Scottish botanist Robert Brown was the first to study this type of motion in 1837. Many of his contributions to science were made possible through the use of a microscope. His work created several experiments, equations, definitions, and examples for the scientific community. He used his microscopes to produce one of the earliest detailed descriptions of the cell nucleus, cytoplasmic streaming, and pollination. Robert Brown created some of the earliest studies of palynology, which is literally the study of dust. His focus on palynology eventually led to his discovery of pedesis which is commonly referred to as Brownian Motion.
