Der Purim-ber is a play for children in three acts by “Der Tunkeler”, published in Odessa in 1919. The 34-page long play tells the story about little Yosele, the rabbi’s son, who meets a talking bear in the forest.

“Der Tunkeler” (The Dark One) was a pen name used by the well-known Yiddish writer of poetry and humorous prose, Yosef Tunkel (1881–1949). Born in Belarus to a poor family, Tunkel was a sickly child with a gift for drawing. The community sponsored his education at a Vilnius art school, and Tunkel went on to travel to America, where he founded the Der kibitzer - later Der Groyser Kundes -, perhaps the most significant Yiddish humor magazine of all time.
