Robert Gribbroek (March 16, 1906 – October 13, 1971) was a layout artist and background painter at the Warner Bros. Cartoons from 1945 until 1964.
[1] Following a three-year absence, Gribbroek re-emerged in 1953, initially installed within his previous position as Jones' layout man.
Gribbroek was reallocated, however, to Robert McKimson's then-recently reopened unit in 1954, in which he would remain until the studio's closure in 1963.
His last original credited work was as a layout artist on the 1966 Spanish animated feature El mago de los sueños (though Gribbroek would be credited on later Warner compilation specials/features, for his work on the classic Warner cartoons).
Gribbroek was not a highly celebrated artist during his career, but many cartoon fans have since come to admire his work.
