Frank Friedman Oppenheimer (August 14, 1912 – February 3, 1985) was an American particle physicist, cattle rancher, professor of physics at the University of Colorado, and the founder of the Exploratorium in San Francisco.
Particle physics is a branch of physics that studies the nature of the particles that constitute matter and radiation. Although the word particle can refer to various types of very small objects, particle physics usually investigates the irreducibly smallest detectable particles and the fundamental interactions necessary to explain their behaviour. By our current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. Thus, modern particle physics generally investigates the Standard Model and its various possible extensions, e.g. to the newest "known" particle, the Higgs boson, or even to the oldest known force field, gravity.
The University of Colorado system is a system of public universities in Colorado consisting of four campuses: University of Colorado Boulder, University of Colorado Colorado Springs, University of Colorado Denver in downtown Denver and at the Anschutz Medical Campus in Aurora. It is governed by the elected, nine-member Board of Regents of the University of Colorado.
The Exploratorium is a museum in San Francisco that allows visitors to explore the world through science, art, and human perception. Its mission is to create inquiry-based experiences that transform learning worldwide. It has been described by the New York Times as the most important science museum to have opened since the mid-20th century, an achievement attributed to "the nature of its exhibits, its wide-ranging influence and its sophisticated teacher training program". Characterized as "a mad scientist's penny arcade, a scientific funhouse, and an experimental laboratory all rolled into one", the participatory nature of its exhibits and its self-identification as a center for informal learning has led to it being cited as the prototype for participatory museums around the world.
A younger brother of renowned physicist J. Robert Oppenheimer, Frank Oppenheimer conducted research on aspects of nuclear physics during the time of the Manhattan Project, and made contributions to uranium enrichment. After the war, Oppenheimer's earlier involvement with the American Communist Party placed him under scrutiny, and he resigned from his physics position at the University of Minnesota. Oppenheimer was a target of McCarthyism and was blacklisted from finding any physics teaching position in the United States until 1957, when he was allowed to teach science at a high school in Colorado. This rehabilitation allowed him to gain a position at the University of Colorado teaching physics. In 1969, Oppenheimer founded the Exploratorium in San Francisco, and he served as its first director until his death in 1985.
Julius Robert Oppenheimer was an American theoretical physicist and professor of physics at the University of California, Berkeley. Oppenheimer was the wartime head of the Los Alamos Laboratory and is among those who are credited with being the "father of the atomic bomb" for their role in the Manhattan Project, the World War II undertaking that developed the first nuclear weapons. The first atomic bomb was successfully detonated on July 16, 1945, in the Trinity test in New Mexico. Oppenheimer later remarked that it brought to mind words from the Bhagavad Gita: "Now I am become Death, the destroyer of worlds." In August 1945, the weapons were used in the atomic bombings of Hiroshima and Nagasaki.
The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District; Manhattan gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion. Over 90% of the cost was for building factories and to produce fissile material, with less than 10% for development and production of the weapons. Research and production took place at more than 30 sites across the United States, the United Kingdom, and Canada.
The University of Minnesota, Twin Cities is a public research university in Minneapolis and Saint Paul, Minnesota. The Minneapolis and St. Paul campuses are approximately 3 miles (4.8 km) apart, and the St. Paul campus is actually in neighboring Falcon Heights. It is the oldest and largest campus within the University of Minnesota system and has the sixth-largest main campus student body in the United States, with 50,943 students in 2018-19. The university is the flagship institution of the University of Minnesota system, and is organized into 19 colleges and schools, with sister campuses in Crookston, Duluth, Morris, and Rochester.
Frank Friedman Oppenheimer was born in 1912 in New York City, to Julius Oppenheimer and Ella Friedman. 30During his childhood, he studied painting. He also studied the flute under nationally known teacher George Barrera, becoming competent enough at the instrument to consider a career as a flautist. :
The City of New York, usually called either New York City (NYC) or simply New York (NY), is the most populous city in the United States. With an estimated 2018 population of 8,398,748 distributed over a land area of about 302.6 square miles (784 km2), New York is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, the largest metropolitan area in the world by urban landmass and one of the world's most populous megacities, with an estimated 19,979,477 people in its 2018 Metropolitan Statistical Area and 22,679,948 residents in its Combined Statistical Area. A global power city, New York City has been described as the cultural, financial, and media capital of the world, and exerts a significant impact upon commerce, entertainment, research, technology, education, politics, tourism, art, fashion, and sports. The city's fast pace has inspired the term New York minute. Home to the headquarters of the United Nations, New York is an important center for international diplomacy.
Frank began his schooling at the Ethical Culture School, where he attended until seventh grade. The remainder of his high school education was completed at Fieldston School in Riverdale; a school operated by the Ethical Culture Society.
Frank eventually followed the advice of his older brother Robert, and became a professional physicist. He entered into studies at Johns Hopkins University in 1930, graduating three years later with a BS in physics.Afterwards, Frank studied for a year and a half at the Cavendish Laboratory in Cambridge, England, where he also earned a pilot's license. In 1935, he worked on the development of nuclear particle counters at the Institute di Arcetri in Florence, Italy.
Johns Hopkins University is a private research university in Baltimore, Maryland. Founded in 1876, the university was named for its first benefactor, the American entrepreneur, abolitionist, and philanthropist Johns Hopkins. His $7 million bequest —of which half financed the establishment of Johns Hopkins Hospital—was the largest philanthropic gift in the history of the United States up to that time. Daniel Coit Gilman, who was inaugurated as the institution's first president on February 22, 1876, led the university to revolutionize higher education in the U.S. by integrating teaching and research. Adopting the concept of a graduate school from Germany's ancient Heidelberg University, Johns Hopkins University is considered the first research university in the United States. Over the course of several decades, the university has led all U.S. universities in annual research and development expenditures. In fiscal year 2016, Johns Hopkins spent nearly $2.5 billion on research.
The Cavendish Laboratory is the Department of Physics at the University of Cambridge, and is part of the School of Physical Sciences. The laboratory was opened in 1874 on the New Museums Site as a laboratory for experimental physics and is named after the British chemist and physicist Henry Cavendish. The laboratory has had a huge influence on research in the disciplines of physics and biology.
In the physical sciences, subatomic particles are particles much smaller than atoms. The two types of subatomic particles are: elementary particles, which according to current theories are not made of other particles; and composite particles. Particle physics and nuclear physics study these particles and how they interact. The idea of a particle underwent serious rethinking when experiments showed that light could behave like a stream of particles as well as exhibiting wave-like properties. This led to the new concept of wave–particle duality to reflect that quantum-scale "particles" behave like both particles and waves. Another new concept, the uncertainty principle, states that some of their properties taken together, such as their simultaneous position and momentum, cannot be measured exactly. In more recent times, wave–particle duality has been shown to apply not only to photons but to increasingly massive particles as well.
While completing his PhD work at the California Institute of Technology, Oppenheimer became engaged to Jaquenette Quann, an economics student at the University of California, Berkeley; she was also active in the Young Communist League. In spite of Robert's recommendations,Frank and Jackie were married in 1936 and soon both joined the American Communist Party, also against the older brother's advice. Both Frank and his wife were atheists.
A Doctor of Philosophy is the highest university degree that is conferred after a course of study by universities in most English-speaking countries. PhDs are awarded for programs across the whole breadth of academic fields. As an earned research degree, those studying for a PhD are usually required to produce original research that expands the boundaries of knowledge, normally in the form of a thesis or dissertation, and defend their work against experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title Doctor or, in non-English-speaking countries, variants such as "Dr. phil." with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at universities or work in academic, educational, or research fields are usually addressed by this title "professionally and socially in a salutation or conversation." Alternatively, holders may use post-nominal letters such as "Ph.D.", "PhD", or "DPhil". It is, however, considered incorrect to use both the title and post-nominals at the same time.
The California Institute of Technology (Caltech) is a private doctorate-granting research university in Pasadena, California. Known for its strength in natural science and engineering, Caltech is often ranked as one of the world's top-ten universities.
Economics is the social science that studies the production, distribution, and consumption of goods and services.
Frank Oppenheimer received his PhD in 1939, and completed two postdoctoral years at Stanford.
During World War II, Frank's older brother Robert became the director of the Los Alamos Laboratory, part of the Manhattan Project, the Allied effort to produce the first atomic weapons. From 1941 to 1945 Frank worked at the University of California Radiation Laboratory on the problem of uranium isotope separation under the direction of his brother's good friend, Ernest O. Lawrence.In 1945 he was sent to the enrichment facility at Oak Ridge, Tennessee to help monitor the equipment. In late 1943 he arrived at the Los Alamos Laboratory. He worked directly under Kenneth T. Bainbridge. His responsibilities included the instrumentation for the Trinity test site, in New Mexico. Oppenheimer was involved in the founding of the Association of Los Alamos Scientists, on the 30th of August 1945. This organization promoted international peaceful control of nuclear power. He later also joined the Federation of American Scientists. He was also a member of the American Physical Society.
After the war, Oppenheimer returned to Berkeley, working with Luis Alvarez and Wolfgang Panofsky to develop the proton linear accelerator. In 1947 he took a position as Assistant Professor of Physics at the University of Minnesota,where he participated in the discovery of heavy cosmic ray nuclei.
On July 12, 1947, the Washington Times Herald reported that Oppenheimer had been a member of the Communist Party during the years 1937–1939. At first, he denied these reports, but later admitted they were true.In June 1949, as part of a larger investigation on the possible mishandling of "atomic secrets" during the war, he was called before the United States Congress House Un-American Activities Committee (HUAC). Before the Committee, he testified that he and his wife had been members of the Communist Party for about three and a half years. In 1937 they had been involved in local attempts to desegregate the Pasadena public swimming pool, which was open to non-whites only on Wednesday, after which the pool was drained and the water replaced.
Oppenheimer said he and his wife had joined at a time when they sought answers to the high unemployment experienced in the United States during the later part of the Great Depression. He refused to name others he knew to be members. This caused a media sensation—that J. Robert Oppenheimer's brother was an admitted former member of the Communist Party—and led to Frank resigning from his post at the University of Minnesota.
After being branded a Communist, Oppenheimer could no longer find work in physics in the US, and he was also denied a passport, preventing him from working abroad. 99 Frank and Jackie eventually sold one of the Van Gogh paintings he had inherited from his father, and with the money bought land in Pagosa Springs, Colorado, and spent nearly a decade as cattle farmers. :104–115:
In 1957, the Red Scare had lessened to the point that Oppenheimer was allowed to teach science at a local high school. Under Oppenheimer's tutelage, several students from Pagosa Springs High School took first prize at the Colorado State Science Fair. 117 Within two years, supported by endorsements from physicists Hans Bethe, George Gamow, and Victor Weisskopf, :130 Oppenheimer was offered a position at the University of Colorado teaching physics.:
While returning to particle physics research, Oppenheimer also took an increasing interest in developing improvements in science education. He was eventually awarded a grant from the National Science Foundation to develop new pedagogical methods, which resulted in a "Library of Experiments"—nearly one hundred models of classical laboratory experiments which could be used in aiding the teaching of physics to elementary and high school children. 138–139 These models would later become the core of the first exhibits at the Exploratorium. Oppenheimer also worked with the Physical Science Study Committee (PSSC), helping to develop a new high school physics curriculum in the immediate post-Sputnik years. :118:
In his work Oppenheimer followed the well-known old Latin principle Docendo discimus —"the best way to learn is to teach".

In 1965, Oppenheimer was awarded a Guggenheim Fellowship to study the history of physics and to conduct bubble chamber research at University College, London, where he was exposed to European science museums for the first time. 141 Inspired, Frank devoted the next years of his life to creating a similar resource in the United States. Upon his return from Europe, he was offered a job planning a new branch of the Smithsonian Institution in Washington, D.C., but he instead chose to work on setting up a completely independent new type of museum in San Francisco.:
Four years later, in 1969, the Exploratorium opened its doors for the first time—an interactive museum of art, science, and human perception based on the philosophy that science should be fun and accessible for people of all ages, set within the north wing of the stately Palace of Fine Arts of San Francisco. Oppenheimer was able to fund the opening of the Exploratorium partly due to a grant from the San Francisco Foundation. [ citation needed ] There were no admission charges at the Exploratorium for a full twelve years after its opening. The first exhibits in the Exploratorium were constructed with the aid of the Stanford Linear Accelerator Center (SLAC) and the Ames Research Center (NASA).The San Francisco Foundation gave a $50,000 grant to Oppenheimer to open the 90,000 square foot facility. Oppenheimer served as the first director of the museum, and was personally involved in almost every aspect of its daily operations for the rest of his life. Frank had also visited the Tel Aviv Science Museum in 1965 and later used several of Ivan Moscovich's designs and exhibits in his revolutionary Exploratorium in San Francisco.
Frank Oppenheimer had a lifelong belief in the importance of art in an equal and closely connected relationship to science. 185 He personally recruited artist Bob Miller to create Sun Painting, the first major art installation at the Exploratorium. :180 Another early work was the Tactile Dome (1971), by August Coppola (father of actor Nicolas Cage and brother of the film director Francis Coppola). This was a 3-dimensional tightly convoluted passage that was completely dark inside, and which visitors had to explore relying on the sense of touch, encountering many tactile experiences along the way. Both installations proved to be immensely popular, and renewed versions of both are still on display today. In 1974, Oppenheimer established an ongoing artist-in-residence program at the Exploratorium, regularly bringing in a succession of emerging and established artists working at the boundaries of art and science. :179–203:
The Exploratorium aimed to introduce and inspire, as well as teach. The museum exposed people to science by means of human perception. It provides a form of "educational sightseeing" as well as the understanding of the underlying principles. Its intention was not to replace a science class, but rather to inspire people to learn about science.The exhibits were arranged and structured to allow for free access to any part of the museum. Oppenheimer wanted people to be able to explore the museum and learn at their own pace, following a path that made sense to them and stimulated their curiosity. The idea of having people explore the museum in a way that appeals to everyone was an essential element. Instead of tour guides, fifteen to twenty college students or secondary students, as well as some adults, were employed as "explainers". They demonstrate the exhibits and explain the principles involved all while circulating among visitors, rather than guiding them along. Oppenheimer strove to make learning a fun and enjoyable experience for all.
In 1977, Oppenheimer was diagnosed with lymphoma, and underwent two years of successful chemotherapy. 294 Oppenheimer's first wife Jacquenette, died in 1980. In 1983, lung cancer was discovered (he was a heavy smoker ), and he underwent a lobectomy, in spite of which he continued to play the flute. :294 Oppenheimer still remained active, appearing at the Exploratorium nearly daily until the last few weeks of his life. He died at home in Sausalito, California, on February 3, 1985. :298:

Frank Oppenheimer died in 1985, leaving his second wife, Mildred Danielson, son Michael, and daughter Judith.
Oppenheimer's papers and archives were transferred to the Bancroft Library at the University of California, Berkeley. Oppenheimer authored over 60 technical and nontechnical papers.The bulk of this collection covers his work in physics and education in the years leading up to his founding of the Exploratorium. Also included are papers related to his investigation by the House Un-American Activities Committee (HUAC). Historical archives of the Exploratorium (1957—present) are also kept at the Bancroft. The University of Minnesota holds archives covering Oppenheimer's physics work during 1946-1959.
Oppenheimer considered the Exploratorium and its educational programs to be his most important accomplishment and legacy. A collection of selected Oppenheimer papers on science, art, and education is available online at the Exploratorium website.
The Frank Oppenheimer Fellowship Fund was created at the Exploratorium to provide for the exchange of science museum personnel both nationally and internationally.
Interviewed by director Jon Else, Frank Oppenheimer appears throughout The Day After Trinity (1980), an Academy Award-nominated documentary about J. Robert Oppenheimer and the building of the atomic bomb.

Physics outreach encompasses facets of science outreach and physics education and is an umbrella term for a variety of activities by schools, research institutes, universities, clubs and institutions such as science museums aimed at broadening the audience for and awareness and understanding of physics. While the general public may sometimes be the focus of such activities, physics outreach often centers on developing and providing resources and making presentations to students, educators in other disciplines, and in some cases researchers within different areas of physics.
For the locals, it was as if aliens had landed. "The normal folks were wearing tight jeans and cowboy hats, and here was a rancher who didn't wear a hat," said Pete Richards, who lived on one of the neighboring ranches at the time. "He was skinnier than a rail, he was really hyper. Both he and Jackie swore like sailors. And they were atheists!.
