Who wAS American nurse killed in belgium during ww1?

You are probably thinking of Edith Cavell who was executed by the

Germans on 12 October 1915, however she was English. The US

was not yet in the war at that time and intervened on her behalf,

but to no avail. There was an American-made movie about her and

there are numerous memorials to her and hospitals named after

her around the world in Belgium, France, the UK, Australia, New

Zealand, Canada, the USA and other places.
