Guillaume Voiriot (20 November 1712 – 9 December 1799[1]) was a French portrait painter.
Voiriot was born in Paris into a family originally from Lorraine; his father was a sculptor.
He travelled to Italy at his own expense from 1746 to 1749, studying at the French Academy in Rome.
Voiriot was a friend of the architect Michel-Barthélemy Hazon; they had travelled to Rome together.
[3] After 1771, he exhibited less often, concentrating on administrative tasks while continuing to paint family members, scientists, writers, actors and musicians.
