Magic Lantern Slide portrait of General Kitchener

Horatio Herbert Kitchener (1850-1916) was a British Field Marshal and colonial administrator who played a key role in World War I.
He was born in Ireland and trained as a military engineer. He served in the Middle East and Egypt, and became commander-in-chief of the Egyptian army in 1892.
He served as chief of staff in the Second Boer War, and later became Commander-in-Chief.
Kitchener became Secretary of State for War at the start of World War One. He oversaw the rapid expansion of the British Army through the recruitment of volunteers. He became the face of the First World War when he appeared on the 'Your Country Needs You' poster.
He died in 1916 when his ship, HMS Hampshire, struck a German mine while en route to Russia on a diplomatic mission. He was the highest ranking officer to be killed during the war.

According to 'Victorian Collections', lantern slides, sometimes called 'magic lantern' slides, are glass plates on which an image has been secured for the purpose of projection. Glass slides were etched or hand-painted for this purpose from the Eighteenth Century but the process became more popular and accessible to the public with the development of photographic-emulsion slides used with a 'Magic Lantern' device in the mid-Nineteenth Century.
Photographic lantern slides comprise a double-negative emulsion layer (forming a positive image) between thin glass plates that are bound together. A number of processes existed to form and bind the emulsion layer to the base plate, including the albumen, wet plate collodion, gelatine dry plate and Woodburytype techniques. Lantern slides and magic lantern technologies are seen as foundational precursors to the development of modern photography and film-making techniques.
