Studying the reactions and results of introducing French Impressionism into British culture reveals the influence that the city of London had on the development of the movement as it spread internationally. Before Impressionist artists had officially debuted at the Impressionist exhibitions in 1874, their works were on view in London; the artists honed their techniques, using the city as their inspiration. The iconic characteristic of emphasizing the effects of light and air in a composition are seen early on in depictions of the London fog and River Thames. The key meeting between Durand-Ruel and the Impressionist artists while in London affected the movement for its duration. The development of Impressionism as a significant movement is directly related to its initial introduction into the British art market and the attention that it gained from notable art dealers and collectors.
