In 1943 I was a second-year medical student in Kansas City, enrolled in an accelerated program designed to finish the four-year course in three years. We had little or no time for recreation, but, thanks to a scheduling quirk, those in my section of the class suddenly found ourselves with two open weeks. I seized the opportunity to gain a bit of practical experience by accompanying some physician mentors on their rounds at a hospital back home in Wichita.
One of these doctors had admitted a patient with subacute bacterial endocarditis (an infection of the inside lining of the heart), who was doing very badly. Back then there was no treatment for this disease, and most hospitals had little to offer except supportive therapy: giving the patient fluids and trying to prevent bedsores.
