Giovanni Boldini (31 December 1842 – 11 July 1931) was an Italian genre and portrait painter, belonging to the School Of Paris. According to a 1933 article in Time magazine, he was known as the "Master of Swish" because of his flowing style of painting.
Boldini attained great success in London as a portraitist. From 1872 he lived in Paris, where he became a friend of Edgar Degas. He also became the most fashionable portrait painter in Paris in the late 19th century, with a dashing style of painting which shows some Impressionist influence but which most closely resembles the work of his contemporaries John Singer Sargent and Paul Helleu. He was nominated commissioner of the Italian section of the Paris Exposition in 1889, and received the Légion d'honneur for this appointment.
