Nehemiah Grew

Baptized 26 Sep 1641; died 25 Mar 1712 at age 70. English botanist, physician, and microscopist, who was one of the founders of the science of plant anatomy. He began observations on the anatomy of plants in 1664, and his first essay on the subject, The Anatomy of Vegetables Begun was presented to the Royal Society of London in 1670 (published 1672). He took a particular interest in determining the physiological nature of the tissues. He observed the pourous structure of plant tissue, suggested that flowers have a sexual function, and was first to use the term "comparative anatomy" (1676, in a lecture at the Royal Society). His extensive studies of plant tissues, including roots, trunks, leaves, flowers, fruits and seeds were published in a major work The Anatomy of Plants (1682). From a chemical analysis of water from springs at Epsom, Surrey, he isolated magnesium sulphate, which remains known as "Epsom Salts."
