Life of Monsieur Pascal
Gilberte Périer
The short life of Blaise Pascal written by his elder sister Gilberte Périer. It is the family’s own account and gives the days of his birth and death.
Gilberte Périer writes as a sister and an admirer, and her aim is to show her brother’s piety. She begins with his birth at Clermont on 19 June 1623 and ends with his death on 19 August 1662, at the age, she says, of thirty-nine years and two months. The wiki cites her for those dates.
