Isaac Beeckman (10 December 1588 – 19 May 1637) was a Dutch philosopher and scientist, who, through his studies and contact with leading natural philosophers, may have "virtually given birth to modern atomism". Biography Beeckman was born in Middelburg, Zeeland, to a strongly Calvinistic family, which had fled from the Spanish-controlled Southern Netherlands a few years before. He had a strong early education in his home town and went on to study theology, literature and mathematics in Leiden. Upon his return to Middelburg he could not find a position as a minister, due to clashing ideas of his father and the local church, and decided to follow his father in the candle-making business, setting up his own company in Zierikzee. While trying to improve on the candle-making process, he also involved himself in other projects, like creating water conduits and doing meteorological observations. In 1616 he sold the business to his apprentice and went to study medicine in Caen, where he graduated in 1618. On his return, he became an assistant rector in Utrecht. On April 1620 he married Cateline de Cerf, whom he knew from Middelburg, and with whom he would have seven children. From 1620 to 1627 he taught at the Latin school in Rotterdam, where he founded a "Collegium Mechanicum", or Technical College. From 1627 until his death at the age of 48 he was rector of the Latin school in Dordrecht. Teachers, pupils, and Descartes Beeckman's most influential teachers in Leiden probably were Rudolph Snellius and Simon Stevin. He himself was a teacher to Johan de Witt and a teacher and friend of René Descartes. Beeckman had met the young Descartes in November 1618 in Breda, where Beeckman then lived and Descartes was then garrisoned as a soldier. It is said that they met when both were looking at a placard that was set up in the Breda marketplace, detailing a mathematical problem to be solved. Descartes asked Beeckman to translate the problem from Dutch to French. In their following meetings Beeckman interested Descartes in his corpuscularian approach to mechanical theory, and convinced him to devote his studies to a mathematical approach to nature. In 1619, Descartes dedicated one of his first tractati to him, the Compendium Musicae. When Descartes returned to the Dutch Republic in the autumn of 1628, Beeckman also introduced him to many of Galileo's ideas. In 1629 they fell out over a
