Check out just some of the papers on the program that deal with disability (and there are surely others, but these titles stuck out for me):
Sandy McFarlane and Keith Horsley, "Florence Nightingale: A Sufferer of a Post-Deployment Syndrome"
Margaret Goldswain, "The War-Damaged Soldier in Australia after the Great War"
Melanie Oppenheimer, "'Fated to a life of suffering': Graythwaite, the Australian Red Cross, and Returned Soldiers, 1916-1939"
Keith Horsley and Sandy McFarlane, "Post-Deployment Syndromes Following Wars in the Nineteenth and Early Twentieth Centuries"
Kristy Muir, "'There were no ticker tape parades for us': Homecomings of Veterans with Mental Health Problems"
Jim Porteous, "Rehabilitation of Injured or Ill Australian Defence Force Members"
Jen Hawksley, "Histories from the Asylum: 'The Unknown Patient'"
Kerry Neale, "'Without the Faces of Men': The Return of Facially Disfigured Australian Veterans from the Great War"
Marina Larsson, "'The Part We Do Not See': Disabled Australian Soldiers and Family Caregiving after World War I"
Stephen Clarke, "The Long Shadow of War: The New Zealand Experience of 'Burnt-Out Diggers' during the 1920s and 1930s"
Curious to learn more about any of these projects? The program (linked above) includes abstracts for all of them.
Illustration above: a stamp that promotes Esperanto as a way to end war, with a simple illustration in green of a uniformed man on crutches; from the 1920s, I think? (Lost the cite. Bad historian.)
