The graphic novel “The Invisible War: A Tale on Two Scales” tells stories of the macroscopic (nurses) and microscopic (bacteriophage) heroes fighting dysentery at the Western Front of World War I. Interweaving Views of Tales, Scales, and Heroes “The Invisible War: A Tale of Two Scales” works its magic, interweaving the stories of two rarely discussed topics – dysentery and bacteriophage – and two rarely intertwined fields of study – science and history. The resulting story is a rich tapestry full of action and information at both the macroscopic and microscopic levels. “The Invisible War” tells about Annie, a nurse at a field hospital at the Western Front of World War I. In her nursing experience, Annie has learned the symptoms and consequences of dysentery, at a time when the cause wasn’t well understood and no reliable cure was known.
