Kachemak Bay State Park and Kachemak Bay Wilderness Park is a 400000 acre park in and around Kachemak Bay, Alaska.
 Kachemak Bay State Park was the first legislatively designated state park in the Alaska State Parks system.
 Kachemak Bay State Wilderness Park is the state's only legislatively designated wilderness park.
 There is no road access to most areas of the park, visitors normally fly in or travel by boat from Homer.
 Kachemak Bay is considered a critical habitat area due to the biodiversity in the area.
 Wildlife within the park includes marine mammals such as sea otters, sea lions, and whales, large land mammals such as moose and black bears, and numerous sea and land birds.
 Terrain consists of both rocky and sandy beaches, dense mountain forests, and higher up, glaciers, and icefields. Because of the rugged conditions and unpredictable coastal weather, visitors are advised to be prepared for sudden wind, rain, or snowstorms at any time of year, especially at higher elevations, and to file a travel plan with rangers.
 The park is mostly wild land, although there are a few cabins and semi-developed campgrounds.
 The park ranger station is located in Halibut Cove Lagoon.
 The Kachemak Bay area was infested with spruce bark beetles during the late 1990s, and thousands of acres of dead trees are still standing within the park.
 There has been at least one wildfire, the Mile 17 fire that burned areas of dead standing spruce on park land.
3198 Wallonia (1981 YH1) is a Mars-crossing asteroid discovered on 30 December 1981 by François Dossin at Haute-Provence Observatory.
 With an absolute magnitude (H) of 13, the asteroid is about ~10 km in diameter.
 It is one of the largest Mars-crossing asteroids as few Mars-crossing asteroids have an absolute magnitude brighter than 13.
The Haute-Provence Observatory (OHP, French: Observatoire de Haute-Provence ) is an astronomical observatory  in the southeast of France, about 90 km east of Avignon and 100 km north of Marseille.
 It was established in 1937 as a national facility for French astronomers. Astronomical observations began in 1943 using the 1.20 m telescope, and the first research papers based on observations made at the observatory were published in 1944.
 Foreign observers first used the observatory in 1949, when Geoffrey and Margaret Burbidge visited.
Chapman was born in Eccles, near Salford in England and began his advanced studies at a technical institute, now the University of Salford, in 1902.
 In 1904 at age 16, Chapman entered the University of Manchester.
 He competed for a scholarship to the university offered by his home county, and was the last student selected.
 Chapman later reflected, "I sometimes wonder what would have happened if I'd hit one place lower."
 He initially studied engineering in the department headed by Osborne Reynolds.
 Chapman was taught mathematics by Horace Lamb, the Beyer professor of mathematics, and J. E. Littlewood, who came from Cambridge in Chapman's final year at Manchester.
 Although he graduated with an engineering degree, Chapman had become so enthusiastic for mathematics that he stayed for one further year to take a mathematics degree.
 Following Lamb's suggestion, Chapman applied for a scholarship to Trinity College, Cambridge.
 He was at first awarded only a partial scholarship as a sizar (meaning that he obtained financial support by acting as a servant to other students), but from his second year onwards he received a full scholarship.
 He graduated as a wrangler in 1910.
 He began his research in pure mathematics under G. H. Hardy, but later that year was asked by Sir Frank Dyson to be his chief assistant at the Royal Greenwich Observatory.
The Old Town in Aarhus, Denmark (Danish: "Den Gamle By" ), is an open-air town museum located in the Aarhus Botanical Gardens.
 In 1914 the museum opened as the world's first open-air museum of its kind, concentrating on town culture rather than village culture, and to this day it remains one of just a few top rated Danish museums outside Copenhagen, serving more than 400,000 visitors pr.
 year.
 Today the museum consists of 75 historical buildings collected from 20 townships in all parts of the country.
 The town itself is the main attraction but most buildings are open for visitors; rooms are either decorated in the original historical style or organized into larger exhibits of which there are 5 regular with varying themes.
The Anglo-French Survey (1784–1790) refers to the survey to measure the relative situation of Greenwich Observatory and the Paris Observatory.
 The English operations, executed by William Roy, consisted of the measurements of bases at Hounslow Heath (1784) and Romney Marsh (1787), the measurements of the angles of the triangles (1787–1788) and finally the calculation of all the triangles (1788-1790).
 The survey is very significant as the first precise survey within Britain, and the forerunner of the work of the Ordnance Survey which was founded in 1791, one year after Roy's death.
Daniel E. Reichart is an American astronomer.
 He is best known for his ground breaking contributions to the field of gamma-ray bursts, most notably his discovery in 1999 of a signature similar to supernovae in the late-time afterglow of GRB 970228, the first burst for which an afterglow was observed.
 This discovery was named by Science magazine in 1999 as one of the top ten scientific breakthroughs of the year.
 Dr. Reichart additionally contributed to the development of SOAR (Southern Observatory for Astrophysical Research) in Cerro Pachon, Chile and also directs, along with his students, a group of six autonomous telescopes in Cerro Tololo Inter-American Observatory in Chile.
 He is currently a Bowman and Gordon Gray Distinguished Term Professor of Astronomy and Astrophysics and the director of the Morehead Observatory at The University of North Carolina at Chapel Hill.
Eleanor Margaret Burbidge ("née" Peachey), FRS (born August 12, 1919 in Davenport) is a British-born American astrophysicist, noted for original research and holding many administrative posts, including Director of the Royal Greenwich Observatory.
CL J1001+0220 is, as of 2016, the most distant known galaxy cluster.
 Discovered in 2016 by the Chandra X-ray Observatory in conjunction with the ESO's UltraVISTA telescope and the Atacama Large Millimeter Array, it has a redshift of z=2.506, placing it at a distance of 11.1 billion light-years from Earth.
 The galaxy cluster appears to be undergoing the transformation from a galaxy cluster that is still forming, a proto-cluster, to a mature cluster, and it is the first such cluster observed in this stage of its evolution.
 The cluster consists of seventeen galaxies, and nine of the eleven massive galaxies closest to its centre are starburst galaxies, forming new stars at the rate of about 3,400 Suns per year.
 In contrast, the Milky Way produces only the equivalent of one Sun per year, so these galaxies at the core of the cluster are producing stars at a rate three hundred times greater than the Milky Way on average.
 Other galaxy clusters at ten billion light years and closer have far less star formation, and this suggests that star formation slows down in large galaxies within clusters after the galaxies have already come together during the development of a galaxy cluster.
Antoine Émile Henry Labeyrie (born 12 May 1943) is a French astronomer, who held the Observational astrophysics chair at the Collège de France between 1991 and 2014, where he is currently professor emeritus.
 He is working with the Hypertelescope Lise association, which aims to develop an extremely large astronomical interferometer with spherical geometry that might theoretically show features on Earth-like worlds around other suns, as its president.
 He is a member of the French Academy of Sciences in the Sciences of the Universe ("sciences de l'univers") section.
 Between 1995 and 1999 he was director of the Haute-Provence Observatory.

Question: One of the first visitors of the Haute-Provence Observatory was born on which year?
Answer: 1919
