Albert Levy (soldier)
Bert Yank Levy was a soldier, military instructor and authorpamphleteer of one of the first manuals on guerrilla warfare, which was widely circulated with more than a half million published. He served with irregular forces in several parts of the world in the 1920s and 1930s, most notably in the Spanish Civil War, and was a significant figure at the Osterley Park training school for the British Home Guard during World War II. Similar combat training was provided to forces in the United States and Canada, and he was an itinerant lecturer and provocateur on the subject.
Levy was born in Hamilton, Canada to a Jewish family. His family moved to Buffalo, New York when three months old, and then to Cleveland, Ohio when he was seven years old. His parents were Samuel Levy, a tailor and horse doctor, and Sarah Pollock. Bert Levy had nine siblings. To counter a frail constitution, Levy became a Boy Scout and a boxer. He grew up on the streets and claimed that his real education was in the school of hard knocks. At age 16, he quit school after his father was seriously injured by a trolley. He took employment with the Kaber Printing Company in Cleveland for four years to help support his younger siblings.
