In 1937, every Senator in Congress co-sponsored legislation creating a National Cancer Institute. The National Cancer Act foreshadowed two characteristics of the modern NIH. It was the first of many "categorical institutes" dedicated to a single disease or group of diseases. The NCI was also authorized to award grants and fellowships in support of research. Congress added an appropriation for a building on the new NIH campus being built in Bethesda, Maryland. Until 1944, however, the relationship between NCI and NIH was not specified. The 1944 Public Health Service Act defined NCI as a part of NIH.
