Question: Where did Leona Woods's husband die?

Knowledge 1: Leona Woods
Leona Harriet Woods (August 9, 1919 – November 10, 1986), later known as Leona Woods Marshall and Leona Woods Marshall Libby, was an American physicist who helped build the first nuclear reactor and the first atomic bomb.At age 23, she was the youngest and only female member of the team which built and experimented with the world's first nuclear reactor (then called a "pile"), Chicago Pile-1, in a project led by her mentor Enrico Fermi.In particular, Woods was instrumental in the construction and then utilization of geiger counters for analysis during experimentation.She was the only woman present when the reactor went critical.She worked with Fermi on the Manhattan Project, and, together with her first husband John Marshall, she subsequently helped solve the problem of xenon poisoning at the Hanford plutonium production site, and supervised the construction and operation of Hanford's plutonium production reactors.After the war, she became a fellow at Fermi's Institute for Nuclear Studies.She later worked at the Institute for Advanced Study in Princeton, New Jersey, the Brookhaven National Laboratory, and New York University, where she became a professor in 1962.Her research involved high-energy physics, astrophysics and cosmology.In 1966 she divorced Marshall and married Nobel laureate Willard Libby.She became a professor at the University of Colorado, and a staff member at RAND Corporation.In later life she became interested in ecological and environmental issues, and she devised a method of using the isotope ratios in tree rings to study climate change.She was a strong advocate of food irradiation as a means of killing harmful bacteria. [SEP] Knowledge 2: Willard Libby
Willard Frank Libby (December 17, 1908 – September 8, 1980) was an American physical chemist noted for his role in the 1949 development of radiocarbon dating, a process which revolutionized archaeology and palaeontology.For his contributions to the team that developed this process, Libby was awarded the Nobel Prize in Chemistry in 1960.A 1927 chemistry graduate of the University of California, Berkeley, from which he received his doctorate in 1933, he studied radioactive elements and developed sensitive Geiger counters to measure weak natural and artificial radioactivity.During World War II he worked inthe Manhattan Project's Substitute Alloy Materials (SAM) Laboratories at Columbia University, developing the gaseous diffusion process for uranium enrichment.After the war, Libby accepted professorship at the University of Chicago's Institute for Nuclear Studies, where he developed the technique for dating organic compounds using carbon-14.He also discovered that tritium similarly could be used for dating water, and therefore wine.In 1950, he became a member of the General Advisory Committee (GAC) of the Atomic Energy Commission (AEC).He was appointed a commissioner in 1954, becoming its sole scientist.He sided with Edward Teller on pursuing a crash program to develop the hydrogen bomb, participated in the Atoms for Peace program, and defended the administration's atmospheric nuclear testing.Libby resigned from the AEC in 1959 to become Professor of Chemistry at University of California, Los Angeles (UCLA), a position he held until his retirement in 1976.In 1962, he became the Director of the University of California statewide Institute of Geophysics and Planetary Physics (IGPP).He started the first Environmental Engineering program at UCLA in 1972, and as a member of the California Air Resources Board, he worked to develop and improve California's air pollution standards.

The Ancient Egyptian artisan Sennedjem lived in Set Maat( translated as" The Place of Truth"), contemporary Deir el- Medina, on the west bank of the Nile, opposite Thebes, during the reigns of Seti I and Ramesses II.Sennedjem had the title" Servant in the Place of Truth".He was buried along with his wife, Iyneferti, and family in a tomb in the village necropolis.His tomb was discovered January 31, 1886.When Sennedjem's tomb was found, in it there was regular furniture from his home, including a stool and a bed, which he actually used when he was alive.His titles included Servant in the Place of Truth, meaning that he worked on the excavation and decoration of the nearby royal tombs.

[SEP] Knowledge 2: Place of birth
The place of birth( POB) or birthplace is the place where a person was born.This place is often used in legal documents, together with name and date of birth, to uniquely identify a person.As a general rule with respect to passports, the place of birth is determined to be the country that currently has" sovereignty" over the actual place of birth, regardless of when the birth actually occurred.The place of birth is not necessarily the place where the parents of the new baby live.If the baby is born in a hospital in another place, that place is the place of birth.In many countries, this also means that the government requires that the birth of the new baby is registered in the place of birth.Some countries place less or no importance on the place of birth, instead using alternative geographical characteristics for the purpose of identity documents.For example, Sweden has used the concept of" födelsehemortdomicile of birth") since 1947.This means that the domicile of the baby's mother is the registered place of birth.The location of the maternity ward or other physical birthplace is considered unimportant.Similarly, Switzerland uses the concept of" Heimatortlieu d'origineluogo d'origineplace of origin" in German, French and Italian respectively).A child born to Swiss parents is automatically assigned the place of origin of the parent with the same last name, so the child either gets their mother's or father's place of origin.A child born to one Swiss parent and one foreign parent acquires the place of origin of their Swiss parent.In a Swiss passport and identity card, the holder's place of origin is stated, not their place of birth.In some countries( primarily in the Americas), the place of birth automatically determines the nationality of the baby, a practice often referred to by the Latin phrase" jus soli".Almost all countries outside the Americas instead attribute nationality based on the nationality( ies) of the baby's parents( referred to as" jus sanguinis").There can be some confusion regarding the place of birth if the birth takes place in an unusual way: when babies are born on an airplane or at sea, difficulties can arise.The place of birth of such a person depends on the law of the countries involved, which include the nationality of the plane or ship, the nationality( ies) of the parents and/ or the location of the plane or ship( if the birth occurs in the territorial waters or airspace of a country).Some administrative forms may request the applicant's" country of birth".It is important to determine from the requester whether the information requested refers to the applicant's" place of birth" or" nationality at birth".For US citizens born abroad who under the US Constitution acquire US citizenship at the time of birth, the nationality at birth will be USA( American), while the place of birth would be the country in which the actual birth takes place.
