Henry "Harry" Hornblower II (1917-1985) was born in Boston, MA, to Ralph and Eleanor Greenwood Hornblower. He received his undergraduate degree from Harvard College in 1941, and went on to work for the successful investment firm founded by his grandfather, Hornblower & Weeks. The Hornblowers had a family estate in Plymouth, MA, and it was there at a young age that Harry became interested in Indian artifacts and archaeology. Hornblower spent his senior year of high school at Phillips Academy (Class of 1937), to take advantage of the opportunities offered by the Department of Archaeology (Robert S. Peabody Foundation for Archaeology; Robert S. Peabody Museum of Archaeology) and study with Douglas Byers and Frederick Johnson. He also spent a semester at the University of California, Berkeley, as an undergraduate, participating in excavations in the Southwestern United States and Mexico. Hornblower went on to found the Plimouth Plantation, a historic reconstruction of the 17th century Plymouth colony in Massachusetts. He was married to Dorothy Shapard, and later to Malabar Schletter, and had four children: Henry Hornblower III, Augusta, Harriet and Eleanor.
