On 2 September 1944, Bella died suddenly due to a virus infection, which was not treated due to the wartime shortage of medicine. As a result, he stopped all work for many months, and when he did resume painting his first pictures were concerned with preserving Bella's memory. Wullschlager writes of the effect on Chagall: "As news poured in through 1945 of the ongoing Holocaust at Nazi concentration camps, Bella took her place in Chagall's mind with the millions of Jewish victims." He even considered the possibility that their "exile from Europe had sapped her will to live."
