Crumstone Irma, aka Irma, was an Alsatian who assisted in the rescue of 191 people trapped under blitzed buildings while serving with London's Civil Defence Services during the Second World War. During this period she worked with her handler and owner, Mrs Margaret Griffin, and another dog named Psyche. Noted for her ability to tell if buried victims were dead or alive, she was awarded the Dickin Medal in 1945, and is buried at the PDSA Animal Cemetery, Ilford.
