Arnold O. Beckman

Arnold O. Beckman was an influential American chemist and inventor, best known for his contributions to analytical chemistry. He created the first commercially available pH meter in the 1930s, revolutionizing how scientists measured acidity and alkalinity in various solutions. This invention greatly enhanced laboratory precision and efficiency. Beckman also founded Beckman Instruments, a company that developed advanced scientific equipment, including spectrophotometers, which analyze the absorption of light by substances. His work has significantly impacted fields ranging from biology to environmental science, making complex measurements more accessible for researchers and improving experimental accuracy.
