Potash (Potasch) Oleg Grigorievich (7 August 1947, Riga) — watchmaker.

At the age of nine months, Oleg Potash contracted poliomyelitis and was subsequently granted a Category II disability status. In 1961, he completed seven grades at Secondary School No. 23 but, on medical advice, discontinued his studies. Due to family circumstances, including the illness of his father, Girsh Potash (1909), and his mother, Frida Potash (née Blaer) (1921), he began working as a watchmaker in 1961. In 1964, he completed the eighth grade at an evening school.

In the 1960s, together with his parents, Oleg Potasch petitioned for permission to emigrate to Israel for permanent residence in order to join his father’s relatives.
