University of California, Los Angeles in the context of "Preston Cloud"

Harold Kelley (February 16, 1921 – January 29, 2003) was an American social psychologist and professor of psychology at the University of California, Los Angeles. His major contributions have been the development of interdependence theory (with John Thibaut), the early work of attribution theory, and a lifelong interest in understanding close relationships processes. A Review of General Psychology survey, published in 2002, ranked Kelley as the 43rd most cited psychologist of the 20th century.

Francis Rory Peregrine "Perry" Anderson (born 11 September 1938) is a British intellectual, political philosopher, historian and essayist. His work ranges across historical sociology, intellectual history, and cultural analysis. What unites Anderson's work is a preoccupation with Western Marxism.

Anderson is perhaps best known as the moving force behind the New Left Review. He is Professor of History and Sociology at the University of California, Los Angeles (UCLA). Anderson has written many books, most recently Different Speeds, Same Furies: Powell, Proust and other Literary Forms and Disputing Disaster: A Sextet on the Great War. He is the brother of political scientist Benedict Anderson (1936–2015).

Jared Mason Diamond (born September 10, 1937) is an American scientist, historian, and author. In 1985 he received a MacArthur Genius Grant, and he has written hundreds of scientific and popular articles and books. His best known is Guns, Germs, and Steel (1997), which received multiple awards including the 1998 Pulitzer Prize for general nonfiction. In 2005, Diamond was ranked ninth on a poll by Prospect and Foreign Policy of the world's top 100 public intellectuals.

Originally trained in biochemistry and physiology, Diamond has published in many fields, including anthropology, ecology, geography, and evolutionary biology. In 1999, he received the National Medal of Science, an honor bestowed by the President of the United States and the National Science Foundation. He was a professor of geography at UCLA until his retirement in 2024. Anthropologists have criticized his work as “shallow,” saying he overemphasizes geography and climate.

Laird A. Thompson (born 6 September 1947), is a professor emeritus of astronomy at the University of Illinois Urbana-Champaign. Thompson graduated with a B.A. in both physics and astronomy from the University of California, Los Angeles in 1969. He received his Ph.D. in astronomy from the University of Arizona in 1974.He is professionally associated with the International Astronomical Union, the American Astronomical Society, the Astronomical Society of the Pacific, the International Society for Optical Engineering, and has served as an adjunct member of the Center for Adaptive Optics.

The third cholera pandemic (1846–1860) was the third major outbreak of cholera originating in India in the 19th century that reached far beyond its borders, which researchers at University of California, Los Angeles (UCLA) believe may have started as early as 1837 and lasted until 1863. In the Russian Empire, more than one million people died of cholera. In 1853–1854, the epidemic in London claimed over 10,000 lives, and there were 23,000 deaths for all of Great Britain. This pandemic was considered to have the highest fatalities of the 19th-century epidemics.

It had high fatalities among populations in Asia, Europe, Africa and North America. In 1854, which was considered the worst year, 23,000 people died in Great Britain.

The University of California (UC) is a public land-grant research university system in the U.S. state of California. Headquartered in Oakland, the system is composed of its ten campuses at Berkeley, Davis, Irvine, Los Angeles, Merced, Riverside, San Diego, San Francisco, Santa Barbara, and Santa Cruz, along with numerous research centers and academic centers abroad. The system is the state's land-grant university.

In 1900, UC was one of the founders of the Association of American Universities and since the 1970s seven of its campuses, in addition to Berkeley, have been admitted to the association. Berkeley, Davis, Irvine, Los Angeles, Santa Barbara, Santa Cruz, Riverside, and San Diego are considered Public Ivies, making California the state with the most universities in the nation to hold the title. UC campuses have large numbers of distinguished faculty in almost every academic discipline, with UC faculty and researchers having won 75 Nobel Prizes as of 2025.

Peter Nielsen Ladefoged (/ˈlædɪfoʊɡɪd/ LAD-if-oh-ghid, Danish: [ˈpʰe̝ˀtɐ ˈne̝lsn̩ ˈlɛːðəˌfoːð̩]; 17 September 1925 – 24 January 2006) was a British linguist and phonetician.He was Professor of Phonetics at University of California, Los Angeles (UCLA), where he taught from 1962 to 1991. His book A Course in Phonetics is a common introductory text in phonetics, and The Sounds of the World's Languages (co-authored with Ian Maddieson) is widely regarded as a standard phonetics reference. Ladefoged also wrote several books on the phonetics of African languages. Prior to UCLA, he was a lecturer at the universities of University of Edinburgh in Scotland (1953–59, 1960–61) and the University of Ibadan in Nigeria (1959–60).

Terence Chi-Shen Tao FAA FRS (born 17 July 1975) is an Australian and American mathematician. He is a Fields medalist and a professor of mathematics at the University of California, Los Angeles (UCLA), where he holds the James and Carol Collins Chair in the College of Letters and Sciences. His research includes topics in harmonic analysis, partial differential equations, algebraic combinatorics, arithmetic combinatorics, geometric combinatorics, probability theory, compressed sensing, analytic number theory and the applications of artificial intelligence in mathematics.

Tao was born to Chinese immigrant parents and raised in Adelaide, South Australia. Tao won the Fields Medal in 2006 and won the Royal Medal and Breakthrough Prize in Mathematics in 2014, and is a 2006 MacArthur Fellow. Tao has been the author or co-author of over three hundred research papers, and is widely regarded as one of the greatest living mathematicians.

The eocyte hypothesis in evolutionary biology proposes that the eukaryotes originated from a group of prokaryotes called eocytes (later classified as Thermoproteota, a group of archaea). After his team at the University of California, Los Angeles discovered eocytes in 1984, James A. Lake formulated the hypothesis as "eocyte tree" that proposed eukaryotes as part of archaea. Lake hypothesised the tree of life as having only two primary branches: prokaryotes, which include Bacteria and Archaea, and karyotes, that comprise Eukaryotes and eocytes. Parts of this early hypothesis were revived in a newer two-domain system of biological classification which named the primary domains as Archaea and Bacteria.

Lake's hypothesis was based on an analysis of the structural components of ribosomes. It was largely ignored, being overshadowed by the three-domain system which relied on more precise genetic analysis. In 1990, Carl Woese and his colleagues proposed that cellular life consists of three domains—Eucarya, Bacteria, and Archaea – based on the ribosomal RNA sequences. The three-domain concept was widely accepted in genetics, and became the presumptive classification system for high-level taxonomy, and was promulgated in many textbooks.

James A. Lake (born August 10, 1941) is an American evolutionary biologist and a Distinguished Professor of Molecular, Cell, and Developmental Biology and of Human Genetics at UCLA. Lake is best known for the New Animal Phylogeny and for the first three-dimensional structure of the ribosome. He has also made significant contributions to understanding genome evolution across all kingdoms of life, including discovering informational and operational genes, elucidating the complexity hypothesis for gene transfer, rooting the tree of life, and understanding the early transition from prokaryotic to eukaryotic life.
