Schooten, Francis

, professor of mathematics at Leyden about the middle of the seventeenth century, was a very acute proficient in that science. He published, in 1649, an edition of Descartes’s geometry, with learned and elaborate annotations on that work, as also those of Beaume, Hudde, and Van Heauralt. Schooten published also two very useful and learned works of his own composition; “Principia Matheseos universalis,” 1651, 4to; and “Exercitationes Mathematics,” 1657, 4to. ²
