|Heinrich Hertz (1857-1894)|
At least four members of the Hertz family are noteworthy scientists:
1. Heinrich Rudolf Hertz (1857-1894) founded the science of contact mechanics in 1882, discovered the photoelectric effect in 1887 and demonstrated the existence of electromagnetic waves in 1888. The SI unit of frequency (symbol Hz) was formally named after him, in 1960 (it had been introduced in 1930 to replace the former cps = cycle per second).
2. Gustav Ludwig Hertz (1887-1975). Nobel 1925. Nephew of Heinrich.
3. Hellmuth Hertz (1920-1990). Pioneer of medical ultrasonography. Son of Gustav.
4. Hans Hertz (born on 1955-08-22 in Lund, Sweden). Son of Hellmuth and grandson of Gustav. Hans Martin Hertz was elected ro the Royal Swedish Academy of Sciences in 2007 and to the Royal Swedish Academy of Engineering Sciences in 2008.
