War invalids
No other war left such an army of invalids and men with diseases and life-long psychological scars. Mechanical aids such as this writing aid were designed to restore functions to those wounded in the war and in this way to help them to reintegrate into the labour market. Even several years after the end of the war, it was impossible to determine the number of people who had returned injured or diseased from the front. In 1922 there were around 143,000 war invalids living in Austria.
