Christina mentions Hughes.  My memory is that Estil also worked at Comsat and Linkabit during the earliest packet-over-satellite and internetworking efforts.  (Linkabit was Jacobs and Viterbi's company before they sold it and founded Qualcomm.)

Hi list,

I'm wondering if anyone has suggestions about a possible (history of computing?) archival home for the papers of Estil Hoversten, who contributed to satellite communications and Internet protocol research (PhD in EE from Iowa State, then faculty at MIT and later in industry at Hughes).  Please email me if you have any thoughts or leads.  

Thank you!
