Mikkel Frandsen (1892–1981) was a Danish American physical chemist noted for experiments involving chemical thermodynamics, oil, and heavy water. Also known as deuterium oxide (D2O), heavy water is used to produce nuclear power and is used in other nuclear applications such as nuclear magnetic resonance spectroscopy. ==Early years== Frandsen was born in Sønder Lem Sogn in the town of Ringkøbing in Ringkøbing-Skjern municipality in Region Midtjylland in Denmark. He emigrated from Denmark to the United States in 1921. Frandsen earned his Ph.D. in Physical Chemistry from the University of California in 1926. In 1928, Frandsen invented the Liquid Phase Cracking Process, discovering that when oil is heated to a point at which cracking (chemistry) takes place, the heat consumed causes the oil temperature to decrease. This results in an increased yield of gasoline and a decreased knocking tendency of gasoline.
