Gideon studied law at the University of Warwick where he became heavily involved in Jewish causes as President of the Jewish Society. He was elected Anti-Racism Officer for the student body and appointed to advise the two police forces on hate crime. He graduated and returned to London in 2005.
Gideon joined the nascent Campaign Against Antisemitism in the summer of 2014, as fighting flared between Hamas and Israel and antisemitism surged in Britain. He was the principal organiser of Campaign Against Antisemitism’s major rally outside the Royal Courts of Justice which called for zero tolerance law enforcement against antisemitism. Gideon was elected to lead Campaign Against Antisemitism in autumn 2014.
Gideon has spoken at the House of Commons and given evidence to the House of Commons Home Affairs Committee. His work for Campaign Against Antisemitism has been publicly praised by Theresa May.
The Algemeiner awarded Gideon as one of the “top 100 people positively influencing Jewish life”, and the Simon Wiesenthal Center hailed him as a “Jewish hero who proves that there are still powerful ways to leverage democratic rules to serve justice and protect Jewish community”.
Gideon has worked in high-tech, commercial real estate and management consultancy. In addition to his charitable work for Campaign Against Antisemitism, he also serves as a Board member of the Jewish National Fund UK.
