“You’ve probably never heard of Henry Mandel. Neither had I until I read Without Permission… A machinist who died in New York City in 2015, Mandel was an ardent American Zionist who helped create Israel’s arms industry and challenged Britain’s ban on Jewish immigration to Mandate Palestine. … Without Permission… covers Mandel’s career in workmanlike fashion. Mandel was a rare individual, a man of conviction and action who selflessly devoted himself to a cause higher than himself.”

— Sheldon Kirshner, Times of Israel

"Without Permission is one of those rare achievements that succeeds in twinning painstaking historical research with a compelling personal story. Flaks welcomes the reader into the remarkable life of his grandfather Henry Mandel, a man of courage who served as a Merchant Marine and a volunteer sailor aboard the S.S. Ben Hecht, a ship that sought to challenge the British ban on Jewish emigration to Palestine. Drawing upon eyewitness accounts, oral history and interviews, archival documents, letters and speeches, and significant original research, Flaks' book offers a personal perspective on those complicated moments at the dawn of modern Israel. He demonstrates that Mandel and his fellow crewmen 'struck a significant blow against the British Empire and its imperialist policy of denying the Holocaust survivors of Europe a permanent home and national self-determination.' Joining personal narratives and testimonies with superb historical contextualization, Without Permission is a must-read for anyone interested in the American Jewish experience and the founding of Israel!"
