Norbert Wiener firing of anti-aircraft guns caused Wiener to investigate information theory independently of Claude Shannon and to invent the Wiener filter. (To him is due the now standard practice of modeling an information source as a random process—in other words, as a variety of noise.) His anti-aircraft work eventually led him to formulate cybernetics. After the war, his fame helped MIT to recruit a research team in cognitive science, composed of researchers in neuropsychology and the mathematics and biophysics of the nervous system, including Warren Sturgis McCulloch and Walter Pitts. These men later made pioneering contributions to computer science and artificial
Alexander S. Wiener in numerous investigations by analyzing the blood (or related fluids) of those involved. Numerous articles and chapters of books with real life crime stories were written about Dr. Wiener's work in criminology. Along with his father, George Wiener, a lawyer. Wiener helped draft a new set of laws addressing the recent scientific advancements in blood identification. He was a member of the American Medical Association legal committee that sponsored blood test laws in all states, and he was the co-author of its 1935 report. His work in the genetics of the blood factors also allowed him to be of assistance
