While Detroit Mayor Edward Jeffries may have initiated the Detroit Plan in the late 1940s, it was his successor Mayor Albert Cobo, 1950-57, (above, pointing) who pile-drived the idea into something tangible. Though regarded as a good mayor by 1950s standards, Cobo definitely set in place a social minefield of problems which would later explode on his successors. Perhaps history has granted him leniency because he died in office. Nevertheless, his failure to address the acute black housing problem may have pleased his constituents, but it was to spell doom for the city in the racial upheaval of the 1960s.
