In this paper we reflect on the contribution, style and legacy of Professor Val Curtis, an important, and sometimes controversial, figure in the water, sanitation and hygiene (WASH) sector who sadly passed away on October 19, 2020. Across numerous scientific articles, and several books, and operational programmes, she established herself as a world-renowned scientific expert in the field of hygiene and behaviour change, as well as a major thought-leader in the WASH sector. We identify four major scientific contributions which she made over three decades of research that spanned multiple fields, including engineering, epidemiology, and psychology. Beyond her research, she tirelessly championed hygiene as a public health priority, using her talents as a communicator to secure concrete changes in relevant policy and practice. We are confident that her example, as both a public health researcher, and as a hygiene champion, will inspire future generations of WASH researchers and practitioners to be bold and ambitious.

在本文中，我们回顾了Val Curtis教授的贡献，风格和遗产，Val Curtis教授是水，环境卫生（WASH）领域的重要人物，有时甚至是有争议的人物，他于2020年10月19日不幸去世。她以及几本书和操作程序使她成为卫生和行为改变领域的世界知名科学专家，并且是WASH领域的主要思想领袖。我们确定了她在跨越工程，流行病学和心理学等多个领域的三十年研究中做出的四项重大科学贡献。除了研究之外，她还不懈地倡导将卫生作为公共卫生的重中之重，并利用自己的才能作为沟通者来确保相关政策和实践的具体变化。
