Reverend Abraham Pierson (1646-1707) was the first rector, from 1701 to 1707, and one of the founders of the Collegiate School — which later became Yale University. He was born in Southampton, Long Island, where his father, the Rev. Abraham Pierson (Sr.), was the pastor of the Puritan (Congregational) church. At that time, Southampton and much of eastern Long Island were administered as part of the Connecticut Colony.
It is commonly stated that Abraham Pierson (Jr.) was born in Lynn, Massachusetts Bay Colony in 1640 or 1641. This claim conflicts with his gravestone in present-day Clinton, Connecticut [see note 5], as well as the period of time he spent as a student at Harvard (1664 to 1668).
Around 1647, Abraham's family moved from Southampton to Branford in what is now Connecticut. At that time, Branford was affiliated with the (unchartered) New Haven Colony. The plans to move from Southampton to Branford began in 1644 when Southampton chose to become affiliated with Connecticut instead of New Haven. Abraham's father was the pastor of the Puritan (Congregational) church in Branford from around 1647 to around 1667. [see note 6]
In 1667, Abraham's family moved to New Jersey where his father established the community of New Ark, present-day Newark, New Jersey. At that time, Abraham (Jr.) was a student at Harvard College. [see note 2]
After graduating from Harvard College in 1668, Abraham was ordained a minister and he joined his father in New Ark. After his father's death in 1678, Abraham succeeded his father as pastor of the First Congregational Church in Newark. Abraham also inherited a library of over 400 books from his father. [see note 7]
In 1691, The Congregational Church in Newark apparently chose to become Presbyterian. At that time, Abraham moved to Greenwich, Connecticut to become the pastor of the First Congregational Church of Greenwich. In 1694, he moved to Killingworth (now Clinton, Connecticut).
Abraham Pierson was the minister of the Killingworth Congregational Church at the same time he started to teach the first classes of what would become Yale University. The new school was supposed to conduct its classes in Saybrook, but the Rev. Pierson could not be relieved of his duties as the pastor in Killingworth. Because of this, the classes were in his parsonage. [see note 8]
Abraham Pierson is today interred in Clinton, Connecticut. Abraham Pierson School in Clinton, Connecticut (grades 4-5) was named for him, and a bronze statue of him is located on East Main Street in Clinton, Connecticut.
