Abstract The German mathematician Olaus Henrici, 1 who was born in Denmark in 1840, studied engineering and mathematics in Germany before making his career in London. Initially, and for only a short time, he worked in an engineering business. He subsequently took on academic positions, first at University College London and then, from 1884, at the newly formed Central Institution (later Central Technical College) where he established a Laboratory of Mechanics. While at University College he became an active promoter of pure geometry and a producer of models of surfaces. In this paper I explore the geometrical side of Henrici's work, setting it into the context of his career and arguing that his interdisciplinary background was a key factor in his success as a creator of models.

“从经验中获得的知识”：Olaus Henrici——工程师、几何学家和数学模型的制造者

摘要 德国数学家奥劳斯·亨利西 (Olaus Henrici) 1840 年出生于丹麦，在伦敦开始职业生涯之前，曾在德国学习工程和数学。最初，只有很短的时间，他在一家工程公司工作。随后，他首先在伦敦大学学院担任学术职务，然后从 1884 年起在新成立的中央机构（后来的中央技术学院）建立了力学实验室。在大学期间，他成为纯几何学的积极推动者和曲面模型的制作者。在这篇论文中，我探讨了 Henrici 作品的几何方面，将其置于他的职业背景中，并认为他的跨学科背景是他作为模型创造者取得成功的关键因素。
