Jan Ingenhousz had described the irregular motion of coal dust particles on the surface of alcohol in 1785 — nevertheless the discovery is often credited to the botanist Robert Brown in 1827.
In the 1770s Ingenhousz became interested in gaseous exchanges of plants prior to reading about the work of scientist Joseph Priestley (1733–1804),who found out that plants make and absorb gases.
