Patrick Nagel (1945-1984)
Nagel's artwork could arguably be dismissed as not being pinup work. But whatever your feelings on this, I personally feel that his artwork should be in the list. It may not be similar in style to the Vargas and Petty artwork, but it is striking, and his depiction of the female form is such, that not including it here would be something of a travesty.
Born in Dayton Ohio, he first started life in the art world as a freelance artist before beginning work creating graphics for News broadcasts and various other television promotional graphics.
1976 saw him contributing his unique style of feminine images to Playboy, something that may have influenced whoever approached him to create the cover image on Duran Duran's Rio album (the last image shown below being the main cover image of the album).
Nagel eventually became well known for his 'Nagel woman' images, a style of image that relied on being as simple as possible, yet retained enough to still carry the essence of the original picture. Something he did by taking a single photograph and redrawing the image with less and less detail until he was satisfied that sufficient extraneous detail had gone, leaving nothing but the requisite basics.
His artworks have been collected by numerous well known art institutions, and despite his untimely death from a heart attack (he was 38 years old), the fact his artwork is displayed in such prominent locations will ensure his name and artwork will continue to be appreciated by more than just internet browsers.
