Early life

Viterbi was born in Bergamo, Italy to Italian Jewish parents and emigrated with them in 1939 to the United States as a refugee because of the Italian racial laws. His original name was Andrea, but when he was naturalized in the US, his parents anglicized it to Andrew.

Education

Viterbi attended the Boston Latin School, and then entered MIT in 1952, studying electrical engineering. He received both BS and MS in electrical engineering in 1957 from MIT.

He worked at Raytheon and later at Jet Propulsion Laboratory in Pasadena, where he started working on telemetry for guided missiles, also helping to develop the phase-locked loop. Simultaneously, he was carrying out a PhD study at the University of Southern California, where he graduated in 1963 in digital communications.[2]

Further career

After receiving his PhD, he applied successfully for an academic position at University of California, Los Angeles (UCLA).

Viterbi was later a professor of electrical engineering at UCLA and UCSD. In 1967 he proposed the Viterbi algorithm to decode convolutionally encoded data. It is still used widely in cellular phones for error correcting codes, as well as for speech recognition, DNA analysis, and many other applications of Hidden Markov models. On advice of a lawyer, Viterbi did not patent the algorithm.[3] Viterbi also helped to develop the CDMA standard for cell phone networks.

Viterbi was the cofounder of Linkabit Corporation, with Irwin Jacobs in 1968, a small military contractor. He was also the co-founder of Qualcomm Inc. with Jacobs in 1985. As of 2003, he is the president of the venture capital company The Viterbi Group. He continues to be involved in wireless communications technology companies as a strategic advisor to Ingenu's board of directors.[4]

In 1998 he was one of the few receiving a Golden Jubilee Award for Technological Innovation from the IEEE Information Theory Society. Viterbi earned it for "the invention of the Viterbi algorithm".[5] In 2002, Viterbi dedicated the Andrew Viterbi '52 Computer Center at his alma mater, Boston Latin School. On March 2, 2004, the University of Southern California School of Engineering was renamed the Viterbi School of Engineering in his honor, following his $52 million donation to the school.[6] He is a member of the USC Board of Trustees.[7]

He is also on the Board of Trustees at The Scripps Research Institute.

He is also founding member of ISSNAF (The Italian Scientists and Scholars in North America Foundation).

In 2005, he was awarded the Benjamin Franklin Medal in Electrical Engineering.

Viterbi and Irwin M. Jacobs received the 2007 IEEE/RSE Wolfson James Clerk Maxwell Award, for "fundamental contributions, innovation, and leadership that enabled the growth of wireless telecommunications".[8]

In September 2008, he was awarded the National Medal of Science for developing "the 'Viterbi algorithm', and for his contributions to Code Division Multiple Access (CDMA) wireless technology that transformed the theory and practice of digital communications".

In 2010, he received the IEEE Medal of Honor and in the same year he also received the IIC Lifetime Achievement Award by the Italian Cultural Institute of Los Angeles. In 2011, he received the John Fritz Medal from the American Association of Engineering Societies.[9]

In 2013, Viterbi was inducted into the National Inventors Hall of Fame.

In 2017, Viterbi, along with Irwin Jacobs, received the IEEE Milestone Award for their CDMA and spread spectrum development that drives the mobile industry.[10]

Personal life

Viterbi was married to Erna Finci (1934–2015),[11] with whom he had three children. On November 2, 2011, Viterbi's son, Alexander, died of a heart attack in Mammoth Lakes, California at the age of 40.[12]

IEEE Medal of Honor

The IEEE Medal of Honor is the highest recognition of the Institute of Electrical and Electronics Engineers (IEEE). It has been awarded since 1917, when its first recipient was Major Edwin H. Armstrong. It is given for an exceptional contribution or an extraordinary career in the IEEE fields of interest. The award consists of a gold medal, bronze replica, certificate and honorarium. The Medal of Honor may only be awarded to an individual.

The medal was created by the Institute of Radio Engineers (IRE) as the IRE Medal of Honor. It became the IEEE Medal of Honor when IRE merged with the American Institute of Electrical Engineers (AIEE) to form the IEEE in 1963. It was decided that IRE's Medal of Honor would be presented as IEEE's highest award, while the Edison Medal would become IEEE's principal medal.

Ten persons with an exceptional career in electrical engineering received both the IEEE Edison Medal and the IEEE Medal of Honor, namely Edwin Howard Armstrong, Ernst Alexanderson, Mihajlo Pupin, Arthur E. Kennelly, Vladimir K. Zworykin, John R. Pierce, Sidney Darlington, Nick Holonyak, Robert H. Dennard, Dave Forney, and Kees Schouhamer Immink.

Originally, the Foundation was located at the Aspen Institute. In 1997, it relocated, by invitation, to Columbia University's Fu School of Engineering and Applied Science.

Mason's invariant

In electronics, Mason's invariant, named after Samuel Jefferson Mason, is a measure of the quality of transistors.

"When trying to solve a seemingly difficult problem, Sam said to concentrate on the easier ones first; the rest, including the hardest ones, will follow," recalled Andrew Viterbi, co-founder and former vice-president of Qualcomm. He had been a thesis advisee under Samuel Mason at MIT, and this was one lesson he especially remembered from his professor. A few years earlier, Mason had heeded his own advice when he defined a unilateral power gain for a linear two-port device, or U. After concentrating on easier problems with power gain in feedback amplifiers, a figure of merit for all three-terminal devices followed that is still used today as Mason's Invariant.
