Computers and those professionals that preserve, troubleshoot, program, administer, community, and build them are central to most every business. An inspiring summer faculty on computing at the University of Pennsylvania´s Moore Faculty of Electrical Engineering stimulates development of saved-program computers at universities and research establishments in the US, France, the UK, and Germany. Among the lecturers were early laptop designers like John von Neumann, Howard Aiken, J. Presper Eckert and John Mauchly, in addition to mathematicians including Derrick Lehmer, George Stibitz, and Douglas Hartree. Students included future computing pioneers comparable to Maurice Wilkes, Claude Shannon, David Rees, and Jay Forrester. This free, public set of lectures impressed the EDSAC, BINAC, and, later, IAS machine clones just like the AVIDAC.
