Milton Feng


Milton Feng was born in Taiwan, China on July 21, 1950. He graduated from Columbia University in 1976 with a B.S. in Electrical Engineering and his M.S, 1976 and his PhD, 1979 at the University of Illinois Urban Champaign in Electrical Engineering. Feng worked from 1979 to 1983, as the head of the materials and device group at Torrance Research Center, Hughes Aircraft Company, Torrance, CA. While working at the Torrance Research Center he developed an ion implanted low noise and power MESFET and MMIC for radar applications. He would go onto work for the Ford Microelectronic, Inc., researching digital integrated circuit development.
In 1991, he took a position at the University of Urbana Champaign as an electrical and computer engineering professor and a research professor at the Microelectronic Laboratory and has worked on a variety of projects. In 2003 he developed the words fastest transistor, 2004 the Light emitting transistor, and the Transistor Laser with Nick Holonyak. He has also published over 237 papers and holds over 35 U.S patents in semiconductor microelectronics, and is a IEEE and a OSA Fellow. Over the course of his life he has received numerous awards honoring his contributions to the field of electrical engineering.

William J Fry


William J Fry was born on April 14, 1918 in Johnstown, PA. In 1940, Fry graduated with a bachelor’s of science from Pennsylvania State University. During the Second World War, Fry worked at the Naval Research Laboratory on underwater sound. After the war ended, Fry was hired by William Everitt to the University of Illinois Urbana Champaign electrical engineering research department. At the University, Fry established his Bioacoustics Research Laboratory.



Fry’s primary focus of research was the usage of ultrasound for non-invasive surgical procedures. When Fry first came to the University, Fry had to build most of his own instruments. His specially built equipment allowed him to study the effects that ultrasound had on animal tissue4. One of Fry’s experiments, using feline adrenal glands, showed that ultrasound does indeed affect animal tissues. Fry’s report on feline experiments led to the approval of ultrasound use on women with late stage breast cancer. Fry bombarded their pituitaries with ultra sound, and while 4 out of the 5 patients
 exhibited no reaction, the fifth was able to live for 20 months longer under the procedure. Another human trial was performed in junction with the University Of Iowa Department Of Neurosurgery, where a successful operation using ultrasound was performed on a Parkinson’s patient.
In addition to using ultrasound for therapeutic purposes, Fry also wanted to use ultrasound as a noninvasive imaging technique to better study the human nervous system. Not only limited to ultrasound, Fry and his brother also worked on the development of an artificial heart. Fry and his colleagues had been able to keep a dog alive for over 9 hours without its biological heart, using a mechanical replacement.
On July 21, 1968, Fry passed away of a heart attack at the age of 50. Much of Fry’s work served as predecessors to later work in their respective fields. He was one of the first to suggest a type of radiation for the treatment of tumors, his brother continued his imaging work which led to the first scanning and imaging of live brains4, and mechanical hearts are now a reality.

Raymond H. DuHamel

Raymond H. DuHamel, was born in Tuscola, Illinois, the son of S.S and Florence Maris DuHamel. He attended Springfield High school and earned his Doctoral in Electrical Engineering from the University of Illinois Urbana Champaign. Upon completion of his degree he obtained a position in the engineering department in antenna research. Where he added in the development of the Conical Logarithmic Spiral antenna.



Toothed bow tie
Working with Victor Rumsey and John Dyson the trio went to work developing a high speed frequency independent antenna for the United States military.  DuHamel suggested that by straightening Rumsey’s spiral so that is was in the shape of a triangle and added teeth and slots to the antenna. The end result was Duhamel’s “toothed bow tie” also known as the “log-periodic” antenna it was thought to be frequency independent. However after countless tests they discovered that this was not true and that it had the same limitations as the equiangular spiral.

John Dyson

John Dyson, born in August 9, 1918 in Lemmon, South Dakota to Clarence Austin and Flora Wittman Dyson. He earned his bachelor’s degree in Economics in 1940 and Electrical Engineering in 1949 from South Dakota State University. He would go on to obtain his doctorate in Electrical Engineering at the University of Illinois Urban Champaign in 1957. Upon completing his doctoral degree he was appointed to a position researching radiomagnetics and antennas at the University of Illinois Urbana Champaign. After numerous experiments he developed the conical logarithmic spiral antenna used in radio telescopes. The log-spiral antenna has a circularly polarized receiving pattern which enables it to aim the receiving beams of the telescope.
