Inge Lehmann, (born May 13, 1888, Copenhagen, Denmark—died February 21, 1993, Copenhagen), Danish seismologist best known for her discovery of the inner core of Earth in 1936 by using seismic wave data.

Lived 1888 - 1993. Inge Lehmann overturned the idea that our planet's metallic core is entirely molten liquid. She used mathematics to analyze the way energy released by earthquakes travels through the earth. She discovered something eternally concealed from the naked eye - thousands of miles below our feet, at its center, the earth is solid.

Lehmann is first and foremost known as the discoverer of Earth's inner core in 1936, but she is also highly regarded for her studies of Earth's mantle, carried out during many visits to the United States in the 1950s and the 1960s.

Inge Lehmann was born in Copenhagen, Denmark in 1888 to an intellectual family 2 (p.287). She received her early education at Hannah Adler's progressive high school, which promoted equal treatment of boys and girls 2 (p.287). Early on, her mathematics teacher noticed her talent for the subject and encouraged her to take on extra tasks 2 (p. 287).

Inge Lehmann was a popular Danish seismologist and geophysicist who made revolutionary discovery in the field of seismology and geophysics. She was the first to thwart the age-old conception of the Earth's inner core being molten. Through her research, she clearly explained that the Earth's core was solid but surrounded by a molten outer core.

Inge Lehmann (født 13. maj 1888 i København, død 21. februar 1993 sammesteds) var en dansk seismolog og statsgeodæt. Hun fik i 1920 kandidatgraden i matematik fra Københavns Universitet . Liv og gerning Hun blev født i Danmark i 1888 som datter af professor Alfred Georg Ludvig Lehmann (1858-1921) og Ida Sophie Tørsleff (1866-1935).

Inge Lehmann was a Danish seismologist and geophysicist who analysed how energy released from earthquakes travels through the Earth. Through her findings, she was able to discover the Earth's core is composed of two parts: a solid metal core surrounded by an outer liquid core.

Inge Lehmann, Danish Seismologist. Danish Seismologist Inge Lehmann was born into a family of movers and shakers. She was raised at Osterbro, by the Lakes in Copenhagen and attended a non-traditional school that practiced gender equity. Her sister, Harriet, and she carried a legacy of influence and intellect brought from ancestral roots in ...

May 13, 2019 Inge Lehmann, a Danish seismologist, was born May 13, 1888. In the early 1930s, Lehmann was studying seismic waves that were being reflected from various layers within the earth, and she observed that there were certain reflections that could not be explained by the known internal structure of the earth.

Between 1929 and 1939, seismologist Inge Lehmann compared various data sets from earthquakes to conclusively prove what was at the Earth's core. On 17 June 1929, at around 10:17 local time, a 7.3-magnitude earthquake struck the South Island of New Zealand.

Inge Lehmann was a prominent Danish seismologist and geophysicist, who made a ground-breaking discovery about the structure of the Earth's core. Trained in Mathematics at the universities of Copenhagen and Cambridge, Lehmann analysed how energy released from earthquakes travels through the Earth.

At the age of 105, Inge Lehmann (1888-1993) looked back on a long, productive life with satisfaction. During her career in seismology, she had made two major discoveries and made other significant ...

Inge Lehmann (1888-1993) er Danmarks ukendte pioner inden for geofysik. I 1936 skriver hun artiklen P', hvor hun argumenterer for, at Jorden har en fast indre kerne. Den tanke skaber stor debat i videnskabskredse, men det skal snart vise sig, at hun har ret. Alligevel kommer der til at gå mange år, inden hun får sin velfortjente anerkendelse.

Inge Lehmann is an exceptionally gifted and inquisitive person and even as a child she had a proclivity towards knowledge, which her parents also had to acknowledge when they discover the 11-year-old Inge with some older boys after a school ball - hard at work solving quadratic equations.

The Inge Lehmann Medal is given annually to a senior scientist in recognition of outstanding contributions to the understanding of the structure, composition, and dynamics of the Earth's mantle and core.

Leben. Inge Lehmann wurde als Tochter des Experimentalpsychologen Alfred Lehmann und dessen Frau Ida Sophie Tørsleff (1866-1935) im Kopenhagener Stadtteil Østerbro geboren, wo sie auch aufwuchs. Ihre Familie war eine alteingesessene Kopenhagener Familie, zu der auch der Jurist und Politiker Orla Lehmann gehörte.. Ihre Schulausbildung erhielt sie an einer pädagogisch fortschrittlichen ...

Inge Lehmann discovered that the Earth's inner core is solid surrounded by a molten outer core. Her interest in parts of the Earth started when she would read cardboard cards with information regarding earthquakes in different parts of the world. She studied shock waves and theorized that waves travelled a distance into the central core and ...

In 1936, the Danish seismologist Inge Lehmann(1888-1993), who worked for the Danish GeodeticInstitute from 1925 to 1952, suggested from the analysisof P-wave data that the Earth must have an inner core—an important breakthrough in the understanding ofthe nature of the Earth's interior. Inge Lehmann (1888-1993)

Inge Lehmann was a Danish seismologist-a physicist who studied waves in the Earth's crust-active in the mid-20th century. She is most remembered for her theory of the Earth's solid inner core, based on her work on seismic waves caused by earthquakes. Inge Lehmann was born in Copenhagen, Denmark on May 13, 1888.
