Agnes Richter was a German seamstress held as a patient in an insane asylum during the 1890s. During her time there, she densely embroidered her straightjacket with words, undecipherable phrases and drawings which  documented her thoughts and feelings throughout her time there. This remarkable object was collected by Hans Prinzhorn, a psychiatrist who ardently collected the artwork of his patients at a Heidelberg psychiatric hospital in the early 20th century.
