A photographic memorial by Sarah Ketelaars

Artist Sarah Ketelaars created 544 cyanotypes as a memorial to 544 psychiatric patients murdered by the Nazis in 1941 in Latvia. Each cyanotype represents a man, woman or child killed.

Sarah writes: 'My grandmother was working at the hospital from where the patients were taken. I have visited the hospital and found that although the story is known no memorial exists. The only official record seems to be a short paragraph in the Nuremberg report. So far I have found no record of the names.

It is impossible for me to look at these images without thinking about how the lives of these people ended. However, the project is primarily intended as a memorial. I wanted the images to hint at some more celebratory moments, to remember the lives lived before these people entered the hospital; before they died. Not knowing anything about the the identities of the dead, I have tried to imagine each one as a unique, precious being, and give each back a little of the character stripped from them when they were murdered and reduced by history to a number on a list of nameless victims.'
