Francis Bacon (28 October 1909 – 28 April 1992) was an Irish-born British figurative painter known for his bold, grotesque, emotionally charged, raw imagery. He is best known for his depictions of popes, crucifixions and portraits of close friends. His abstracted figures are typically isolated in geometrical cage like spaces, set against flat, nondescript backgrounds. Bacon said that he saw images "in series", and his work typically focuses on a single subject for sustained periods, often in triptych or diptych formats. His output can be broadly described as sequences or variations on a single motif; beginning with the 1930s Picasso-informed Furies, moving on to the 1940s male heads isolated in rooms or geometric structures, the 1950s screaming popes, and the mid-to-late 1950s animals and lone figures, the 1960s portraits of friends, the nihilistic 1970s self-portraits, and the cooler more technical 1980s late works.

Bacon took up painting in his late 30s, having drifted as an interior decorator, bon vivant and gambler. He said that his artistic career was delayed because he spent too long looking for subject matter that could sustain his interest. His breakthrough came with the 1944 triptych Three Studies for Figures at the Base of a Crucifixion, which sealed his reputation as a uniquely bleak chronicler of the human condition. From the mid-1960s he mainly produced portraits of friends and drinking companions, either as single or triptych panels. Following the 1971 suicide of his lover George Dyer, his art became more sombre, inward-looking and preoccupied with the passage of time and death. The climax of this later period is marked by masterpieces, including his 1982's "Study for Self-Portrait" and Study for a Self-Portrait—Triptych, 1985–86.
