• Abstract: The discovery of superfluidity in ³He in 1971, published in 1972, influenced a wide range of investigations that extend well beyond fermionic superfluids, including electronic quantum materials, ultra-cold gases and degenerate neutron matter. Observation of thermodynamic transitions from the ³He Fermi liquid to two other liquid phases, A- and B-phases, along the melting curve of liquid and solid ³He, discovered by Osheroff, Richardson and Lee, was the very first indications of ³He superfluidity leading to their Nobel prize in 1996. This is a brief retrospective specifically focused on the AB transition.
