1778 Phillips Academy is founded
Samuel Phillips Jr and his friend and fellow Harvard College graduate Eliaphet Pearson, with whom he founded the gunpowder mill, dreamed of starting a school to preserve and promote piety in the face of what they saw as degeneracy, ignorance, vice, disorder, and wickedness.
In April 1778, at 26 years old, Phillips Jr. and Pearson drew up the constitution for Phillips Academy, opening the school to all qualified boys.
In 1973 Phillips Academy merged with neighboring Abbot Academy, which was founded in 1829 as one of the first schools for girls in New England.
