Amar Gopal Bose (Bengali : অমর বোস), (November 2, 1929 – July 12, 2013) was an American academic and entrepreneur. An electrical engineer and sound engineer, he was a professor at the Massachusetts Institute of Technology (MIT) for over 45 years. [1] He was also the founder and chairman of Bose Corporation. In 2011, he donated a majority of the company to MIT in the form of non-voting shares to sustain and advance MIT's education and research mission. [2]

Bengali language Indo-Aryan language mainly spoken in India and Bangladesh

Bengali, also known by its endonym Bangla, is an Indo-Aryan language primarily spoken by the Bengalis in South Asia. It is the official and most widely spoken language of Bangladesh and second most widely spoken of the 22 scheduled languages of India, behind Hindi. In 2015, 160 million speakers were reported for Bangladesh, and the 2011 Indian census counted another 100 million. With approximately 260–300 million total speakers worldwide, Bengali is the 6th most spoken language by number of native speakers and 7th most spoken language by total number of speakers in the world.

United States Federal republic in North America

The United States of America (USA), commonly known as the United States or America, is a country comprising 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.

Entrepreneurship is the process of designing, launching and running a new business, which is often initially a small business. The people who create these businesses are called entrepreneurs.


Early life and education

Bose was born in Philadelphia, Pennsylvania, [3] 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 [4] who, having been imprisoned for his political activities, fled Bengal in the 1920s in order to avoid further persecution by the British colonial police. [5] His mother, Charlotte, is described as an American schoolteacher of French and German ancestry, [6] but Bose described her as "more Bengali than me". She was a vegetarian and deeply interested in Vedanta and Hindu philosophy". [7]

United Kingdom Country in Europe

The United Kingdom (UK), officially the United Kingdom of Great Britain and Northern Ireland, and sometimes referred to as Britain, is a sovereign country located off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state, the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of 242,500 square kilometres (93,600 sq mi), the United Kingdom is the 78th-largest sovereign state in the world. It is also the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017.

Vedanta or Uttara Mīmāṃsā is one of the six (āstika) schools of Hindu philosophy. Vedanta literally means "end of the Vedas", reflecting ideas that emerged from the speculations and philosophies contained in the Upanishads. It does not stand for one comprehensive or unifying doctrine. Rather it is an umbrella term for many sub-traditions, ranging from dualism to non-dualism, all of which developed on the basis of a common textual connection called the Prasthanatrayi. The Prasthanatrayi is a collective term for the Principal Upanishads, the Brahma Sutras and the Bhagavad Gita.

Hindu philosophy various systems of thought in Hinduism

Hindu philosophy refers to a group of darśanas that emerged in ancient India. These include six systems (ṣaḍdarśana) – Sankhya, Yoga, Nyaya, Vaisheshika, Mimamsa and Vedanta. These are also called the Astika (orthodox) philosophical traditions and are those that accept the Vedas as an authoritative, important source of knowledge. Ancient and medieval India was also the source of philosophies that share philosophical concepts but rejected the Vedas, and these have been called nāstika Indian philosophies. Nāstika Indian philosophies include Buddhism, Jainism, Cārvāka, Ājīvika, and others.

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. [8]

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.

Abington Senior High School is a three-year co-educational high school in Abington, Pennsylvania, USA. The school was a two-year high school known as Abington South Campus from September 1964 until June 1983. In September 1983, Abington South Campus again became a three-year high school and eventually changed its name back to Abington Senior High. The 2016-2017 enrollment was 1,748. The principal is Mr. Angelo Berrios. Abington students are leaders in PSSA scores in the state of Pennsylvania and have won technology-oriented awards from Dell and Microsoft. Abington is most notable for its chess team, which has won the scholastic state championship numerous times and has won the scholastic national championship three times, with coach Shawn Simmons.

Massachusetts Institute of Technology University in Massachusetts

The Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts. The Institute is a land-grant, sea-grant, and space-grant university, with an urban campus that extends more than a mile alongside the Charles River. Founded in 1861 in response to the increasing industrialization of the United States, MIT adopted a European polytechnic university model and stressed laboratory instruction in applied science and engineering. It has since played a key role in the development of many aspects of modern science, engineering, mathematics, and technology, and is widely known for its innovation and academic strength, making it one of the most prestigious institutions of higher learning in the world.

The Philips Natuurkundig Laboratorium or NatLab was the Dutch section of the Philips research department, which did research for the product divisions of that company. Originally located in the Strijp district of Eindhoven, the facility moved to Waalre in the early 1960s. A 1972 municipal rezoning brought the facility back into Eindhoven, which was followed some years later by Eindhoven renaming the street the facility is on into the Prof. Holstlaan, after the first director.


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.

Loudspeaker transducer that converts electrical energy into sound energy; electroacoustic transducer; converts an electrical audio signal into a corresponding sound

A loudspeaker is an electroacoustic transducer; a device which converts an electrical audio signal into a corresponding sound. The most widely used type of speaker in the 2010s is the dynamic speaker, invented in 1925 by Edward W. Kellogg and Chester W. Rice. The dynamic speaker operates on the same basic principle as a dynamic microphone, but in reverse, to produce sound from an electrical signal. When an alternating current electrical audio signal is applied to its voice coil, a coil of wire suspended in a circular gap between the poles of a permanent magnet, the coil is forced to move rapidly back and forth due to Faraday's law of induction, which causes a diaphragm attached to the coil to move back and forth, pushing on the air to create sound waves. Besides this most common method, there are several alternative technologies that can be used to convert an electrical signal into sound. The sound source must be amplified or strengthened with an audio power amplifier before the signal is sent to the speaker.

Acoustics science that deals with the study of all mechanical waves in gases, liquids, and solids including vibration, sound, ultrasound and infrasound

Acoustics is the branch of physics that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries.

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.

Patent Intellectual property conferring a monopoly on a new invention

A patent is a form of intellectual property that gives its owner the legal right to exclude others from making, using, selling, and importing an invention for a limited period of years, in exchange for publishing an enabling public disclosure of the invention. In most countries patent rights fall under civil law and the patent holder needs to sue someone infringing the patent in order to enforce his or her rights. In some industries patents are an essential form of competitive advantage; in others they are irrelevant.

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." [9]

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. [9]

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." [10]

In 2007, he was listed in Forbes 400 as the 271st richest man in the world, with a net worth of $1.8 billion. [11] 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. [12]

Personal life

He married Prema Bose but they later divorced.[ when? ] 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. [13] Vanu Bose was the founder and CEO of a software-defined radio technology company. [14]

Bose died on July 12, 2013 at the age of 83 in Wayland, Massachusetts. [1] [15] [16]

Teaching and Legacy

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. [17] Former students have stated that his classes helped them gain life skills and problem solving skills that have served them throughout their careers. [1]

In 2011, Bose donated a majority of the company's non-voting shares to MIT on the condition that the shares never be sold. [18] Because these shares are non-voting, MIT does not participate in operations or governance of Bose Corporation. [17]
