Paul Baran Oral History

Baran received his BS in electrical engineering from the Drexel Institute of Technology (now Drexel University) in 1949.  He worked for the Eckert Mauchly Computer Company on the UNIVAC, 1949-50, Raymond Rosen Engineering Products on magnetic taper error correction and the Cape Canaveral telemetering system, 1950-53, and Hughes Aircraft on radar data processing,1955-59.  He took classes at UCLA, 1955-62, and got an MS in engineering in 1959.  He worked on missile command and control from the laste 1950s.  He went to the RAND Corporation as a researcher, 1959-68, working on defense against a nuclear first strike—particularly, working on communication, how to get messages through after a military strike.  Working on high data rate distributed communications in early 1960s, digital redundant means for military to communicate even after a nuclear first strike ; e.g., packet switching.  He later worked on gun detection, computer privacy, and then helped set up the ARPANET.  He then  went to work for the Institute for the Future, working on quality control.  From 1973 he went to work at Cabledata Associates, recommending divestiture of the ARPANET (though not carried out for a while); working on low cost computer printers, satellite transponders, telephone modems, packet technologies, remote electric metering, automated response to faxes, and ATM-Cable TV combinations.
