Kronenberg (1921 2008) was a German-born and -educated physicist who specialised in magnetism. After immigrating to the United States, Kronenberg worked from 1953 to 1963 at the Indiana General Corporation, Magnetics Division, in Valparaiso, Indiana, then as an associate professor at California State Polytechnic University in Pomona, California. In 1985, Kronenberg reported anecdotal evidence for the pseudoscientific theory that magnetic water treatment could have a memory effect on water, preventing the formation of scale even after the magnetic field was removed.
