  Reports of unconventional superconductivity in UBe13 in 1983 and soon
thereafter of the possible coexistence of bulk superconductivity and spin
fluctuations in UPt3 marked the beginning of a 40-year adventure in the study
of strongly correlated quantum materials and phenomena at Los Alamos. The
subsequent discovery and exploration of heavy-fermion magnetism, cuprates,
Kondo insulators, Ce- and Pu-115 superconductors and, more broadly, quantum
states of narrow-band systems provided challenges for the next 30 years.
Progress was not made in a vacuum but benefitted from significant advances in
the Americas, Asia and Europe as well as from essential collaborations,
visitors and Los Alamos students and postdocs, many subsequently setting their
own course in SCES. As often the case, serendipity played a role in shaping
this history.
