Arnold Orville Beckman (April 10, 1900 – May 18, 2004) was an American chemist, inventor, investor, and philanthropist. While a professor at California Institute of Technology, he founded Beckman Instruments based on his 1934 invention of the pH meter, a device for measuring acidity (and alkalinity), later considered to have "revolutionized the study of chemistry and biology".[1] He also developed the DU spectrophotometer, "probably the most important instrument ever developed towards the advancement of bioscience".[2] Beckman funded the Shockley Semiconductor Laboratory, the first silicon transistor company in California, thus giving rise to Silicon Valley.[3] After retirement, he and his wife Mabel (1900–1989) were numbered among the top philanthropists in the United States.[4]
