Life Senior Member, 97; died 10 April
Jon Löf was professor emeritus of electrical engineering at the University of Connecticut (UConn), in Storrs.
He joined the university in 1952 as an assistant professor of electrical engineering. Löf helped found the university’s Computer Center and served as its director from the early 1960s until he retired in 1976. He was then named professor emeritus and continued to work at the center, helping train students to use the university’s computers and software programs.
Löf made a bequest of US $1 million to the UConn Foundation, which will help fund the university’s school of engineering.
A member of the IEEE Computer Society, Löf received a bachelor’s degree in electrical engineering from the University of Denver. He earned a master’s degree in 1942 from MIT.
Fellow, 58; died 22 April
David Notkin was a professor of computer science and engineering at the University of Washington, in Seattle. He died of cancer.
He joined the university as a professor in 1984 and served as chair of its computer science and engineering department from 2001 to 2006. In 2003, Notkin helped found the school’s Paul G. Allen Center for Computer Science and Engineering. Last year, he was named acting associate dean of research and graduate studies.
His research focused on software engineering, with a particular emphasis on reducing the difficulties and cost associated with changing and updating software.
Notkin was a member of the IEEE Computer Society. He received a bachelor’s degree in 1977 from Brown University, in Providence, R.I. He went on to earn a Ph.D. in 1984 from Carnegie Mellon University, in Pittsburgh.
Lawrence Elliot Kugel
Member, 71; died 2 May
Lawrence Elliot Kugel was a research scientist at IBM’s T.J. Watson Research Center, in Yorktown Heights, N.Y.
During his 30 years at the company, he helped develop the first “six degrees of freedom” joystick, used in 3-D design programs to move objects on screen in six directions: backward, forward, left, right, up, and down. He also helped develop IBM’s Electronic Circuit Analysis Program II software for investigating the behavior of electronic circuits.
After retiring, Kugel worked as a contractor specializing in 3-D mechanical design for Gulfstream Aerospace, an aircraft designer, in Savannah, Ga., and Prodigy, an engineering firm, in Bowie, Md.
Kugel received a bachelor’s degree in electrical engineering from Union College, in Schenectady, N.Y. He earned a master’s degree, also in EE, from the University of Wisconsin, in Madison.
Founder and CEO of Joseph R. Loring & Associates
Life Member, 86; died 30 May
Joseph Loring founded his engineering consultancy in New York City in 1956. It now also has offices in Washington, D.C., and Princeton, N.J. He served as CEO until he retired in October.
The company renovated the mechanical and electrical systems for several buildings in Washington, D.C., including ones housing the U.S. Supreme Court and the U.S. Department of Health, Education, and Welfare. It also did electrical engineering work for the World Trade Center and designed one of the terminals at John F. Kennedy International Airport, both in New York City.
Loring earned a bachelor’s degree in electrical engineering in 1947 from Virginia Tech.
The following person was not an IEEE member but did pioneering work in an IEEE field of interest.
Nobel Prize recipient
86; died 16 May
Heinrich Rohrer and his colleague, Gerd Binnig, received the 1986 Nobel Prize in Physics for developing a microscope so powerful that, for the first time, individual atoms could be seen on the surface of materials.
He joined the IBM Research Laboratory, in Rüschlikon, Sweden, in 1963, where he investigated semiconductor and magnetic materials. In 1981, Rohrer codeveloped the scanning tunneling microscope, a device in which an electrical probe with a tungsten needle is brought extremely close (about one billionth of a meter) to the surface of the object being studied. The probe detects electrical currents between the tip of the needle while the surface is being scanned and individual atoms can be detected. The microscope could not only visualize tiny atomic objects but also measure their sizes and manipulate them, which helped usher in the field of nanotechnology.
Rohrer retired in 1997 as head of the physics department at IBM. He received a bachelor’s degree and a Ph.D., both in physics, from the Swiss Federal Institute of Technology, in Zurich.
