Twin Cities hospitals were packed and Minnesota kids cooped up in the summer of 1946. Not only were swimming pools and movie theaters closed, the Minnesota State Fair locked its gates during the state's deadliest polio outbreak — nearly 3,000 cases that resulted in 226 deaths.
Polio struck children especially hard in 1946. More than 70% of Minnesota's cases and half the state's deaths hit those under 15. Spreading mostly in the summer months, the polio virus festered in lakes and pools and attacked the brain, spinal cord and muscles. Often too weak to breathe, some patients were locked in iron lung machines that kept them alive with only their heads exposed.
"The disease struck suddenly and without warning," a state Health Department report said, "leaving visible reminders: paralysis, wheel chairs and leg braces."
This was before the advent of TV, let alone Zoom platforms and social media. At the peak of the crisis KUOM, the radio station at the University of Minnesota, jumped into the void to lighten quarantined kids' burden.
"Parents grew weary as their children, lacking entertainment and activity, became agitated while stuck indoors during summer vacation," Rebecca Toov, a U archivist, wrote in a 2016 web post on KUOM's service in the 1946 epidemic.
The roots of KUOM date to 1922, when its precursor received the state's first broadcast license, becoming one of the nation's first radio stations. Today, after a merger with another campus station, KUOM is known as an alternative music station called Radio K.
But during nearly seven summer weeks in 1946, the radio station devoted more than 150 hours to children's programs, roughly one-third of its schedule. Civic groups, listeners and even other radio stations kicked in funding and on-air talent.
"It constituted ... a not-often-equaled example of cooperation between an educational radio station and the community it serves," wrote Burton Paulu, KUOM's station manager at the time.
