavaria. and formerly a part of the "Upper Palatinate." The earliest recorded progenitor, Nikolaus Herdlein, lived in the district of Ansbach/Bavaria, in the village of Weigenheim, near Uffenheim. He is believed to have been born in Wallmersbach, which is located a few miles from Weigenheim. The village of Weigenheim is situated about twenty miles south-south-east of Wurzburg, and about a hundred miles east of the river Rhine. It is so small that it appears on only a few German maps. Nikolaus Herdlein was apparently the ancestor of all of the Hartlines who were in America in the eighteenth century, and of the majority of the present day Hartlines and Hartleins.
