Martin Kamen

Martin Kamen, born on August 27, 1913, was a pioneering American physicist and chemist whose groundbreaking work significantly advanced the fields of biochemistry and molecular biology. He is best known for his collaboration with Sam Ruben, with whom he co-discovered the synthesis of the isotope carbon-14 on February 27, 1940, at the University of California Radiation Laboratory in Berkeley.

In 1941, Kamen made another remarkable contribution to science by confirming that all of the oxygen released during photosynthesis originates from water rather than carbon dioxide. This discovery not only deepened the understanding of photosynthesis but also laid the groundwork for future research in plant biology.

Kamen was the first scientist to utilize carbon-14 to investigate biochemical systems, a revolutionary approach that allowed researchers to trace a wide array of biological reactions and processes. His innovative techniques opened new avenues in scientific research, transforming the landscape of biochemistry.

Despite facing significant challenges, including being blacklisted for nearly a decade due to suspicions of being a security risk, Kamen's contributions did not go unrecognized. He was honored with the Albert Einstein World Award of Science in 1989 and received the prestigious Enrico Fermi Award from the U.S. Department of Energy in 1995 for his lifetime achievements in science.
