Nobel Laureates

Caltech has 39 Nobel laureates among its alumni and faculty, 19 of whom are alumni only. Some of the most prominent Nobel laureates who graduated from Caltech are:

  • Richard Feynman: He was a theoretical physicist who received the Nobel Prize in Physics in 1965 for his work on quantum electrodynamics. He was also known for his lectures, books, and eccentric personality.
  • Linus Pauling: He was a chemist and biochemist who received two Nobel Prizes: one in Chemistry in 1954 for his research on chemical bonds and molecular structure, and one in Peace in 1962 for his activism against nuclear weapons. He was also a pioneer in the fields of molecular biology and orthomolecular medicine.
  • Kip Thorne: He is a theoretical physicist who received the Nobel Prize in Physics in 2017 for his contributions to the detection of gravitational waves. He is also a co-founder of the Laser Interferometer Gravitational-Wave Observatory (LIGO) and an executive producer of the film Interstellar.
  • Andrea Ghez: She is an astronomer who received the Nobel Prize in Physics in 2020 for her discovery of a supermassive black hole at the center of our galaxy. She is also a professor at UCLA and a recipient of the MacArthur Fellowship.

Entrepreneurs and Business Leaders

Caltech has also produced many successful entrepreneurs and business leaders who have founded or led influential companies and organizations. Some of them are:

  • Charlie Munger: He is a billionaire investor and vice chairman of Berkshire Hathaway, the conglomerate led by Warren Buffett. He is also a philanthropist who has donated millions of dollars to Caltech and other institutions.
  • Gordon Moore: He is a co-founder of Intel Corporation, the world’s largest semiconductor company. He is also known for Moore’s law, which predicts the exponential growth of computing power over time.
  • Frank Capra: He was a film director and producer who won three Academy Awards for Best Director for his movies It Happened One Night, Mr. Deeds Goes to Town, and You Can’t Take It with You. He also directed the classic films It’s a Wonderful Life and Mr. Smith Goes to Washington.
  • David Ho: He is a physician and virologist who pioneered the development of antiretroviral therapy for HIV/AIDS. He was named Time magazine’s Person of the Year in 1996 for his breakthroughs in AIDS research.

Scientists and Inventors

Caltech has also been home to many brilliant scientists and inventors who have advanced human knowledge and technology in various domains. Some of them are: California Institute of Technology

  • Donald Knuth: He is a computer scientist and mathematician who is widely regarded as the father of algorithm analysis and computer typesetting. He is also the author of The Art of Computer Programming, one of the most influential books in computer science.
  • Benoit Mandelbrot: He was a mathematician and polymath who coined the term fractal and developed the theory of fractal geometry. He also applied his ideas to various fields such as physics, biology, finance, art, and music.
  • Howard Hughes: He was an aviator, engineer, filmmaker, and philanthropist who set several world records for flying speed and distance. He also produced several movies such as Hell’s Angels, Scarface, and The Outlaw. He was also known for his eccentricity and reclusiveness.
  • Edward Fredkin: He is a physicist and computer scientist who proposed the digital physics hypothesis, which suggests that the universe is essentially a giant computer simulation. He also invented the trie data structure, the Fredkin gate, and the Billiard-Ball Computer Model.
