John Singer Sargent

 I love, love, love John Singer Sargent's portraits.

John Singer Sargent (January 12, 1856 – April 14, 1925) was the most successful portrait painter of his era, as well as a gifted landscape painter and watercolorist. Sargent was born in Florence, Italy to American parents. 

Sargent studied with Carolus-Duran, whose influence would be pivotal, from 1874-1878. Carolus-Duran's atelier was progressive, dispensing with the traditional academic approach which required careful drawing and underpainting, in favor of the alla prima method of working directly on the canvas with a loaded brush, derived from Diego Velázquez. It was an approach which relied on the proper placement of tones of paint.
