Gilbert Clerke was born in Uppingham, Rutlandshire. The son of a schoolmaster, he was admitted to Sidney Sussex College, Cambridge in 1641. He graduated BA in 1645, and MA in 1648, becoming a Fellow of his College from 1648 until 1655. He received a Presbyterian ordination in 1651, but quit his Fellowship and the University in 1655 because his religious scruples would not permit him to take the degree of Bachelor of Divinity. He inherited a small property at Luffingham, near Stamford in Northamptonshire, where he was to reside for the rest of his life, living on his modest income and contenting himself with a scholarly life devoted to mathematics, natural philosophy and theology.
