Volumes of this journal typically include one or two historical articles, many of which celebrate the life and impact in fluid mechanics of a recently deceased contributor to the field. The Editorial Committee recently stepped beyond this model to examine whom might have been missed over the years. Naturally, even when a candidate is identified, the passing of time makes it hard to find authors with living memory of the subject. Fortunately, in the case of Professor Dr. Irmgard Flügge-Lotz there is a rare opportunity: An appropriate article appeared in the collection Women in Mathematics, coauthored by her first PhD student John Spreiter and her husband Wilhelm Flügge, both her colleagues at Stanford University. We republish this article to share her remarkable story and contributions in fluid mechanics, as she worked with Prandtl, led a research group at ONERA ( Office national d'études et de recherches aérospatiales), and eventually became the first woman professor of engineering at Stanford.

流量计算先驱 Irmgard Flügge-Lotz (1903–1974)

该期刊的卷通常包括一两篇历史文章，其中许多文章庆祝最近去世的该领域贡献者的生活和对流体力学的影响。编辑委员会最近超越了这个模型，研究了多年来可能遗漏了哪些人。当然，即使确定了候选人，时间的流逝也很难找到对该主题有鲜活记忆的作者。幸运的是，对于 Irmgard Flügge-Lotz 教授来说，有一个难得的机会：一篇合适的文章出现在 Women in Mathematics 合集中，由她的第一个博士生 John Spreiter 和她的丈夫 Wilhelm Flügge 合着，他们都是她在斯坦福大学的同事. 我们重新发表这篇文章是为了分享她在流体力学方面的非凡故事和贡献，因为她与普朗特合作，
