Like most art museums in large cities the Detroit Institute of Arts was started by a few local citizens. Major contributors of money and art included the Dodges, Firestones, Fords, and Scripps. The wealth generated by the auto industry allowed them to amass a large and amazing collection creating a museum with over 100 galleries and 66,000 works of art. We visited for four hours and only saw half of it!
The museum is accessible.
