Why Did Zack Polanski Change His Name?
What is Zack Polanski’s real name?
Polanski was born David Paulden in Salford, Greater Manchester. His surname had been anglicised from Polanski, reportedly to avoid antisemitism. He changed his name at age 18 to Zack Polanski. According to multiple sources, the first name “Zack” was partly an homage to a Jewish character from the novel Goodnight Mister Tom.
Why did Zack Polanski change his name?
The name change served two main purposes. First, it was a way to reclaim his Polish Jewish heritage after the original surname Polanski had been anglicised. Second, Polanski has said he wanted to distinguish himself from his stepfather, who was also called David. He told the Big Issue that he did not get on with his stepfather and wanted to avoid being “a little version” of him. The change was formalised by deed poll.
Polanski’s original surname was Polanski, but his family anglicised it to Paulden, likely to reduce antisemitic discrimination. By reverting to Polanski, he consciously reconnected with his Jewish and Polish identity. This decision has been described as both personal and political.
What Is Zack Polanski’s Religion and Recent Controversy?
What is Zack Polanski’s religion?
Multiple reliable sources, including BBC News and Al Jazeera, identify Polanski as Jewish. He has spoken openly about his Jewish faith and the role it plays in his identity. The name change itself was partly a reclamation of that heritage. In a 2025 BBC article, Polanski said: “I won’t accept anyone being excluded from the Green Party because of the religious or communal body they are part.” This statement came after reports of internal party tensions regarding religious inclusion.
A separate controversy involved a voter-registration overlap. Between 2019 and 2021, both his former legal name David Paulden and his new name Zack Polanski appeared on electoral records at the same address. The Green Party explained this was a routine administrative overlap following a deed-poll name change, not an attempt to deceive. The Daily Mail reported the story, but the party’s explanation was included in the same coverage.
A Jewish News outlet claimed Polanski’s former name included “David Theodor Herzl Paulden,” but this report is not corroborated by mainstream sources such as BBC, Wikipedia, or Al Jazeera. It should be treated with caution.
