Carl Hellmuth Hertz

Carl Hellmuth Hertz (also written Carl Helmut Hertz, 15 October 1920 – 29 April 1990) was the son of Gustav Ludwig Hertz and great nephew of Heinrich Hertz.

Hellmuth Hertz was born October 15, 1920 in Berlin, Germany. His father was Gustav Hertz who, along with James Franck, was awarded the Nobel Prize in Physics 1925 for their experiments on inelastic electron collisions in gases. Gustav Hertz's uncle was in turn Heinrich Hertz, who who first conclusively proved the existence of the electromagnetic waves.

Hellmuth graduated from the elite Schule Schloss Salem boarding school in 1939 at the age of 19 years with the highest grade in mathematics and physics. The same year, he was conscripted into the German Army (Wehrmacht) and served as a soldier for Nazi Germany in World War II. In 1943 he was captured in the North African theatre (World War II) by US troops and brought to America where he was placed in a prisoner-of-war camp until 1946. Afterwards, James Franck and the Nobel laureate Niels Bohr, who was a friend of Gustav Hertz, helped Hellmuth get a job in Lund, Sweden.

From 1961 he was a teacher at Lund University, and from 1963 he was Professor of Electrical Measurement Technology in Lund, where he was involved in the development of both the inkjet and the ultrasound technology. For instance, together with the Swedish physician Inge Edler he produced the first echocardiographs. He was married to Birgit Nordbring and father of Thomas and Hans Hertz, and he died April 29, 1990.
