It is not very well known that the philosopher Karl Popper has been one of the foremost critics of the orthodox interpretation of quantum physics for about six decades. This paper reconstructs in detail most of Popper's activities on foundations of quantum mechanics (FQM) in the period of 1950s and 1960s, when his involvement in the community of quantum physicists became extensive and quite influential. Thanks to unpublished documents and correspondence, it is now possible to shed new light on Popper's central - though neglected - role in this "thought collective" of physicists concerned with FQM, and on the intellectual relationships that Popper established in this context with some of the protagonists of the debate over quantum physics (such as David Bohm, Alfed Land\'e and Henry Margenau, among many others). Foundations of quantum mechanics represented in those years also the initial ground for the embittering controversy between Popper and perhaps his most notable former student, Paul Feyerabend. I present here novel elements to further understand the origin of their troubled relationship.

卡尔·波普尔（Karl Popper）在1950年代和1960年代哲学与物理学之间处于边缘的量子辩论中被遗忘的角色

众所周知，哲学家卡尔·波普尔（Karl Popper）大约六十年来一直是对量子物理学的正统解释的最主要批评家之一。本文详细介绍了波普尔在1950年代和1960年代期间基于量子力学（FQM）开展的大多数活动，当时他在量子物理学家界的参与变得广泛且颇有影响。由于未公开的文件和通讯，现在有可能为波普尔在关注FQM的物理学家“思想集体”中的中心作用（尽管被忽视）发挥了新的作用，以及在此背景下波普尔与某些人之间建立的智力关系。量子物理学辩论的主角（例如戴维·鲍姆，阿尔弗雷德·兰德和亨利·马格瑙等）。那些年代表的量子力学基础也是波普尔和他也许是最著名的前学生保罗·费耶拉本德之间激烈争论的最初依据。我在这里介绍一些新颖的元素，以进一步了解他们陷入困境的关系的起源。
