In 2004, he initiated a gathering of all women to serve throughout the years in the Israeli parliament – the Knesset. Preparations to the event led to his initiative documenting the lives and public actions of all female Knesset members. The book showcases the life stories of all women to serve in the Israeli parliament in the years 1949-2011, alongside a historical chapter listing women who served in the Assembly of Representatives during the British Mandate for Palestine.
Over the years of writing his book, Ben-Arie has had personal contact with 70 of Israel's female MKs. His book was published on International Women's Day in 2011 and introduced in a festive sitting of the parliamentary committee on the status of women.
Ben-Arie holds an undergraduate degree in political science, sociology and anthropology from the Hebrew University of Jerusalem and a graduate degree in government and public policy. Ben-Arie lectures in Israel and abroad on women in Israeli politics.
