The experiment they were completing had taken months of preparation. Szilard gave up his work in nuclear physics and joined the Chicago faculty as a professor of biophysics. Szilard died in his sleep of a heart attack on May 30, They invented the chemostata device for regulating the growth rate of the microorganisms in a bioreactor  and developed methods for measuring the growth rate of bacteria.
