Robert Brown
A botanist who discovered the nucleus in plant cells and described Brownian motion, the random movement of particles in a fluid.
Most quoted
"I have, however, been enabled to satisfy myself that the particles or molecules of the pollen of plants, and indeed of many other organic as well as inorganic bodies, when suspended in water, are in a state of constant and rapid oscillatory motion."
— from A Brief Account of Microscopical Observations Made in the Months of June, July, and August, 1827, on the Particles Contained in the Pollen of Plants; and on the General Existence of Active Molecules in Organic and Inorganic Bodies., 1827
"This motion was such as to satisfy me, after frequently repeated observation, that it was not caused either by currents in the fluid, or by its gradual evaporation, but belonged to the particle itself."
