Kudos to your father. I went to a vocational school in Pontiac, Michigan. Paid for and funded by General Motors to encourage youth to persue technical careers in manufacturing. That was in the late 1980’s.
Those programs are no more.
He had graduated from a similar engineering program at the University of Cincinnati, so it was a good fit for him. He also was employed throughout the depression! The school changed a lot while he was there. The Detroit ‘67 riot started just down the street from the school. Fortunately, that happened during summer vacation. The original building was closed a while ago, and the school in now known as Murray-Wright and is located a few blocks away.
