Born in Englewood, New Jersey, Muir received a Bachelor of Arts degree from Lehigh University in 1935 and a Bachelor of Laws from Harvard Law School in 1938. He was in private practice in Williamsport, Pennsylvania, from 1938 to 1942. He served in the United States Navy during World War II, from 1942 to 1945, achieving the rank of lieutenant. Afterwards he returned to private practice in Williamsport until 1970.
