Erich Ludendorff, the third of six children, was born near Posen on 9th April 1865. His father, August Wilhelm Ludendorff (1833-1905), was a landowner. He was educated at the Cadet School at Plön. An intelligent student he was placed in a class two years ahead of his actual age group.
In 1885 Ludendorff was commissioned as a second lieutenant in the 57th Infantry Regiment. He later served with the 2nd Marine Battalion and the 8th Grenadier Guards. In 1893 he attended the War Academy and the following year was appointed to the General Staff of the German Army. By 1911 he was promoted to the rank of colonel.
Ludendorff worked with General Alfred von Schlieffen on what became known as the Schlieffen Plan. Schlieffen argued that if war took place it was vital that France was speedily defeated. If this happened, Britain and Russia would be unwilling to carry on fighting. Schlieffen calculated that it would take Russia six weeks to organize its large army for an attack on Germany.
