Francis Harry Compton Crick was a British molecular biologist, biophysicist and neuroscientist. He won the Nobel Prize in Physiology and Medicine in 1962.
During World War II he had to work on developments for the military, and in 1947 he turned to biology at the Strangeways Research Laboratory, University of Cambridge. In 1949 he moved to the University Medical Research Council at Cavendish Laboratories. Using X-ray diffraction studies of DNA by biophysicist Maurice Wilkins (1916-2004) and X-ray diffraction images taken by Rosalind Franklin, biophysicist James Watson and Crick were able to construct a molecular model consistent with the known physical and chemical properties of DNA.
This achievement became a cornerstone of genetics and was regarded as one of the most important discoveries of 20th century biology. In 1962, Francis Crick, along with James Watson and Maurice Wilkins, won the Nobel Prize in Physiology or Medicine for determining the molecular structure of deoxyribonucleic acid (DNA), the chemical ultimately responsible for the hereditary control of life functions.
From 1977 until the end of his life, Crick served as professor emeritus at the Salk Institute for Biological Studies in San Diego, California, where he conducted research on the neurological basis of consciousness. He also wrote several books. In 1991, Francis Crick received the Order of Merit.
Karlheinz Stockhausen was a German innovative and avant-garde composer, conductor, and musical theorist.
Stockhausen studied at the State Academy of Music in Cologne and the University of Cologne, then in 1952 in Paris with composers Olivier Messiaen and Darius Millau. Returning to Cologne in 1953, he joined the electronic music studio West German Broadcasting (Westdeutscher Rundfunk), of which he was artistic director from 1963 to 1977. Stockhausen created his first electronic music piece in 1953.
In the mid-1950s Stockhausen studied phonetics, acoustics and information theory at the University of Bonn, all of which he used in his musical compositions. From 1953 he began teaching composition in Darmstadt and later organized seminars in Cologne. From 1971 to 1977 he was already professor of composition at the State Academy of Music in Cologne.
Stockhausen used both electronic and traditional instrumentation and supported his approach with rigorous theoretical reasoning and radical innovations in musical notation. He ensured that sounds were equally interesting regardless of the order in which they appeared; random decisions of musical order play an important role in many of his compositions.
Stockhausen lectured and gave concerts with his works throughout Europe and North America. As a creator and theorist of electronic and serial music, he had a significant influence on avant-garde composers of the 1950s and 1980s.
Heinrich Rudolf Hertz was a German physicist and inventor of radio waves.
Hertz graduated from the University of Berlin, studying under Hermann von Helmholtz and Gustav Kirchhoff, then was a professor of physics at the University of Karlsruhe, and from 1889 became a professor of physics at the University of Bonn.
A tireless experimenter, Hertz conducted various experiments with electric waves. Hertz reported his first discovery at the end of 1887 in a treatise "On the electromagnetic effects caused by electrical perturbations in insulators," which he sent to the Berlin Academy. For a time the waves he discovered were called Hertzian waves, but today they are known as radio waves. Hertz's discovery was a confirmation of James Clerk Maxwell's electromagnetic theory and paved the way for numerous advances in communication technology.
Hertz is also known for the discovery of the photoelectric effect, which occurred during his research on electromagnetic waves. Hertz was only 37 years old at the time of his death and many of his experiments and work remained unfinished, but his discovery of radio waves had a huge impact on the world in the 20th century, paving the way for the development of radio, television and radar.
