My great uncle, Burton L. Watt, worked for Lake Shore Engine Works in Marquette, Michigan for most of his life. My dad tells a story about Uncle Burt's work in his autobiography.
"Uncle Burt, upon graduation from high school in Marquette, started to work at Lake Shore Engine Works. Eventually, he came to be Vice-President of the company and although they had no retirement pensions, as such, the President of the company saw to it that he received a monthly check, which he received right up to his death at the age of 101, even though the company management changed hands several times."
Lake Shore Engine Works, which was later Lake Shore Iron Works and other names, was built in 1890. It used to manufacture mining, milling, and general machinery.
