Tamara de Lempicka (1898 – 1980) is strongly associated with the Art Deco movement, having risen quickly to recognition during the 1920s and 30s due to her distinctive and bold style of painting. Her style is sometimes referred to as soft cubism (a term coined by André Lhote), her work is more clean and precise than other cubist painters and her use of a brighter colour pallet gives her work a more elegant tone.
I also found out while doing the research for this piece, that in edition to also being the middle child of three, that I shared a birthday with Ms. de Lempicka!
