Throughout her career Caldwell received many honors and awards from her peers. Two of her most meaningful moments of recognition came after her retirement. In 1960 she was awarded the Garvan Medal from the American Chemical Society, established to honor each year "an American woman for distinguished service in chemistry." The following year, Columbia University presented her with an honorary Doctor of Science degree.
Caldwell continued to prepare papers for publication until her death at home on July 1, 1972.
