Cornelius N. Weygandt, EE’28 GrE’47, Emeritus Professor of Systems Engineering, 
passed away on August 8, 2004, just five days short of his 100th birthday. He earned 
his bachelor’s degree from Penn’s Moore School of Electrical Engineering, then under 
the leadership of Harold Pender. 

He worked for General Electric and Brooke Engineering Company before joining the 
faculty at Penn in 1935. He received his Ph.D. in 1947 from Penn and became full 
professor in 1954. One of Dr. Weygandt’s most relevant contributions to The Moore 
School was to help create a path to electronic computing a decade before the ENIAC 
was birthed. Dr. Weygandt’s work improved the accuracy of the differential analyzer 
by inserting an electronic component into an otherwise mechanical device. The 
resulting high performance raised Penn’s role in computation and led to the 
development of ENIAC. 

Professor Weygandt provided strong leadership of graduate education. In 1968 The 
Moore School graduated one of the largest groups of Ph.D.’s in Electrical Engineering 
in the country, thanks in large part to his dedication to his students, who knew him as 
a highly effective teacher and a caring advisor. 

In addition to his wife, Dr. Weygandt is survived by a daughter, Betty Davies, a son, 
Neil; two grandchildren; and two great-grandchildren. 

From http://www.upenn.edu/gazette/1104/1104obits.html:

Dr. Cornelius N. Weygandt EE’28 GrE’47, Haverford, Pa., professor emeritus of 
engineering and former chair of the graduate division of engineering at the University; 
Aug. 8. He began his career at General Electric and Brooke Engineering Co. before 
coming to Penn in 1935 as an instructor at the Moore School He became professor in 
1954 and served as section head of the instrumentation and control section at the 
Moore School. In 1973 he received a secondary appointment in bioengineering. After 
becoming professor emeritus of systems engineering in 1975, he continued to teach 
electrical engineering courses for six years. During the 1940s he worked with J. 
Prosper Eckert EE’41 GEE’43 Hon’64 on improvements to ENIAC; his work improved 
the accuracy of the differential analyzer by inserting an electronic component into an 
otherwise mechanical device.. Later he was involved in projects for private industry 
and the U.S. military, including development of a flight trainer for the Air Force, a 
weapons communication system for the Army, and a navigation system for the Navy. 
During the 1980s he counseled engineers at Stone & Webster, an engineering 
management company in New Jersey. In 1998 the School of Engineering and Applied 
Science introduced an annual student award in his name. His father, also named 
Cornelius Weygandt, had been a professor of English literature at the University and 
an expert on Pennsylvania Dutch life.

Dr. Weygandt, Engineering

 
Dr. Cornelius N. Weygandt, emeritus professor of engineering died on August 8, at the 
age of 99, five days short of his 100th birthday.

Dr. Weygandt was a native of Philadelphia and received his B.S.E.E. degree from 
Penn in 1928, a master's in electrical engineering from MIT in 1933, and his Ph.D. 
from Penn in 1947. He began his career at Penn in 1935 as an instructor in the Moore 
School. He became professor in 1954 and served as Section Head of the 
Instrumentation and Control Section in the Moore School. In 1973 he received a 
secondary appointment in bioengineering. He became emeritus professor of systems 
engineering in 1975. He continued to teach electrical engineering courses for six 
years after his retirement. In 1998 the School of Engineering and Applied Science 
introduced an award in his name to be given annually to a senior whose "qualities and 
potential transcend academic performance alone."

Dr. Weygandt worked with J. Presper Eckert in the 1940s on improvements to ENIAC. 
His work improved the accuracy of the differential analyzer by inserting an electronic 
component into an otherwise mechanical device. Dr. Weygandt also worked at the 
Bockus Research Institute, applying control theory to the cardiovascular system to 
understand the mechanism of blood pressure regulation.

Other projects he worked on included the development of a flight trainer for the Air 
Force, a weapons communication system for the Army, and a navigation system for the 
Navy. 

He is survived by his wife, Marion Christy; daughter, Betty Davies; son, Neil; two 
grandchildren and two great grandchildren.
