Career
Hammarsten was the first to discover that RNA, at that time called the tetranucleotide of yeast nucleic acid, is present in animal organs, or more specifically in the pancreas. Before Hammarsten's discovery, only guanylic acid had been found there. His doctoral dissertation in 1924 was concerned with purification of DNA, at the time called thymonucleic acid, its ionization and osmotic pressure.
Hammarsten was elected to the Royal Swedish Academy of Sciences in 1937. He was a member of the Nobel Committee for Physiology or Medicine, and was himself nominated for a Nobel Prize in Physiology or Medicine in 1941.
In 1918, Hammarsten married Greta Norrbin, a clinical chemist and medical doctor at the Karolinska Institute in Stockholm.
As the uncle of the future author and illustrator Tove Jansson, he is credited with inventing the name "Moomintroll", telling his niece that one of these little monsters lived in the pantry, in an attempt to stop her from pilfering food.
