Nehemiah Grew
He mapped the hidden architecture of plants, revealing their intricate inner structures for the first time and founding the science of plant anatomy.
1641–1712 (age 71)·English plant anatomist and physiologist·Birthday: September 26
Biography
Born in Warwickshire, Nehemiah Grew pursued medicine at Cambridge and Leiden, but his true legacy sprouted from a different passion. While practicing as a physician, he turned his meticulous, dissecting eye to the flora around him. In the late 17th century, armed with a microscope, Grew embarked on a systematic study of plant tissues, producing detailed illustrations of stems, roots, and seeds. His work, compiled in volumes like 'The Anatomy of Plants,' presented a revolutionary vision: plants were not simple, formless things but complex organisms with specialized parts, comparable in organization to animal bodies. He described cells (calling them 'vesicles' or 'bladders'), identified sexual reproduction in plants, and analyzed the function of pollen. This rigorous, empirical approach shifted botany from mere classification to a study of internal function and form, establishing a foundational discipline that would feed into future discoveries in biology and agriculture.

Key Achievements
- Published the seminal work 'The Anatomy of Plants' in 1682, which systematically detailed the internal structure of vegetation.
- Is widely credited as a principal founder of the scientific field of plant anatomy through his microscopic investigations.
- Made pioneering observations of plant sexuality, including the role of pollen in fertilization.
- Served as a Secretary to the Royal Society, where he helped disseminate major scientific works of his era.
Did You Know?
He initially studied and earned a medical degree, and his botanical work was conducted parallel to his career as a physician.
Grew was a contemporary of Marcello Malpighi, another pioneer of plant anatomy; their work was often published concurrently by the Royal Society.
He conducted early experiments on plant nutrition, suggesting plants absorbed substances from both air and soil.
His father, Obadiah Grew, was a prominent Nonconformist minister.
“The fabric of a leaf is a text of exquisite geometry, written by nature's own hand.”
