History


1931–1941

The laboratory was founded on August 26, 1931, by
Ernest Lawrence Ernest Orlando Lawrence (August 8, 1901 – August 27, 1958) was an American nuclear physicist and winner of the Nobel Prize in Physics in 1939 for his invention of the cyclotron. He is known for his work on uranium-isotope separation fo ...

in 1939. Throughout the 1930s, Lawrence pushed to create larger and larger machines for physics research, courting private

for funding. He was the first to develop a large team to build big projects to make discoveries in basic research. Eventually these machines grew too large to be held on the university grounds, and in 1940 the lab moved to its current site atop the hill above campus. Part of the team put together during this period includes two other young scientists who went on to direct large laboratories:

. Lawrence's lab helped contribute to what have been judged to be the three most valuable technology developments of the war (the atomic bomb, proximity fuze, and radar). The cyclotron, whose construction was stalled during the war, was finished in November 1946. The Manhattan Project shut down two months later.


1951–2018

After the war, the Radiation Laboratory became one of the first laboratories to be incorporated into the Atomic Energy Commission (AEC) (now Department of Energy, DOE). The most highly classified work remained at Los Alamos, but the RadLab remained involved.
Edward Teller Edward Teller ( hu, Teller Ede; January 15, 1908 – September 9, 2003) was a Hungarian-American theoretical physicist who is known colloquially as "the father of the hydrogen bomb" (see the Teller–Ulam design), although he did not care for ...
suggested setting up a second lab similar to Los Alamos to compete with their designs. This led to the creation of an offshoot of the RadLab (now the Lawrence Livermore National Laboratory) in 1952. Some of the RadLab's work was transferred to the new lab, but some classified research continued at Berkeley Lab until the 1970s, when it became a laboratory dedicated only to unclassified scientific research. Shortly after the death of Lawrence in August 1958, the UC Radiation Laboratory (both branches) was renamed Lawrence Radiation Laboratory. The Berkeley location became Lawrence Berkeley Laboratory in 1971,University of California Office of the President
(accessed July 15, 2013).
although many continued to call it the RadLab. Gradually, another shortened form came into common usage, LBL. Its formal name was amended to Ernest Orlando Lawrence Berkeley National Laboratory in 1995, when "National" was added to the names of all DOE labs. "Ernest Orlando" was later dropped to shorten the name. Today, the lab is commonly referred to as Berkeley Lab. The Alvarez Physics Memos are a set of informal

Science mission

From the 1950s through the present, Berkeley Lab has maintained its status as a major international center for physics research, and has also diversified its research program into almost every realm of scientific investigation. Its mission is to solve the most pressing and profound scientific problems facing humanity, conduct basic research for a secure energy future, understand living systems to improve the environment, health, and energy supply, understand matter and energy in the universe, build and safely operate leading scientific facilities for the nation, and train the next generation of scientists and engineers The Laboratory's 20 scientific divisions are organized within six areas of research: Computing Sciences, Physical Sciences, Earth and Environmental Sciences, Biosciences, Energy Sciences, and Energy Technologies. Berkeley Lab has six main science thrusts: advancing integrated fundamental energy science, integrative biological and environmental system science, advanced computing for science impact, discovering the fundamental properties of matter and energy, accelerators for the future, and developing energy technology innovations for a sustainable future. It was Lawrence's belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab tradition that continues today. Berkeley Lab operates five major National User Facilities for the DOE Office of Science: # The

About 2,500 scientist-users carry out research at ALS every year. Berkeley Lab is proposing an upgrade of ALS which would increase the coherent flux of soft x-rays by two-three orders of magnitude. #The

Operations and governance

The University of California operates Lawrence Berkeley National Laboratory under a contract with the Department of Energy. The site consists of 76 buildings (owned by the U.S. Department of Energy) located on owned by the university in the Berkeley Hills. Altogether, the Lab has some 4,000 UC employees, of whom about 800 are students or postdocs, and each year it hosts more than 3,000 participating guest scientists. There are approximately two dozen DOE employees stationed at the laboratory to provide federal oversight of Berkeley Lab's work for the DOE. The laboratory director, Michael Witherell, is appointed by the university regents and reports to the university president. Although Berkeley Lab is governed by UC independently of the Berkeley campus, the two entities are closely interconnected: more than 200 Berkeley Lab researchers hold joint appointments as UC Berkeley faculty. The Lab's budget for the fiscal year 2019 was billion dollars.

He led efforts at the Lab that produced several technologies that radically improved efficiency: compact fluorescent lamps, low-energy refrigerators, and windows that trap heat. He established the Center for Building Science at the Lab, which developed into the Building Technology and Urban Systems Division. He developed the first energy-efficiency standards for buildings and appliances in California, which helped the state to sustain constant electricity use per capita, a phenomenon called the Rosenfeld effect. The Energy Efficiency and Environmental Impacts Division continues to set the research foundation for the national energy efficiency standards and works with China, India, and other countries to help develop their standards.
