The 3rd Marquess of Exeter (1825-1895) was an eminent pisciculturalist and a very successful breeder of dairy shorthorn cattle.
He won many national awards for individual animals, for family groups and for his herd in general.
The artist was sometimes known as Henry Weigall Jnr., to distinguish him from his father Henry, a sculptor, gem engraver and modeller.
Weigall, who specialised in portraiture, had a long and successful career, painting members of the Royal Family, famous political figures and members of the aristocracy.
He exhibited at the Royal Academy on several occasions.
