(p. B15) Leo L. Beranek, an engineer whose company designed the acoustics for the United Nations and concert halls at Lincoln Center and Tanglewood, then built the direct precursor to the internet under contract to the Defense Department, died on Oct. 10  at his home in Westwood, Mass.
. . .
After the war, Dr. Beranek was recruited to teach at M.I.T., where he was named technical director of the engineering department’s acoustics laboratory. The administrative director of that lab was Richard Bolt, who later founded Bolt, Beranek & Newman with Dr. Beranek and Robert Newman, a former student of Dr. Bolt’s.
The company was conceived as a center for leading-edge acoustic research. But Dr. Beranek changed its direction in the 1950s to include a focus on the nascent computer age.
“As president, I decided to take B.B.N. into the field of man-machine systems because I felt acoustics was a limited field and no one seemed to be offering consulting services in that area,” Dr. Beranek said in a 2012 interview for this obituary.
He hired J.C.R. Licklider, a pioneering computer scientist from M.I.T., to lead the effort, and it was Dr. Licklider who persuaded him that the company needed to get involved in computers.
Under Dr. Licklider, the company developed one of the best software research groups in the country and won many critical projects with the Department of Defense, NASA, the National Institutes of Health and other government agencies. Though Dr. Licklider left in 1962, the company became a favored destination for a new generation of software developers and was often referred to as the third university in Cambridge.
“We bought our first digital computer from Digital Equipment Corporation, and with it we were able to attract some of the best minds from M.I.T. and Harvard, and this led to the ARPA contract to build the Arpanet,” Dr. Beranek said.
“I never dreamed the internet would come into such widespread use, because the first users of the Arpanet were large mainframe computer owners,” he said. “This all changed when the personal computer became available. With the PC, I could see that computers were fun, and that is the real reason why all innovations come into widespread use.”
