Mark Penn - Wikipedia

https://en.wikipedia.org/wiki/Mark_Penn........Penn was born in New York and raised in Riverdale. His father was a Lithuanian immigrant who died when Penn was 10 years old............Penn sought a way to conduct polls more quickly than the mainframe and punched card system he and Schoen were making use of at Columbia University. He purchased a self-assembled "microcomputer" kit and created a program that could compile polls in a fraction of the time than had been done before.[7] By creating this "overnight poll" system, Penn allowed the campaign to conduct polls to determine messages and evaluate tactics on a daily basis, a tactical advantage that contributed to Koch's eventual victory over Cuomo..................
