Council of Heads of Australasian Herbaria
Westall was born in Hertford, England.
He joined the Investigator as landscape artist on Matthew Flinders' expedition to Australia in 1801. During the voyage, he made many pencil-and-wash landscapes and a series of pencil coastal profiles. Some years later, he was commissioned to paint nine pictures for Flinders' A Voyage to Terra Australis (1814).
