Robert Brown, 1773-1858 |
Our chairman Ian Denholm has been corresponding with Miss M.F.
Brown of Kingston, Surrey, who is a cousin, four generations removed, of the famous
Scottish polymath Robert Brown.
Although born 36 years before Charles Darwin, in
later life these two illustrious biologists would have overlapped and there are
interesting parallels in events that shaped their scientific achievements. After
formal training in medicine and a period of military service, Robert was
appointed as resident naturalist aboard a ship `The Investigator’ for a voyage
circumnavigating Australia.
Partly through
having Sir Joseph Banks as a mentor, he focused his attention on plants and at
least 2,000 of the species he collected proved to be new to science. Consequently a number of Australian species
bear the epithet brownii and he is also recognised through the genus Brunonia
(Goodeniaceae) – the Australian blue pincushion flower.
Back from his travels, Robert Brown pioneered many aspects of
microscopy and coined the term “nucleus” for one of the most distinctive
intracellular organelles. He was the
first to describe the behaviour of particles (initially by observing pollen
grains) that is now universally known as Brownian motion.
In 1988, Miss Brown wrote an article on Robert in `The
Linnean’, and this is now freely accessible through the archives of the Linnean
Society. This link takes you to the start of Volume 4 and the piece on Robert Brown
starts on page 38.
Miss Brown also
recalls with delight a recent visit to Kew to inspect the original microscopy
equipment used by the great man himself (see photo on left)!
