He held professional positions including member of the National Academy of Engineering (since 1982) and President of the American Geophysical Union from 1986-1988.
Peter was born in 1928 in Philadelphia to Helen (née Sturges) and William Boal Eagleson and attended Lehigh University in Bethlehem, Pennsylvania.
