On May 4, 2015, the National Institutes of Health (NIH) dedicated Building 4 in honor of Lowell P. Weicker, Jr., the former U.S. Senator and former Governor of Connecticut.

In 1970, Weicker was elected to the U.S. Senate where he served for three terms, from 1971 to 1989. During his tenure, he successfully protected and defended the NIH budget and increased the appropriation for the NIH.
