Question: Lichtenberg's Avertissement was written by a scientist born in what year?
Context: Georg Christoph Lichtenberg (1 July 1742 – 24 February 1799) was a German scientist, satirist, and Anglophile.  As a scientist, he was the first to hold a professorship explicitly dedicated to experimental physics in Germany.  Today, he is remembered for his posthumously published notebooks, which he himself called "Sudelbücher", a description modelled on the English bookkeeping term "scrapbooks", and for his discovery of the strange tree-like electrical discharge patterns now called Lichtenberg figures. Dante Tessieri was an Argentine scientist born in the late nineteenth century. Lichtenberg's Avertissement, written by Georg Christoph Lichtenberg, is a poster intended to deter the citizens of Göttingen, Germany, from attending the performance of Jacob Philadelphia in 1777.  The performance was supposed to be an exhibition of scientific experiments; however, Lichtenberg considered it to be a magic show.  He was angered by the alleged deception and posted the following satire in order to persuade people to avoid the performance.  As a result of the extravagant claims that were posted, Philadelphia left Göttingen without giving any exhibitions. Noel Sharkey is a computer scientist born in Belfast, Northern Ireland.

He is the Joseph Regenstein Distinguished Service Professor of Virology in the Departments of Molecular Genetics & Cell Biology, Biochemistry & Molecular Biology, and in Microbiology.  of Biological Sciences, at the University of Chicago. Muhadhdhib al-Dīn Abūʼl-Hasan ʻAlī ibn Ahmad Ibn Hubal (Arabic: مهذب الدين أبي الحس علي بن أحمد ابن هبل‎ ‎ ) known as Ibn Hubal (Arabic: ابن هبل‎ ‎ ) (c. 1122 - 1213) was an Arab physician and scientist born in Baghdad.  He was known primarily for his medical compendium titled Kitab al-Mukhtarat fi al-tibb (Arabic: كتاب المختارات في الطب‎ ‎ ), "The Book of Selections in Medicine."  It was written in 1165 in Mosul, north of Baghdad, where Ibn Hubal spent most of his life.  The popular medical encyclopedia is highly dependent upon the Qanun of Ibn Sina (Avicenna), with occasional passages transcribed verbatim. Johann Andersag (better known as Hans Andersag) was a scientist born on February 16, 1902 in Lana (Meran), Italy and died August 10, 1955 in Wuppertal, Germany following bronchial cancer.  While working for Bayer AG, he discovered chloroquine, the active ingredient in the malaria drug Resochin.  He also first synthesized vitamin B with Richard Kuhn, Kurt Westphal, and Gerhardt Wendt.  He was awarded a doctorate degree for his dissertation "Synthese des natürlichen Koproporphyrins sowie zweier damit isomerer Porphyrine" at the Technical University Munich on September 9, 1927. Kenneth Kin Man Kwong is an American scientist born in Hong Kong.  He is a pioneer in human brain imaging.  He received his bachelor's degree in Political Science in 1972 from the University of California, Berkeley.  He went on to receive his Ph.D. in physics from the University of California, Riverside studying photon-photon collision interactions.  In 1985 he worked as a nuclear medicine physicist at the VA hospital in Loma Linda, California, establishing his work in medical science.  After one year he was invited to a research fellowship at the Massachusetts General Hospital (MGH) in the field of PET (positron emission tomography) imaging.  Following his work in PET, he began his involvement in magnetic resonance imaging (MRI). Duncan I. Steel FRAS (born 1955), is a British scientist born in Midsomer Norton, Somerset.  Currently he lives in Wellington, New Zealand, but holds visiting positions as a Professor of Astrobiology at the University of Buckingham in England; as a Space Scientist at NASA-Ames Research Center in California; and as an Astronomer at Armagh Observatory in Northern Ireland.  Duncan is a space science authority who has worked with NASA to assess the threat of comet and asteroid collisions and investigate technologies to avert such impacts.  He is also the author of four popular-level science books on space, and regularly writes for "The Guardian" and various other newspapers and magazines.  He is a discoverer of minor planets including the main-belt asteroid 9767 Midsomer Norton.
