B. H. Liddell Hart

Sir Basil Henry Liddell Hart (31 October 1895 – 29 January 1970), commonly known throughout most of his career as Captain B. H. Liddell Hart, was an English soldier, military historian and military theorist. He is often credited with greatly influencing the development of armoured warfare, although some research casts some doubt on the extent of his influence upon the pre-war German military.
