Pederson was born in Hallock, Minnesota to Oscar Jorgan and Beda Emilia Pederson. He attended Fergus Falls Public Schools in Fergus Falls, Minnesota during which time he built his first crystal radio by using junkyard finds and spare parts which were given by his uncle and cousin. During those years he also saved money, and eventually bought his first soldering iron and a vacuum tube. Don's passion for electronics began in high school during physics class in Fargo, North Dakota where his parents had moved. He graduated high school at age 17 and entered Iowa State College in the autumn of 1943, but then left for the military during World War II. He served as a private in the U.S. Army in Austria, Germany, France and the Philippines from 1943 to 1946.[1]
Pederson remained at Stanford as a researcher in the university's electronics research lab. From 1953 to 1955, he worked at Bell Telephone Laboratories, in Murray Hill, New Jersey, and lectured at Newark College of Engineering (now New Jersey Institute of Technology). In 1955, Pederson joined the faculty of the Department of Electrical Engineering and Computer Sciences of the University of California, Berkeley as an assistant professor of electrical engineering. In the early 1970s he began work on SPICE, with his colleagues from the Electronic Research Lab.[1] He retired in 1991, but continued to teach part-time.[2]
Don was married to Claire N. Pederson and together they had three daughters (Emily Sanders, Margaret Stanfield, and Katharine Rookard) and a son (John). They also had four grandchildren
