Just for the record, it WAS called the Michigan Asylum for the Insane (see below):

"First known as the Michigan Asylum for the Insane, it became the Kalamazoo State Hospital in 1911. On the first of January 1978, the name changed to the Kalamazoo Regional Psychiatric Hospital. In July 1995, it assumed its present designation, the Kalamazoo Psychiatric Hospital, although most local residents still commonly refer to it simply as "the State Hospital."
