Answer:
Anne Frank's diary which was published posthumously help us remember the holocaust.
Step-by-step explanation:
Anne Frank was one of the million Jews to die in Holocaust by Nazis. But her story reached the people across the world. Anne died at the age of fifteen in the Concentration Camp. Her father, Otto Frank, published her diary, which she used to write in hiding, posthumously in 1947.
It is her diary that helps the readers of her text remember the time of Holocaust. Her diary gives an insight in the life of Jews during the Holocaust. If her father would not have published her diary, people would not have been able to know about how difficult and fretful it was for Jews at the time.
