Modern-day cleanroom invented by Sandia physicist still used 50 years later

Cleanroom inventor Willis Whitfield

When retired Sandia National Laboratories physicist Willis Whitfield invented the modern-day cleanroom 50 years ago, researchers and industrialists didn’t believe it at first. But within a few short years, $50 billion worth of laminar-flow cleanrooms were being built worldwide and the invention is used in hospitals, laboratories and manufacturing plants today.

Whitfield was dubbed “Mr. Clean” by TIME Magazine at the time, but the travel, scientific presentations and accolades didn’t change the unassuming scientist, who was always modest about the invention that revolutionized manufacturing in electronics and pharmaceuticals, made hospital operating rooms safer and helped further space exploration.
