The Carlyle Barton Laboratory was a semi-autonomous engineering laboratory at Johns Hopkins University, which existed from the early 1950s to 1970. This research agency operated under contract with the United States Air Force, in collaboration with the university's Department of Electrical Engineering and Computer Science. Notable Hopkins engineers who have worked in the Laboratory include Ferdinand Hamburger, Jr., Jan Michael Minkowski, and Donald D. King. The Laboratory focused on four major areas of research for the Air Force: electronic countermeasures, millimeter wave techniques, signal analysis, and physical research. In its earliest inception, this research arm was known as the Radiation Laboratory and was located on nearby 1315 St. Paul Street until 1962, when it moved to the Homewood Campus in the newly minted building of Barton Hall. The agency was renamed the Carlyle Barton Laboratory.
