Money and power, in brief

One line each, as scoped

The lead bank: The banking system of South Bend is the Banks leg's record, and this section carries only the business line: the bank founded in 1863 as the First National Bank of South Bend — renamed 1st Source Bank in 1981, headquartered at 100 North Michigan Street — is, on its corporation's own account, the largest locally controlled financial institution headquartered in the northern Indiana and southwestern Michigan area, and it stands in the downtown its depositors' factories built.

The power line: The city's electricity ran, in the early industrial years, off the river itself: the Oliver works' West Race water-power property passed in the late 1940s to the Indiana & Michigan Electric Company, the utility that gathered up the races' power rights, and the city's electric utility today is Indiana Michigan Power, an American Electric Power company — the corporate line in one sentence, as the public record carries it.
