Bose was born in Philadelphia, PA, to a Bengali Hindu father, Noni Gopal Bose and an American mother of French and German ancestry, Charlotte. His father was an Indian freedom revolutionary who, having been imprisoned for his political activities, fled Bengal in the 1920s in order to avoid further persecution by the British colonial police. His mother, Charlotte, is described as an American schoolteacher of French and German ancestry, but Bose described her as "more Bengali than me. She was a vegetarian and deeply interested in Vedanta and Hindu philosophy".
Bose first displayed his entrepreneurial skills and his interest in electronics at age thirteen when, during the World War II years, he enlisted school friends as co-workers in a small home business repairing model trains and home radios, to supplement his family's income.
After graduating from Abington Senior High School in Abington, Pennsylvania, Bose enrolled at the Massachusetts Institute of Technology, graduating with an SB (Bachelor of Science) in Electrical Engineering in the early 1950s. Bose spent a year at Philips Natuurkundig Laboratorium in Eindhoven, Netherlands; and a year as a Fulbright research student in New Delhi, India, where he met his future first wife. He completed his PhD in Electrical Engineering from MIT, writing a thesis on non-linear systems under the supervision of Norbert Wiener and Yuk-Wing Lee.
Following graduation, Amar Bose became an assistant professor at the Massachusetts Institute of Technology. During his early years as a professor, Bose bought a high-end stereo speaker system in 1956 and he was disappointed to find that speakers with impressive technical specifications failed to reproduce the realism of a live performance. This would eventually motivate his extensive speaker technology research, concentrating on key weaknesses in the high-end speaker systems available at the time. His research on acoustics led him to invent a stereo loudspeaker that would reproduce, in a domestic setting, the dominantly reflected sound field that characterizes the listening space of the audience in a concert hall. His focus on psychoacoustics later became a hallmark of his company's audio products.
For initial capital to fund his company in 1964, Bose turned to angel investors, including his MIT thesis advisor and professor, Y. W. Lee. Bose was awarded significant patents in two fields that continue to be important to the Bose Corporation. These patents were in the area of loudspeaker design and non-linear, two-state modulated, Class-D power processing.
The company Bose founded employed 11,700 people worldwide as of 2016 and produces products for home, car, and professional audio, as well as conducting basic research in acoustics and other fields. Bose never took his company public, and since the company was privately held Bose was able to pursue risky long-term research. In a 2004 interview in Popular Science magazine, he said: "I would have been fired a hundred times at a company run by MBAs. But I never went into business to make money. I went into business so that I could do interesting things that hadn't been done before."
Starting in the 1980s, Bose developed an electromagnetic replacement for automotive shock absorbers, intended to radically improve the performance of automotive suspension systems, absorbing bumps and road shock while controlling car body motions and sway.
Bose said that his best ideas usually came to him in a flash. "These innovations are not the result of rational thought; it's an intuitive idea."
In 2007, he was listed in Forbes 400 as the 271st richest man in the world, with a net worth of $1.8 billion. In 2009, he was no longer on the billionaires list, but returned to the list in 2011, with a net worth of $1.0 billion.
He married Prema Bose but they later divorced. They had two children, Vanu and Maya. He had one grandchild, Kamala. Amar Bose did not practice any religion, though he used to meditate for a short while every day. Vanu Bose was the founder and CEO of a software-defined radio technology company.
In addition to running his company, Bose remained a professor at MIT until 2001. He earned the Baker Teaching Award in 1963–64, and further teaching awards over the years. The Bose Award for Excellence in Teaching (1989), and later the Junior Bose Award (1995) were established in his honor, to recognize outstanding teaching in the MIT School of Engineering.
In 2011, Bose donated a majority of the company's non-voting shares to MIT on the condition that the shares never be sold. Because these shares are non-voting, MIT does not participate in operations or governance of Bose Corporation.

Bose or Basu or Boshu is a surname found amongst Bengali Hindus. It stems from Sanskrit वासु vāsu (a name of Vishṇu meaning 'dwelling in all beings').Boses belong to Kayastha caste in Bengal. The Bengali Kayasthas evolved between the 5th/6th century AD and 11th/12th century AD, its component elements being putative Kshatriyas and mostly Brahmin. Boses are considered as Kulin Kayasthas, along with Ghoshes, Mitras and Guhas.Bose Corporation
Bose Corporation is a privately held American corporation, based in Framingham, Massachusetts, that designs, develops and sells audio equipment. Founded in 1964 by Amar Bose, the company sells its products throughout the world. According to the company annual report in the 2017 financial year, Bose received revenue of US$3.8 billion and employed more than 8,000 people.
Bose is best known for its home audio systems and speakers, noise cancelling headphones, professional audio systems and automobile sound systems. The company has also conducted research into suspension technologies for cars and heavy-duty trucks and into the subject of cold fusion. Bose has a reputation for being particularly protective of its patents, trademarks, and brands.
A majority of Bose Corporation's non-voting shares were given by Amar Bose in 2011 to his alma mater and former employer, the Massachusetts Institute of Technology. They receive cash dividends, but are prohibited from selling the shares and are unable to participate in the management and governance of the company.Crutchfield Corporation
Crutchfield Corporation is a North American retailer specializing in a wide range of electronics, including mobile audio and video equipment for the automobile, along with speakers, televisions, and other electronics for home or portable use, serving both the United States and Canada.
It was created in 1974 by William G. " Bill" Crutchfield, Jr., founder and CEO. It is based in Charlottesville, Virginia.FMX (broadcasting)
FMX is the name of a commercially unsuccessful noise reduction system developed in the 1980s for FM broadcasting in the United States.
FM stereo broadcasting is known to incur up to a 23 dB noise penalty over that of monophonic FM broadcasting; this is due to the combination of the triangular FM noise spectrum and the wider baseband bandwidth occupied by the stereo multiplex signal. Developed at the CBS Technology Center, FMX was intended to improve this characteristic for listeners in the fringe areas where the noise penalty would be worst. This improvement was achieved by adding an amplitude-compressed version of the L−R (left-minus-right, or difference) signal modulated in quadrature with the stereo subcarrier, using a version of the CX noise-reduction system originally developed at CBS for LP records.
Upon his accession as Chairman of CBS, Laurence Tisch closed the CBS labs in 1986, whereupon the FMX intellectual property was spun off to an investment group, under the name Broadcast Technology Partners (BTP).
With about 50 stations using the technology and perhaps another 50 committed, a controversy emerged in 1989 when MIT professor and Bose Corporation CEO Amar Bose and Bose engineer William Short released a critical study, finding the system to have the potential to "seriously degrade the quality of stereo reception whether received by FMX equipment or not." According to the study, the heavy compression of the L−R audio caused interference in receivers under multipath conditions. A BTP spokesman rebutted the finding, saying that the Bose analysis exaggerated a "worst-case scenario", and actually employed "flawed mathematics" to attempt to prove their point. Perhaps not coincidentally, a patent application filed earlier by Bose disclosed an invention whose implementation was incompatible with the adoption of FMX, while another – filed by Bose and Short around the time of the release of the critical study – sought to improve the performance of FMX under multipath conditions.Despite industrial supporters in both the broadcast and consumer electronics industries, the system never achieved a critical mass, and faded into obscurity. However, numerous related patents have since been applied for or granted, referencing the original FMX patents.Lee Yuk-Wing
Lee Yuk-Wing (Chinese: 李郁榮; April 14, 1904 – November 8, 1989) was a Professor of Electrical Engineering at the Massachusetts Institute of Technology. He is best known for adapting and popularizing the pioneering work of Norbert Wiener and for his own research on statistical communication theory.
Lee was born in Macao and called “Yuwing” or “YW” by his friends. He was a longtime collaborator of Wiener. Lee was part of a cohort of students sponsored by the Boxer Indemnity Scholarship Program. After obtaining his doctorate at MIT, he returned to China and taught at Tsinghua University. He invited Wiener there in 1935-1937. In 1946 he came back to MIT as a Visiting Professor and initiated his research on statistical communication theory. He then stayed at MIT for 30 years. John Costas, Harry L. Van Trees, Irwin Jacobs and Amar Bose were his students at MIT. He died in San Mateo, California.List of people from New England

The Marxist Forward Bloc is a political party in India, a splinter group of the All India Forward Bloc. The MFB was formed in 1953 as Satyapriya Banerjee, a member of the AIFB Central Secretariat, Amar Bose, Suhurit Chaudhury and Ram Chatterji were expelled from AIFB. At its foundation, Satyapriya Banerjee was the party's general secretary and Amar Bose its chairman.
The MFB is part of the Left Front and has been associated with the combined left movement since its inception. Its leader Ram Chatterjee was a minister in the West Bengal Left Front government for several years. Today the MFB is led by Pratim Chatterjee, who served in the West Bengal government as Minister of Fire Services. Chatterjee represented the Tarakeswar seat in the West Bengal Legislative Assembly until 2011.
In West Bengal Assembly elections, the MFB contests the seats for Tarakeswar in Hoogly district and Jamalpur in Burdwan district as a Left Front partner. In the 2006 West Bengal Legislative Assembly election, the party retained both seats. In the Kolkata municipal polls in 2005, the MFB contested two wards as a Left Front partner. Biren Chakroborty, the secretary of the MFB, was elected from ward number 57.
In the 2008 Panchayet polls, the MFB won seats in Panchayet, Panchayet Samity and ZP levels in Hoogly and Burdwan districts.
In the 2010 municipal polls, the MFB lost its seat in Kolkata corporation. It won a seat each at Rampurhat in Birbhum and Arambagh in Hooghly.
The party lost its representation in the Legislative Assembly in the 2011 election. from 2014 jaihind singh is the chair person.Norbert Wiener
Norbert Wiener (November 26, 1894 – March 18, 1964) was an American mathematician and philosopher. He was a professor of mathematics at the Massachusetts Institute of Technology (MIT). A child prodigy, Wiener later became an early researcher in stochastic and mathematical noise processes, contributing work relevant to electronic engineering, electronic communication, and control systems.
Wiener is considered the originator of cybernetics, a formalization of the notion of feedback, with implications for engineering, systems control, computer science, biology, neuroscience, philosophy, and the organization of society.
Norbert Wiener is credited as being one of the first to theorize that all intelligent behavior was the result of feedback mechanisms, that could possibly be simulated by machines and was an important early step towards the development of modern AI.November 2

Thomas Greenway Stockham (December 22, 1933 – January 6, 2004) was an American scientist who developed one of the first practical digital audio recording systems, and pioneered techniques for digital audio recording and processing as well.
Stockham was born in Passaic, New Jersey. Stockham attended Montclair Kimberley Academy, graduating in the class of 1951. Known as the "father of digital recording", he earned an Sc.D. degree from the Massachusetts Institute of Technology in 1959 and was appointed Assistant Professor of Electrical Engineering. Early in his academic career at MIT, Stockham worked closely with Amar Bose, founder of Bose Corporation, on the use of digital computers for measurement and simulation of room acoustics and for audio recording and enhancement. While at MIT, he noticed several of the students using an MIT Lincoln Laboratory TX-0 mainframe computer installed at the campus to record their voices digitally into the computer's memory, using a microphone and a loudspeaker connected to an A/D-D/A converter attached to the TX-0. This expensive tape recorder led Stockham to his own digital audio experiments on this same computer in 1962.
In 1968 he left MIT for the University of Utah, and in 1975 founded Soundstream, Inc. The company developed a 16-bit digital audio recording system using a 16-track Honeywell instrumentation tape recorder as a transport, connected to digital audio recording and playback hardware of Stockham's design. It ran at a sampling rate of 50 kHz, as opposed to the audio CD sampling rate of 44.1 kHz.
Soundstream Inc. was the first commercial digital recording company in the United States, located in Salt Lake City. Stockham was the first to make a commercial digital recording, using his own Soundstream recorder in 1976 at the Santa Fe Opera. In 1980, Soundstream merged with the Digital Recording Company (DRC) and became DRC/Soundstream.
Stockham played a key role in the digital restoration of Enrico Caruso recordings, described in a 1975 IEEE paper. These acoustic recordings were the first to be digitally restored by computer, and were released on the album Caruso - A Legendary Performer, issued in 1976 by RCA Records.
In 1974, he investigated President Richard Nixon's White House tapes, alongside fellow members of the panel of persons nominated jointly by the White House and the Special Prosecution Force. It was he who discovered that the 18 minutes of erasures were not accidental, as Nixon's secretary Rosemary Woods claimed. Stockham was able to discern several distinct erasures and even determined the order of erasure.
Stockham's team reached agreement on seven conclusions detailed in their 87-page report to Chief Judge John J. Sirica:
1. The erasing and recording operations that produced the buzz
section were done directly on the evidence tape.2. The Uher 5000 recorder designated Government Exhibit #60 probably produced the entire buzz section.3. The erasures and buzz recordings were done in at least five, and perhaps as many as nine, separate and contiguous segments.4. Erasure and recording of each segment required hand operation of keyboard controls on the Uher 5000 machine.5. Erased portions of the tape probably contained speech originally.6. Recovery of the speech is not possible by any method known to us.7. The evidence tape, insofar as we have determined, is an original and not a copy.
Stockham's developments and contributions to digital audio paved the way for later digital audio technologies, such as the audio compact disc and Digital Audio Tape.
Stockham received wide recognition for his pioneering contributions to digital audio. He received, among many others, the Gold Medal award from the Audio Engineering Society in 1987, a Technical Emmy award in 1988, the Poniatoff Gold Medal from the Society of Motion Picture and Television Engineers, a Grammy award from NARAS in 1994, the IEEE Jack S. Kilby Signal Processing Medal in 1998 and a Scientific and Engineering award from the Academy of Motion Picture Arts and Sciences in 1999.Vanu Bose
