Burton Richter was a highly influential American physicist. He dedicated his career to studying the fundamental building blocks of the universe. His work focused on elementary particle physics. This field examines the smallest known components of matter. Richter is most famous for discovering a new subatomic particle. This discovery fundamentally changed our understanding of how matter is organized. His research helped spark a period known as the November Revolution in particle physics.

To study these tiny particles, Richter needed incredibly powerful tools. He collaborated with a Stanford professor named David Ritson to design a new machine. This machine was called the Stanford Positron-Electron Asymmetric Ring, or SPEAR. SPEAR was a type of particle accelerator. It used a ring to move particles at extremely high speeds. Richter led the construction of SPEAR with support from the U.S. Atomic Energy Commission. The machine allowed scientists to observe the results of particle collisions.

The discovery process involved colliding particles within the SPEAR accelerator. By smashing these particles together, the team could see what new things were created. In 1974, Richter's team identified a new subatomic particle. Richter gave this particle the name psi. At the exact same time, a different team made the same discovery. This second team was led by Samuel Ting at Brookhaven National Laboratory. Ting called the particle J. Because of these two separate groups, the particle is called the J/psi meson.

Richter's academic journey began in New York City. He was born on March 22, 1931, in Brooklyn. He grew up in the Far Rockaway neighborhood of Queens. His father, Abraham Richter, worked in the textile industry. Richter attended Far Rockaway High School. He later moved to Pennsylvania to attend Mercersburg Academy. He then went to the Massachusetts Institute of Technology. He earned his bachelor's degree in 1952. He completed his PhD in 1956.

His professional achievements earned him many prestigious honors. For his work on the J/psi meson, Richter and Ting won the Nobel Prize in Physics in 1976. This is one of the highest honors in science. He also served as the director of the Stanford Linear Accelerator Center from 1984 to 1999. In 2012, President Barack Obama announced he had received the Enrico Fermi Award. In 2014, he was awarded the National Medal of Science. These awards recognized his contributions to electron accelerators and particle physics.

Beyond the laboratory, Richter was an active voice in science policy. He served on the JASON advisory group. He also worked with an organization called Scientists and Engineers for America. This group promotes sound science within the American government. In 2008, he was one of 20 American Nobel laureates to sign a letter to President George W. Bush. The letter urged the president to provide more funding for science research. He wanted to protect the work done by the Department of Energy and the National Science Foundation.

Richter's impact reached into many different areas of study. He was a professor at Stanford University for many years. He also held the title of Paul Pigott Professor in the Physical Sciences Emeritus. His work with accelerators helped develop synchrotron light sources. These are tools used in many different types of scientific research. He even shared his views on energy policy and nuclear power. Richter passed away on July 18, 2018, in Stanford, California. He was 87 years old.
