I am looking for information on Detroit 100 years ago [[1914 - ie, during World War One).

I am also looking for information on Detroit's war effort during World War Two, as well.

Specifically, what changes happened to Detroit's manufacturing during those times - such as switches away from automobile manufacturing towards armaments manufacturing to help with the war effort?

I think Detroit's industrial capacity was put to good use during the two world wars. Maybe that aspect of Detroit's history has been overlooked or under-appreciated?

Opinions welcome... thanks!
