Kai Manne Börje Siegbahn was born on April 20, 1918, and died on July 20, 2007. He was a Swedish physicist who won the 1981 Nobel Prize in Physics along with others.
Arne Wilhelm Kaurin Tiselius was born on August 10, 1902, and died on October 29, 1971. He was a Swedish scientist who studied living things and won the Nobel Prize in Chemistry in 1948. He received the prize for his work on methods to separate and study proteins, particularly for his discoveries about the different parts that make up serum proteins.
Theodor Svedberg (30 August 1884 – 25 February 1971) was a Swedish chemist who won the Nobel Prize for his research on colloids and proteins using an ultracentrifuge. Svedberg worked at Uppsala University from the mid-1900s until the late 1940s. At Uppsala, he began as a docent and later became the head of the university’s physical chemistry department in 1912.
Georg von Békésy (Hungarian: Békésy György, pronounced [ˈbeːkeːʃi ˈɟørɟ]; 3 June 1899 – 13 June 1972) was a Hungarian-American scientist who studied biology and physics. Using strobe photography and silver flakes as markers, he discovered that the basilar membrane moves in a wave-like pattern when sound waves stimulate it. The shape of the cochlea and the structure of the basilar membrane cause different sound frequencies to create the largest vibrations in different areas along the cochlea.
Rune Elmqvist was born on December 1, 1906, and died on December 15, 1996. He was a Swedish doctor who later became an engineer. He helped create the first implantable pacemaker in 1958.
Carl-Gustaf Arvid Rossby (born December 28, 1898, and died August 19, 1957) was a scientist who studied weather and was born in Sweden but worked in the United States. He was the first to explain how the atmosphere moves on a large scale using the study of how liquids and gases move. He discovered and described the jet stream and the long waves in the westerly winds, which are now called Rossby waves.
Hannes Olof Gösta Alfvén was a Swedish electrical engineer and plasma physicist who won the 1970 Nobel Prize in Physics for his research on magnetohydrodynamics (MHD). He discovered a type of MHD wave that is now called Alfvén waves. He first studied electrical power engineering and later worked in research and teaching related to plasma physics and electrical engineering.
Knut Emil Lundmark (born 14 June 1889 in Älvsbyn, Sweden; died 23 April 1958 in Lund, Sweden) was a Swedish astronomer, a professor of astronomy, and the head of the observatory at Lund University from 1929 to 1955. Lundmark studied astronomy at the Uppsala University Observatory. His dissertation, completed in 1920, was titled The relations of the globular clusters and spiral nebulae to the stellar system.
Anders Jonas Ångström (pronounced /ˈæŋstrəm/; Swedish: [ˈânːdɛʂ ˈjûːnas ˈɔ̂ŋːstrœm]; August 13, 1814 – June 21, 1874) was a Swedish scientist who helped create the field of spectroscopy, which studies how light interacts with matter. Ångström is also known for his research on astrophysics, how heat moves, Earth’s magnetic field, and the northern lights. In 1852, he wrote a book called Optiska undersökningar (Optical investigations), where he described a rule about how light is absorbed.
Lasse Leif Hessel (9 September 1940 – 25 April 2019), also called “the family doctor,” was a Danish inventor, author, and Doctor of Medicine. He is known for creating the Femidom and the Femi-X pill. He was a well-known expert internationally on nutrition and dietary fibre.
