Astrophysicist and former MIT physics professor Walter Lewin hails from the Netherlands. Lewin was born to Walter Simon Lewin and Pieternella Johanna van der Tang in The Hague, Netherlands, in 1936. He was a kid during World War II when the Nazis invaded the Netherlands. His Jewish paternal grandparents, Gustav and Emma Lewin, perished in Auschwitz in 1942, probably through typhus and hunger. Lewin’s father disappeared without a trace, presumably to keep his family safe, leaving Lewin’s mother to raise the twins alone.

As an avid collector and dealer, Lewin has a passion for art. He has lectured about it at the Massachusetts Institute of Technology. In the 1970s and 1980s, he collaborated with digital artist Peter Struycken and German-born, ZERO movement pioneer and director of MIT’s Center for Advanced Visual Studies Otto Piene.

While earning his doctorate, Walter Lewin taught high school physics. In January 1966, he became a postdoctoral associate at the Massachusetts Institute of Technology and was later promoted to assistant professor. He began as an assistant professor of physics in 1968 and eventually became a full professor in 1974.


Lewin collaborated with George W. Clark on all-sky balloon surveys after joining the MIT X-ray astronomy project. From the 1970s until the 1980s, around twenty balloon flights were completed without incident. Five more X-ray sources, with quite different spectra from the ones detected in rocket observations, were uncovered thanks to these balloon surveys. The X-ray radiation from these sources was highly variable. One of these was GX 1+4, which had an X-ray flux that appeared to be periodic at a rate of around once every 2.4 minutes. This discovery was the first-ever detection of a neutron star with a sluggish rotation rate.

After the discovery of Scorpius X-1 in October 1967, an X-ray flare was seen. The flux quadrupled in about five minutes before leveling off. For the first time in the experiment series, X-ray variability was seen. Since the rockets used by other researchers were only in the air for a few minutes, they may not have been able to detect the X-ray source variability over such short intervals of time, while the balloons could remain aloft for several hours.

A co-investigator on the Small Astronomy Satellite 3 (SAS-3) project, Lewin’s name is well-known in the field. He oversaw the burst observations and discovered other X-ray bursters, including the fast burster, which can emit thousands of X-ray bursts each day. A study by his group discovered that the quick burster produces two distinct types of explosions, which they labeled type I (thermonuclear flashes) and type II (thermonuclear flashes) (accretion flow instabilities).

Lewin contributed as a co-principal investigator on the HEAO-1 (A4) High Energy Astronomy Observatory, which compiled the first all-sky catalog of high-energy X-rays. Using the Danish observatory SAS-3 and the Japanese observatory Hakucho, Lewin, and his colleagues H. Pedersen and J. van Paradijs conducted in-depth research on optical bursts in conjunction with X-ray bursts. The cumulative burst times of the X-ray and optical observations show that the optical bursts occur a few seconds after the X-ray bursts. As a result, scientists were able to calculate the width of the accretion disc that forms around neutron stars during their accretion process.

While working with colleagues in Amsterdam and Garching, Germany, Lewin conducted guest observations with the European observatory EXOSAT in 1984 and 1985 to look for millisecond X-ray pulsations from low-mass X-ray binaries. An unexpected finding of intensity-dependent quasi-periodic oscillations in the X-ray emission of GX 5-1. (QPO). Using the Japanese observatory “Ginga,” Lewin and his team studied the correlation between the X-ray spectral condition and the radio brightness of numerous strong low-mass X-ray binaries from 1989 to 1992.

Lewin and his graduate student, David Pooley, conducted considerable research into the origins of supernovae and weak X-rays in globular clusters. This work was a joint effort by researchers from the University of Washington, Princeton’s Institute for Advanced Study, the University of California, Berkeley, the Universities of Amsterdam and Utrecht in the Netherlands, and the Naval Science Laboratory in Washington, DC. Supernova scientists revealed the first X-ray spectra of SN 1989S, with unprecedented energy resolution. Research into globular clusters has shown that the highly dense stellar cores constitute a death trap for X-ray binary stars.

Together with graduate student Jon Miller, Lewin studied the X-ray binaries of black holes in our galaxy in great detail. The effect of general relativity on the iron-line emission close to the black hole’s “event horizon” was found by analyzing spectral distortions of the iron line (in X-rays). Black hole binaries are still being investigated using a variety of telescopes, including Chandra, the Rossi X-ray Timing Explorer (RXTE), and the European observatories XMM-Newton, Integral, and NuSTAR.

Lewin’s lectures on “Teaching Excellence” have been viewed over 12 million times on YouTube, iTunes U, and MIT’s own YouTube channel; even Bill Gates has acknowledged watching them multiple times.

As part of a lecture series sponsored by the Japanese Broadcasting Corporation, Lewin came out of retirement in the summer of 2012. (NHK). Lewin has been teaching physics at MIT for almost 43 years, and in that time he has incorporated numerous physics demonstrations into each of his classes. The eight TV broadcasts comprising the lectures first aired on NHK in Japan in 2013. In 2015, the series was released on DVD in Japan for region 2 with an optional partial English audio track and English subtitles.

Dutch astrophysicist Walter Hendrik Gustav Lewin (born January 29, 1936) taught physics at MIT for many years. After receiving his Ph.D. in nuclear physics from the Delft University of Technology in 1965, Lewin spent the next 43 years teaching physics at MIT before retiring in 2009.

The first revolving neutron star was discovered by Lewin using all-sky balloon surveys, and his work in X-ray detection was important in the discoveries made using satellites and observatories. Lewin is a renowned educator who has won accolades for his physics lectures, which he has made available for free online through platforms like YouTube, edX, and MIT OpenCourseWare.

After an internal inquiry concluded that Lewin had violated university policy by sexually assaulting a student in an online MITx course he taught in the fall of 2013, MIT stripped him of his Professor Emeritus designation in December 2014.

Lewin’s physics lectures, which he has made available on YouTube, edX, and MIT OpenCourseWare, have garnered him recognition as an educator and inspired others to pursue careers in education.

In 1936, in The Hague, the Netherlands, Lewin was born to Walter Simon Lewin and Pieternella Johanna van der Tang. During World War II, he was a kid when the Netherlands was occupied by Nazi Germany. His Jewish paternal grandparents Gustav and Emma Lewin may have perished in Auschwitz in 1942, or they may have succumbed to sickness or hunger. Lewin’s father took the family out of danger by disappearing one day without warning or explanation, leaving his mother to raise the kids alone.

While earning his doctorate, Walter Lewin worked as a high school physics teacher. He then joined the faculty at the Massachusetts Institute of Technology in January 1966 as a postdoctoral associate and was promoted to assistant professor. In 1968, he became an associate professor of physics, and in 1974 he became a full professor.

Together with George W. Clark, Lewin participated in all-sky balloon surveys while a student at MIT, where he also joined the X-ray astronomy group. About twenty balloon flights were accomplished in the late 1970s. Five new X-ray sources were found thanks to these balloon surveys; their spectra were considerably different from those seen in rocket investigations. These sources’ X-ray output varied throughout time. A periodicity of around 2.4 minutes was detected in the X-ray output from GX 1+4.

The first slowly rotating neutron star has been found. An X-ray flare was first noticed in October 1967, during observations of Scorpius X-1. In ten minutes, the flow increased by a factor of around 4, and then it began to fall again. There had previously been no evidence of X-ray variability, so this finding was particularly exciting. Since the rockets employed by other researchers could only stay in the air for a few minutes at a time, they missed the fact that the X-ray sources fluctuated on such small time scales.

Lewin collaborated on the Small Astronomy Satellite 3 (SAS-3) mission as a researcher. He oversaw the burst observation program and found multiple X-ray bursters, including the fast burster, which may generate thousands of X-ray bursts in a single day.

Lewin participated as a co-principal investigator on the HEAO-1 (A4) mission, which produced the first all-sky catalog in high-energy X-rays. Lewin conducted in-depth studies of optical bursts that are linked to X-ray bursts with H. Pedersen and J. van Paradijs, using SAS-3 and the Japanese observatory “Hakucho” to detect X-rays. Their combined observations of bursts showed that the optical bursts lagged after the X-ray bursts by a few seconds. Using this method, the radius of the accretion disc around the neutron stars was determined.

Working with colleagues in Amsterdam and Garching, Germany, Lewin used the European observatory EXOSAT as a guest observer in 1984 and 1985 to look for millisecond X-ray pulsations from low-mass X-ray binaries. Quasi-periodic oscillations (QPO) in the X-ray flux of GX 5-1 were found as a result. Lewin and his colleagues used the Japanese observatory “Ginga” to investigate the connection between the X-ray spectral state and the radio luminosity of a number of prominent low-mass X-ray binaries from 1989 to 1992.

Lewin played a crucial role in ROSAT’s observations of M31 and Messier 81, two neighboring galaxies. Lewin and his Ph.D. student Eugene Magnier has produced a catalog of 500,000 objects based on their deep optical charge-coupled device observations of M31 in four hues. As soon as SN 1993J was discovered in M81, Lewin and his doctoral student David Pooley began their successful X-ray observations.

From 1978 until Jan van Paradijs’s death in 2010, Lewin worked closely with his friend and colleague at the University of Amsterdam. They contributed to 150 publications as authors. It was also in 1993 that he was elected as a fellow of the American Physical Society and as a corresponding member of the Royal Netherlands Academy of Arts and Sciences.

Data from the Compton Gamma Ray Observatory has been the focus of Lewin and graduate student Jeffrey Kommers’ research (GRO). The BATSE Group from Alabama worked together on this. Chryssa Kouveliotou and I started working together in early December 1995.
The Greek astrophysicist and astronomer Chryssa Kouveliotou and the Dutch astronomer Van Paradijs identified a new kind of X-ray burst source, the Bursting Pulsar, for which they were awarded a NASA Achievement Award.

Lewin and his graduate student David Pooley performed considerable research on globular clusters and supernovae using the Chandra X-ray Observatory. Scientists from UW, IAS at Princeton University, Berkeley University, the Universities of Amsterdam and Utrecht in the Netherlands, and the Naval Research Laboratory in Washington, DC all worked together on this study. The first X-ray spectrum of supernova SN 1989S was obtained, and it had an exceptional energy resolution thanks to the investigation into these cosmic events. Extensive studies of globular clusters have shown that the high stellar densities at their centers “bake” X-ray binary stars.
