Little is known about his early life but Franciscus Linus was probably born in London or Buckinghamshire. He died in Liège on 25 November 1675. Linus went to school at the English Jesuit School at St Omer in northern France. In 1623 he entered the Society of Jesus, was ordained priest in 1628 and took his final vows in 1640. Linus became Professor of Mathematics and Hebrew at the English Jesuit College at Liège where he remained for some years. In about 1657 he went on a mission to England, spent time in Derby, London and Lancashire, and returned to Liège in 1672, where he died three years later.
