Vynokur Yakiv Yosypovych was born in Kyiv. Before marrying Anna Aleksandrivna Semenova, he lived with his parents – Joseph Vynokur, Golda Vynokur and his sister Masiia Vynokur.
He was married with two children – Inna Yakivna Vynokur (born in 1941) and Larysa Yakivna Vynokur (born in 1935).
He worked before his arrest.
In September, when the Germans announced to all Jews to come to Babyn Yar at that time, he went there with his wife and children. On Melnikova Street they met their parents and sister. A German soldier did not let his wife and children go there, so they said goodbye and Yakiv, his family and other Jews went on, and his wife and children returned home. They had never seen each other again.
