The Einstein Tower (German: Einsteinturm ) is an astrophysical observatory in the Albert Einstein Science Park in Potsdam , Germany built by architect Erich Mendelsohn . It was built on the summit of the Potsdam Telegraphenberg to house a solar telescope designed by the astronomer Erwin Finlay-Freundlich . The telescope supports experiments and observations to validate (or disprove) Albert Einstein 's relativity theory . The building was first conceived around 1917, built from 1919 to 1921 after a fund-raising drive, and became operational in 1924. Although Einstein never worked there, he supported the construction and operation of the telescope. It is still a working solar observatory today as part of the Leibniz Institute for Astrophysics Potsdam . Light from the telescope is directed down through the shaft to the basement where the instruments and laboratory are located. There were more than half a dozen telescopes in the laboratory.
43-421: This was one of Mendelsohn's first major projects, completed when a young Richard Neutra was on his staff, and is his best-known building. Between 1917 and 1920 Mendelsohn created numerous sketches with the attempt to create a structure that reflects Einstein's groundbreaking theories. The exterior was originally conceived in concrete, but due to construction difficulties with the complex design and shortages from

In the Sun's photosphere, the most ubiquitous phenomenon are granules — convection cells of plasma each approximately 1,000 km (620 mi) in diameter with hot rising plasma in the center and cooler plasma falling in the spaces between them, flowing at velocities of 7 km/s (4.3 mi/s). Each granule has
129-487: A 1947 article for the Los Angeles Times , "The Changing House," Neutra emphasizes the "ready-for-anything" plan – stressing an open, multifunctional plan for living spaces that are flexible, adaptable and easily modified for any type of life or event. Neutra had a sharp sense of irony. In his autobiography, Life and Shape , he included a playful anecdote about an anonymous movie producer-client who electrified
172-515: A long tour of the completed structure, waiting for some sign of approval. The design, while logical and perfectly sufficient to its purpose, stood out like an "ungainly spaceship" in the suburbs of Potsdam. Einstein said nothing until hours later, during a meeting with the building committee, when he whispered his one-word judgment: "Organic". Mendelsohn himself said that he had designed it out of some unknown urge, letting it emerge from "the mystique around Einstein's universe". In 1911 Einstein published
215-672: A partnership with his son Dion Neutra. Between 1960 and 1970, Neutra created eight villas in Europe, four in Switzerland, three in Germany, and one in France. Prominent clients in this period included Gerd Bucerius , publisher of Die Zeit , as well as figures from commerce and science. His work was also part of the architecture event in the art competition at the 1932 Summer Olympics . Richard Joseph Neutra died on April 16, 1970, at
258-585: A physician and environmental epidemiologist. Richard Neutra moved to the United States by 1923 and became a naturalized citizen in 1929. He worked briefly for Frank Lloyd Wright before accepting an invitation from Rudolf Schindler , a close friend from his university days, to work and live communally in Schindler's Kings Road House in California. Neutra's first works in California were both in

Neutra was born in Leopoldstadt, the second district of Vienna , Austria Hungary , on April 8, 1892, into a wealthy Jewish family. His Jewish-Hungarian father Samuel Neutra (1844–1920), was a proprietor of a metal foundry, and his mother, Elizabeth "Betty" Glaser Neutra (1851–1905)
344-528: A single stone (German: 'ein Stein') was placed where the bust had stood, a tradition that is still kept (the stone is regularly stolen or moved and has to be replaced). A few meters in front of the stairs to the Einstein Tower and set into the pavement of the forecourt is a fist-sized art object, a bronze reproduction of a human brain highly reduced in size, its shiny surface a sign of wear, inscribed with

Taking up this idea, März titled his work "the 3 SEC Bronze Brain – Admonition to the Now – Monument to the continuous present" (translation). With the newest refurbishment of the Einstein Tower, a sign in front was unveiled with an access to
430-1142: A visiting professor of design at Bennington College in Bennington, Vermont. In 1949 Neutra formed a partnership with Robert E. Alexander that lasted until 1958, which finally gave him the opportunity to design larger commercial and institutional buildings. In 1955, the United States Department of State commissioned Neutra to design a new embassy in Karachi. Neutra's appointment was part of an ambitious program of architectural commissions to renowned architects, which included embassies by Walter Gropius in Athens, Edward Durrell Stone in New Delhi, Marcel Breuer in The Hague, Josep Lluis Sert in Baghdad, and Eero Saarinen in London. In 1965, Neutra formed

Pictures of Einstein were removed and sculptures were supposedly melted down. However, after 1945 it was discovered that staff members had rescued the portrait bust now to be seen at the base of the tower by hiding it behind crates in the spectrograph lab. As a hidden homage to Einstein
817-628: The Neutra-designed Kronish House (1954) at 9439 Sunset Boulevard in Beverly Hills sold for $ 12.8 million. In 2009, the exhibition "Richard Neutra, Architect: Sketches and Drawings" at the Los Angeles Central Library featured a selection of Neutra's travel sketches, figure drawings and building renderings. An exhibition on the architect's work in Europe between 1960 and 1979 was mounted by
860-589: The San Fernando Valley (now destroyed). A photo of Neutra and Rand at the home was taken by Julius Shulman . Neutra's early watercolors and drawings, most of them of places he traveled (particularly his trips to the Balkans in WWI) and portrait sketches, showed influence from artists such as Gustav Klimt , Egon Schiele etc. Neutra's sister Josefine, who could draw, is cited as developing Neutra's inclination towards drawing. Neutra's son Dion has kept

The characteristics and behavior of magnetic fields provide the key to understanding solar activity and are at the focus of work at the Einstein Tower. The solar magnetic field can be measured with the help of a double spectrograph and two photoelectric polarization analyzers. Measurements in the photosphere , the visible light realm, permit conclusions about
1075-548: The digital exhibition Einsteinturm revisited . The exhibition shows how the Einstein Tower was conceived both scientifically and architecturally, and explains, why it needs to be refurbished on a regular basis. Richard Neutra Richard Joseph Neutra ( / ˈ n ɔɪ t r ə / NOI -tra ; April 8, 1892 – April 16, 1970) was an Austrian-American architect . Living and building for most of his career in Southern California , he came to be considered
1118-597: The early 1930s, Neutra's Los Angeles practice trained several young architects who went on to independent success, including Gregory Ain , Harwell Hamilton Harris , and Raphael Soriano . In 1932, he tried to move to the Soviet Union, to help design workers' housing that could be easily constructed, as a means of helping with the housing shortage. In 1932, Neutra was included in the seminal MoMA exhibition on modern architecture, curated by Philip Johnson and Henry-Russell Hitchcock . From 1943 to 1944, Neutra served as
1161-410: The elongated profile of the entire facility. Soon after research started at the site, it became evident that the proof sought would be harder to obtain than originally anticipated since the minimal shift of spectral lines was obscured by other solar influences. The reason was atmospheric turbulence on the solar surface. However, Einstein and Freundlich had from the beginning not only been interested in
1204-603: The four characters, 3 SEC. It was created by the Berlin artist Volker März , who placed it here and in an identical form in front of the Neurological Institute of the Charité in Berlin. The small sculpture refers to a scientific thesis of Ernst Pöppel according to which "the experience of continuity is based on an illusion. Continuity arises through the networking of contents, which in each case are represented in
1247-458: The initial version of his innovative General Theory of Relativity. One of the predicted effects according to the theory was a slight shift of spectral lines in the sun's gravitation field, now known as the red shift . The solar observatory in Potsdam was designed and constructed primarily to verify this phenomenon. The Mount Wilson Observatory in California, the first tower telescope worldwide,
1290-408: The lab rooms are under each other; in Potsdam they are arranged horizontally. Another rotating mirror directs the sunlight to the spectrograph lab located in the basement behind an earthen wall on the southern side of the tower. It is about 14 m long and thermally insulated. Here is where the light is split up into its spectral components and analyzed. This design of a horizontal laboratory wing led to
1333-698: The landscape architect Gustav Ammann . In 1921, he served briefly as city architect in the German town of Luckenwalde , and later in the same year he joined the office of Erich Mendelsohn in Berlin. Neutra contributed to the firm's competition entry for a new commercial center for Haifa, Palestine (1922), and to the Zehlendorf housing project in Berlin (1923). He married Dione Niedermann, the daughter of an architect, in 1922. They had three sons, Frank L (1924–2008), Dion (1926–2019), who became an architect and his father's partner, and Raymond Richard Neutra (1939–),

This was a much-embellished account of an actual client, Josef von Sternberg , who indeed had a moated house but not an electrified one. The novelist/philosopher Ayn Rand was the second owner of the Von Sternberg House in
1419-462: The photosphere is typically used to describe the Sun 's or another star 's visual surface. The term photosphere is derived from Ancient Greek roots, φῶς, φωτός/ phos , photos meaning "light" and σφαῖρα/ sphaira meaning "sphere", in reference to it being a spherical surface that is perceived to emit light. The surface of a star is defined to have a temperature given by the effective temperature in
