Alfred Anderson, professor of geology at the University of Chicago from 1968, passed away on January 15, 2020. I met Fred in October 1982 when I first arrived as a postdocworkingwith Fred Ziegler. I beganmy postdoc before I had completed thefinal version of my dissertation. One of the components that I needed to complete was the photographing of thin sections. FredAndersonvery generously gave me access to his microscope—as he recalled in his acceptance speech of the Bowen Award in 2001— thiswas his startup package of $6.5Kwhenhe joined the faculty in 1968. It is a lovely microscope with an attached camera, and he also provided the film that I used to complete my dissertation. This simple, generous act completely typified Fred. He was a quiet, generous, self-effacing person who contributed broadly across volcanology and petrology to graduate, undergraduate, and continuing education students, to the Department of the Geophysical Sciences, and to the college. Fred was initially coeditor with BobNewton, but he later served as editor in chief of the Journal of Geology from 1984 to 2008. This is no small task, and Fred worked tirelessly and guided the journal with a steady hand for those 24 years. Fred mentored many students and postdocs, including in no particular order Guil Gualda, Dork Sahagian, Christine Skirius, Fanqiong Lu, Brett Peppard, Joe Dufek, Paul Wallace, and Stan Williams, among many others. They have gone on to successful careers, which I am sure are due in no small measure to Fred’s generous mentoring and continued support. Fredwas a gentle giantwhose acute observations, whether of hourglass bubbles in volcanic glasses or of volatile budgets in magmas, led to deep insights into volcanic eruptions and emplacement of granites. Fred received the Norman L. Bowen Award, the top award in volcanology in theworld, from the American Geophysical Union in 2001. Everyone should read the citation and Fred’s acceptance comments because they beautifully convey the

阿尔弗雷德·T·安德森纪念碑

阿尔弗雷德·安德森 (Alfred Anderson) 于 1968 年在芝加哥大学担任地质学教授，于 2020 年 1 月 15 日去世。 1982 年 10 月，当我第一次来到弗雷德·齐格勒 (Fred Ziegler) 时，我与弗雷德相遇。在我完成论文的最终版本之前，我开始了我的博士后工作。我需要完成的组件之一是薄片的拍摄。FredAnderson 非常慷慨地让我使用他的显微镜——正如他在 2001 年鲍文奖的获奖感言中回忆的那样——这是他 1968 年加入教职员工时的 6.5 千美元启动包。这是一个带有摄像头的可爱显微镜，他还提供了我用来完成我的论文的电影。这种简单、慷慨的行为完全代表了弗雷德。他是一个安静、慷慨、谦虚的人，他在火山学和岩石学领域做出了广泛的贡献，毕业后，本科生和继续教育学生，地球物理科学系和学院。Fred 最初是与 BobNewton 的共同主编，但后来他从 1984 年到 2008 年担任了 Journal of Geology 的主编。这不是一项小任务，这 24 年 Fred 不知疲倦地工作，并以稳健的手指导着该杂志。Fred 指导了许多学生和博士后，其中包括 Guil Gualda、Dork Sahagian、Christine Skirius、Fanqiong Lu、Brett Peppard、Joe Dufek、Paul Wallace 和 Stan Williams 等。他们的职业生涯取得了成功，我相信这在很大程度上要归功于 Fred 的慷慨指导和持续支持。弗雷德是一个温和的巨人，他敏锐的观察，无论是火山玻璃中的沙漏气泡还是岩浆中不稳定的预算，导致深入了解火山爆发和花岗岩的就位。Fred 于 2001 年获得了美国地球物理联盟颁发的世界火山学最高奖项 Norman L. Bowen 奖。 每个人都应该阅读引文和 Fred 的接受评论，因为它们精美地传达了
