Portrait of Blaise Pascal (1623 – 1662), French mathematician, physicist, inventor, writer and Catholic philosopher. In honour of his scientific contributions, the name Pascal has been given to the SI unit of pressure and to Pascal's law (an important principle of hydrostatics); Pascal's triangle and Pascal's wager are also named for him. From Alexandre Savérien's 'Histoire des Philosophes modernes', published in eight 4to volumes from 1760-1767. 79 plates (and eight frontispieces) were engraved for the book. The plates engraved for vols 3-8 are adaptated to an in-12mo format, with the addition of a crayon manner border engraved by Jean Charles François (1717 - 1769), inventor of the technique in 1757.
