Robert Brown

Robert Brown(1773-1858) was born in Montrose, Scotland and took an early interest in botany as a boy. Brown loved to collect plants, and his reputation soon proceeded him. At age 28, Brown accepted an invitation to sail to Australia, where he preceeded to collect over 500 plants in 3 weeks.1

Brown focused much of his energy on the process of fertilization in plants, and chose the cells of Asclepiads and orchids to further his study. In them Brown noticed pollen traveling in and out of ovals in their cells. He termed this oval the "the nucleus".1

Brown first expressed his observations in an 1831 speech, and published them in a paper two years later. His statements suggested the nucleus played a key role in fertilization and development of the embryo in plants. Thus, Brown not only named the nucleus, but created the possibility that it was at the center of cellular creation.
