It was FDR, Mr. Roosevelt 10/24/23.

At the risk of sounding like the "well actually"-guy... I know the answer you are looking for is Franklin Roosevelt. However... Although FDR was diagnosed by doctors contemporary to his illness as having polio, retrospective medicine is fairly certain he was misdiagnosed and that he actually had a condition called "acute inflammatory demyelinating polyradiculoneuropathy (AIDP)," which, unlike polio, is not really contagious*. It's a common form of Guillain-Barre syndrome, where some form of infection (could be a number of different virus types) works its way into the peripheral nervous system, but the damage is caused indirectly, as the immune system accidentally attacks the neurons, rather than the virus itself attacking nerve cells as in the case with polio. AIDP was not really at all understood back in the early 20th century, and, even now, is not well diagnosed by modern medicine. (* since the infection can be any number of common virii, which are contagious, but the virus itself does not alone cause the condition, rather only being a trigger for something more likely genetic, I say it's "not a contagious disease," even though the trigger for the condition is a contagion.)
