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.

We discuss the development of Kondo physics from the resolution of the resistance minimum by J. Kondo to recent developments in physics. The Kondo effect has given a great impact to all areas of physics. This reminds us that physics is one unified science. Kondo's pioneering work has led major developments in physics. We show brief history of the Kondo effect and discuss the Kondo effect from several points of view that appeared to be important through conversations with Prof. J. Kondo.
我们讨论了近藤物理学的发展，从 J. 近藤对电阻最小值的解析到物理学的最新发展。近藤效应对物理学的各个领域都产生了巨大影响。这提醒我们物理学是一门统一的科学。近藤的开创性工作引领了物理学的重大发展。通过与 J. Kondo 教授的交谈，我们简要介绍了近藤效应的历史，并从几个重要的角度讨论了近藤效应。

In the first part of this article, I briefly review early research activities concerning strongly correlated electron systems, beginning with the discovery of superconductivity and the first observation of a resistance minimum in nominally pure Cu-metal, which was explained many years later by Kondo. I will also address the antagonistic behavior of conventional (BCS) superconductivity and magnetism. The main focus of this paper is on the discovery of non-BCS-type superconductivity in the Kondo-lattice system CeCu$_2$Si$_2$, a prototypical heavy-fermion metal. Here, the superconducting state is created by a periodic lattice of 100% of magnetic Ce^3+ ions. Meanwhile, more than fifty lanthanide-, actinide-, and transition-metal-based intermetallic compounds are known to belong to the class of heavy-fermion superconductors. Finally, I will give my personal view of the current knowledge of this kind of unconventional superconductivity.
