Inventor of AT&T’s Datakit, the First Virtual Connection Switch, Dies at 85

Alexander “Sandy” Fraser

Developer of the first digital circuit network change

Fellow, 85 died 13 June

Fraser created the Datakit, the very first digital circuit community change, whilst operating at AT&T Labs in Florham Park, N.J. The telecommunications engineering is employed by all big U.S. telephone corporations.

He invented other pioneering systems as properly, including the file program for the Titan supercomputer (prototype of Atlas 2), cell-primarily based networks (precursor to asynchronous transfer manner), and the Euphony processor, which was just one of the initial method-on-a-chip microprocessors.

He commenced his vocation at Ferranti, an electrical engineering and equipment business in Manchester, England. He remaining there in 1966 to sign up for the University of Cambridge as an assistant director of investigate. After a few many years, he moved to the United States to work for AT&T Bell Labs in Holmdel, N.J. When there, he helped acquire the Transferring Photograph Authorities Team Sophisticated Audio Coder, which compresses music signals. Initial utilized in Apple’s iTunes software, it now can be found in all smartphones.

Fraser held quite a few management positions at the enterprise all through his 30 a long time there. He grew to become director of the Computing Science Investigation Center in 1982 and 5 decades later was promoted to government director. In 1994 he grew to become associate vice president for the company’s details science analysis office. In 1996 he served establish AT&T Labs in Florham Park. It is the company’s study and progress division, of which he was vice president for two years.

He made the decision to emphasis additional on study and still left his posture as vice president. AT&T named him main scientist, and in that place he worked on building architecture and protocols for a big-scale Net so that clients could hook up to it from their properties.

In 2002 Fraser retired and founded Fraser Study, in Princeton, N.J., in which he ongoing his networking do the job.

He earned his bachelor’s degree in aeronautical engineering in 1958 from the College of Bristol, in England. He went on to receive a Ph.D. in computing science in 1969 from Cambridge.

Byung-Gook Park

Vice chair of IEEE Area 10

Fellow, 62 died 20 Could

Park was an active IEEE volunteer and was serving as the 2021–2022 vice chair of IEEE Location 10 at the time of his demise. He was the 2014–2015 chair of the IEEE Seoul Segment.

He was a member of several committees at conferences together with the IEEE International Electron Units Meeting, the Intercontinental Meeting on Solid Condition Gadgets and Elements, and the Global Specialized Conference on Circuits/ Programs, Computer systems, and Communications.

He served as editor ofIEEE Electron Gadget Letters and editor in chief of theJournal of Semiconductor Technological innovation and Science.

From 1990 to 1993, he labored at AT&T Bell Labs in Murray Hill, N.J., before joining Texas Devices in Dallas. Following one particular year, he left the company and joined Seoul Countrywide University as an assistant professor of electrical and computer engineering. He labored at the college at the time of his loss of life.

His investigate pursuits included the style and design and fabrication of neuromorphic equipment and circuits, flash reminiscences, and silicon quantum gadgets.

Park authored or coauthored far more than 1,200 research papers. He was granted 107 patents in Korea and 46 U.S. patents.

He gained bachelor’s and master’s degrees in electronics engineering from Seoul Nationwide University in 1982 and 1984, respectively, and a Ph.D. in EE in 1990 from Stanford.

David Ellis Hepburn

Earlier vice chair of IEEE Canada’s Instructor-in-Assistance Plan

Everyday living senior member, 91 died 25 March

Hepburn was a potent proponent of preuniversity training and relished supporting shape the subsequent generation of engineers. He was concerned with IEEE Canada’s Trainer-in-Assistance Method, an initiative that aims to enhance elementary and secondary faculty technical instruction by providing teachers lesson options and schooling workshops. He served as vice chair of the program’s committee. He was honored for his contributions with the 2017 IEEE Canada Presidents’ Make-a-Change Award.

He was an lively volunteer for TryEngineering, a web-site that gives instructors, mother and father, and students with engineering means. These involve arms-on classroom routines, lesson options, and details about engineering professions and college plans. He wrote 6 classes, which cover transformers, AC and DC motors, magnetism, binary basic principles, and solar ability.

Though a college student at Staffordshire College, in England, he was an intern at electrical devices maker English Electrical in Stafford. Five a long time after graduating in 1952, he joined utility firm Hydro-Québec in Montreal as a units layout engineer. In 1965 he went to perform for consulting firm Acres Intercontinental in Montreal. His to start with assignment there was with the design and style and construction crew for the Churchill Falls underground hydroelectric electric power station, in Labrador, Nfld.

In 1969 he was tasked with helping to establish transmission strains in Bangladesh that related the country’s jap and western electrical grids. He and his loved ones lived there for two yrs.

After that, Hepburn continued to work on global assignments in nations around the world together with Indonesia, Nepal, and Pakistan.

Adhering to his retirement in 1994, he worked as a advisor for corporations including the Environment Financial institution and the Canadian International Enhancement Company. He also volunteered for the Canadian Govt Support Group, a nonprofit that provides underserved communities throughout the world with mentorship, coaching, and coaching in sectors these as alternate strength, forestry, and production. He volunteered on projects in Guatemala and Honduras.

Markus Zahn

Professor emeritus at MIT

Daily life Fellow, 75 died 13 March

Zahn was a professor of electrical engineering for 50 years. He taught at the University of Florida in Gainesville in 1970 and labored there for 10 a long time in advance of becoming a member of MIT, the place he invested the remainder of his job.

He researched how electromagnetic fields interact with materials, and he produced a technique for magnetically separating oil and drinking water, as effectively as a process that detects buried dielectric, magnetic, and conducting devices these types of as land mines.

He was director of MIT’s 6-A plan, which offers undergraduate learners with mentoring and internship chances.

Zahn, who was granted extra than 20 U.S. patents, worked as a specialist for Dow, Ford, Texas Instruments, and other organizations

He acquired bachelor’s, master’s, and doctoral degrees in engineering from MIT.
