Lisette Denison's Land & Polio Vaccine | Apr 12

On this day in 1825, we remember Lisette Denison, the first Black woman landowner in Michigan, who bought 48.5 acres in Pontiac in 1825. We also highlight the 1955 announcement of the polio vaccine's success by the University of Michigan. Additionally, in 2016, Michigan State University took a significant step to combat climate change by ceasing coal burning in their power plants.
