Medical and research applications of computers were not the only offspring of BBN's early work in time-sharing. The company developed systems for use in business and cocnmerce and for six years operated Telcomp, one of the earliest commercial time-sharing services. These activities formed the basis in 1969 for the award of a contract that was to take BBN into yet another major field of technology--packet-switched data communications--a field in wtnich it has con- tinued to make pioneering efforts of a significant nature. Within one year of the award of this con- tract from the Advanced Research Projects Agency of the Department of Defense. BBN designed, developed, and built a hardware/software system that allowed four geographically separated com- puters of different makes to communicate with each other. The technique used a dynamic routing process in which individual "packets" of data were transmitted over the fastest available routes in tine four-node network, which was interconnected with wide-band telephone lines leased from the Bell System. The dynamic routing process was called packet-switching, and the four-node networt, rap- idly grew into the ARPANET--a network that now includes some 20 computer centers and accom- modates thousands of users daily in the CJnited States, Hawaii and Europe. Ttne network was later expanded to include broadcast satellite channels. ----------------------------------------------------------- [I, division scientist, has a ;Institute, and :\I.S. aId Sc.D. 21 engineerin from .briT.

Some staff members have been with the com- pany since its inception fort years ago, while others have justjoined; all have in common a keen interest in their fields, a commitment to tlaeir work, and an intellectual curiosky that is continually reinforced by the company's strong academic ties. Each year the SDPAmzuul Report profiles a group of 13BN STC scientists to illustrathe dirty aness of our staff. ,.. - '. j:" ''"William Crowther--incipal Engineer ,/.. once wrote in his curriculmn vitae, 'making .... {'' I computers do unexpected things.

Will has been amajor contributor to  k7 the design anti implementation of the  ;}i ARPANET (the Advanced Researci i 2 Projects Agency Network) and BBN s '  Butterfly and Monarch pmallel proces- a :': sots. He x, as mstrmnental m deslgmng the 2 j " Pluribus : multi-processor, the forerunner 5 ' of the Butterfly and the Monarch machines, and contributed to the early design of the SIMNET training system. A mathematician by training, Will uses math to figure out what softv,'are programs will do and how well they ,,viii do it. He says he has always [lad a predilection for pragmatic math -- the kind that "makes things happen," not the theoretical kind used in proofs and theorems. Will first used computers as an undergraduate in MITs playsics department. The physics department had computers; the math department did not, he explains. From MIT, Will went to MIT's Lincoln Laboratory, v,,here he met Frank Heart, now director of the Laboratories Division in BBN STC, and Dave \Valefen, no,.,,' president of BBN STC. His favorite project tilere ,.,.'as the Lincoln Experimental Terminal {LET}, a mobile satellite communications system housed in two trailers. Tile trailers could use virtually any remote object, including the moon, as a surface off which to bornice communi- cations signals. Will designed and implemented tiao software for small computers that aimed the trailers' six-foot dish antennas, made error corrections on the returning signals, and compressed voice signals for digital transmission. ----------------------------------------------------------- ----------------------------------------------------------- ----------------------------------------------------------- -----------------------------------------------------------
