The East Building, completed in 1913, was the fourth building of the NBS quadrangle. Dr. Rosa and his electrical staff moved into these quarters and consolidated the division, which had been scattered throughout the other three buildings on the NBS campus. The construction of these new electrical laboritories gave Dr. Rosa's division enough space so that further developments could be made in new lines of work, such as electrical measurement instruments, illuminating engineering, and wireless telegraphy.
