It seems hard to believe these days, but impressionists such as Claude Monet were once reviled by critics and their paintings were impossible to sell.
But one art dealer, Paul Durand-Ruel, championed the likes of Monet, Renoir and Pissarro for decades, ultimately transforming artistic taste in Europe and the United States.
"Without Durand, we would have died of hunger, all of us impressionists," Monet is quoted as saying.
"We owe him everything."
"He was stubborn and relentless, risking bankruptcy a dozen times in order to support us."
At Geelong Gallery, Discovering the Impressionists: Paul Durand-Ruel, Art Dealer Among the Artists, features more than 70 paintings, the majority from private collections in France.
With eight artworks by Monet, the show marks the centenary of the painter's death, as well as Geelong Gallery's 130th anniversary.
