Ballistic Research Laboratory
The Ballistic Research Laboratory (BRL) at Aberdeen Proving Ground, Maryland was the center for the United States Army's research efforts in ballistics (interior, exterior, and terminal) as well as vulnerability/lethality analysis.
In 1992, the BRL's mission, personnel, and facilities were incorporated into the newly created Army Research Laboratory, and BRL was disestablished.
History
According to a pamphlet published in 1955 by the US Army's Ordnance Corps, BRL was "established by the Ordnance Department (Ordnance Corps) because they recognized that Ballistics, the study of the motion of projectiles, provides a rational foundation for the design and development of Ordnance."[1] The name was originally plural, reflecting subordinate laboratories for each of the ballistic disciplines, but these were eventually redesignated divisions of a single laboratory.
Advisors and Consultants
Over the years, and particularly during World War II, BRL's permanent technical staff was augmented by a number of eminent scientists and engineers serving in various capacities.[1] Chief among these was the Scientific Advisory Committee (SAC). Established in 1940, the SAC included such members as
Hugh Dryden the first director of NASA Joseph E. Mayer chemist and eventual president of the American Physical Society Clark Millikan professor of aeronautics at the California Institute of Technology and founding member of the National Academy of Engineering I. I. Rabi Nobel laureate and discoverer of nuclear magnetic resonance, and John von Neumann mathematician, physicist, and founding figure in computing .
Other consultants included astronomer Dorrit Hoffleit; chemists John Gamble Kirkwood (recipient of the Langmuir Award), George Kistiakowsky (recipient of the Medal for Merit, Medal of Freedom, National Medal of Science, and the Priestley Medal), and Franklin Long; computer scientist Herman Goldstine (recipient of the National Medal of Science); mathematicians George Carrier (recipient of the National Medal of Science) and Richard Courant; mechanical engineer Howard Wilson Emmons; and physicists Walker Bleakney (a pioneer of mass spectrometry), Joseph O. Hirschfelder (recipient of the National Medal of Science), Norman Ramsey (Nobel laureate), Robert G. Sachs (founder and director of Argonne National Laboratory), and L.H. Thomas (the first fellow in IBM's Watson Research Center).
Model 91/38
On March 27 of 1964, the U.S. Army's Ballistic Research Laboratory, according to the 36th U.S. President's Commission (commonly known as the Warren Commission), played host to one of the most famous rifles in U.S. history. On that date, three marksmen test fired a Mannlicher–Carcano Type 38, the rifle used by Lee Harvey Oswald to assassinate President John F. Kennedy on November 22 of 1963. Only one of the three expert marksmen was able to fire three shots somewhat close to the established official time limit attributed to Oswald.[citation needed] But unlike Oswald from the 6th Floor of the Texas School Book Depository Building, these three marksmen were allowed to use a gun rest, and they were also allowed to take as much time as they needed to line up their first shot at a stationary target. Oswald shot at a moving target.
Computers
BRL played an important role in the history of computer development:[2][3]
- Sponsored the development of ENIAC - widely regarded as the first general-purpose electronic digital computer - to aid the creation of firing tables for artillery and mortars
- Developed and built several generations of computers: EDVAC, ORDVAC and BRLESC[4]
- Developed BRL-CAD, a solid geometric modeling system - now open sourced
- The network ping utility was authored by Mike Muuss of BRL in December 1983 to troubleshoot network problems[5][6]
